Z77A-GD65 hangs on A2 at post...

About a week ago i started getting this hang on boot, it will show the codes down in the bottom right of an otherwise blank screen and it stops at A2, it will sit there for anywhere from 30 seconds to 3 minutes, then the post finishes it shows the splash screen and boots right into windows no problem.
I see on the forums that A2 is related to the SATA drives. So i unplugged my DVD drive, still got it, unplugged my secondary hard drive, still got it, unplugged my SSD, no hang on A2 but thats to be expected because there is no drive attached.
If i connect the DVD drive only i dont get the hang, if i connect the DVD and my SSD no hang, but if i connect all three it hangs.
Now i know what your going to say, its a bad hard drive... NO
I replaced the secondary drive twice with two brand new out of the box 2tb WD Red drives i have on hand, i also tried a WD Green thats a brand new 1tb. The original drive is a WD Black.
I went into the bios and removed the second hard drive from the boot options, also disabled it in BBS boot priority. But it still hangs on A2. Some said disable USB Legacy Support, i tried that, still hangs.
Latest bios installed, latest firmware on the OCZ SSD, nothing else that i can think of to try or do to resolve it.
Anyone got some ideas? The board and drives are only a few months old and have been flawless up until last week.

SSD's are far more reliable than standard HD's from what i have seen. OCZ and Samsung are the two brands i have not had any issues with, Adata isn't bad but some of them have acted up but firmware fixed that.
I tried moving all the ports around and swapping cables, but i think i finally fixed it. The cable to the DVD drive was brand new but when i swapped it the A2 hang quit.
Back to 10 second boots and reliability!

Z77a-gd65 hangs on bios screen and also doesn't boot

i7 3770k
MSI GTX 670
2x8GB 1300 memory.
I cannot get into the bios. If I hook the monitor to the gtx 670, I can get it to display the msi bios screen "temperature, boot device priority" but that's it. There's no data, no temperature, just like it put the bios image up and then hung.
Right after hitting the cmos button, I get the following:
E7751 IMS v10.5 4/27/2012
i7 3770k 3.5ghz
16gb ddr 1333 dual channel
It doesn't seem to let me hit "f1 to setup" or "f2 to continue" with a ps2 keyboard.
If I boot from the cd to try and install winki, there's some info that flashes too fast to see but its to the choice of install, and then whatever option I choose, it will display a clear screen with the logo and eventually the screen goes black with a blinking cursor.
If I boot from a usb linux drive I have, it again goes through the boot choices, and then the screen goes black a few seconds in. Doing this I think I got the mainboard leds to display "ff" otherwise they display either "00" or "ad" or "ae".
The monitor is apple monitor through an adc to dvi adapter. I've used this for years on an ati radeon on a p4 windows setup so it shouldn't be a problem but... if I hook the monitor directly to the mainboard onboard video, the bios screen graphics stop hanging open, the screen just immediately goes black.
I've tried clearing the bios with the button, switching the multibios, and jumpering the cmos with the power off.
I have not tried flashing the bios, I was thinking about doing that through winki but it won't load.
Thanks.

I tried just one stick of ram in a different slot but no difference.
And as in my first post I tried the onboard a bit but it was about the same. Actually I forgot what I tried, I just now tried the apple cinema display to the onboard video card and unpowered the gtx 670 without taking it off the board and the display doesn't come on at all.
I think that was what it was last time I tried the onboard, that I thought it might be something about the adc-dvi converter. But it works besides.
Why would it be able to get to the boot choice screen but not the bios though? The PSU has a 7 year warranty, its probably decent, manual says 62.4a +12v .8a -12v
One other thing, if this matters. The first two blue lights are always on on the motherboard, the voltage indicators or whatever, but when it tries to load winki, the other blue lights blink. And right now, with the monitor on the onboard, all the lights are on. But the monitor isn't.
Also, do you need a mouse plugged in, that probably wouldn't make a difference, I think I've tried that as well.

Z77A-GD65 Multiple BIOS Issues - B4 Hang, Splash Screen Blinking

Back in November 2012, I built a home server with a Z77A-GD65. Lately, I've noticed some strange things happening that I've been trying to research but to no avail.
First off, I get the B4 code hang-up whenever I'm booting. This doesn't matter if it's a cold boot or a reboot, it hangs on B4 for about 10-15 seconds, flashes 92 really quick, and then goes to A2 which it stays for another 5 or so seconds. After that I get the MSI splash screen for about 1 second, then it blinks 5 times. After that it goes into Windows just fine.
The blinking is a new issue, the B4 hang is not. I've read from multiple posts that this is a USB issue. When I disable USB legacy support, the issue goes away, but of course then I can't have legacy support. I have yet to figure out what exact device is causing it. In the process of trying to figure this out, I updated BIOS to A.A0. After updating to this version of BIOS the splash screen blinks 5 times before going to the "Starting Windows" splash screen. This is a more difficult issue to figure out why it's doing this because if you search for "BIOS" and "flash" or "flashes" or "flashing", you typically get results for flashing your BIOS. Hence, why I'm using the term "blinking". But even then I can't really find a solution out there.
I also happened to see that the website for the Z77A-GD65 is showing a newer BIOS version, but I'm unable to flash this (at least using M-Flash). I threw it on a USB, re-enabled USB legacy and whenever I click on it to install, the BIOS screen hard locks. The screen just freezes exactly where it's at in the BIOS and the mouse is dead. However, I can CTRL+ALT+DEL on the keyboard and it will reboot the system so I don't need to power cycle the computer. Not sure why this is happening either. Perhaps I need to flash this a different way? Maybe I don't need to flash this at all?
I could really use some input here on why this is happening.
As for the specs on my system, they're as follows:
i7-3770K overclocked to 4.2 Ghz by using the Turbo Mode in BIOS
32GB Komputerbay DDR3 PC3-12800 1600MHz DIMM with Low Profile Blue Heatspreaders Quad Channel RAM | 9-9-9-24 XMP ready

for peripherals
1 - Microsoft 360 Wireless controller adapter (legit one, not the knockoff although I had a knockoff prior to getting the real deal)
1 - Logitech Wireless USB Keyboard with Touchpad
I tried to be thorough. Thanks in advance for any help!

Probably a USB device problem.
This is a candidate, as well as mouse and keyboard. Disconnect USB devices one at a time to find the culprit.
A lot of devices running. PSU a +12V single rail or is it multi rail? A rail going to the graphics or components may not be enough amps. My best guess is the card reader.
For UEFI/BIOS flashing, select your mainboard here and use the forum flash method;
I'll definitely try unplugging some of these USB devices to see if that helps with the B4 hang issue.
As for the PSU, according to the description for it on Newegg: "Four industry-leading independent +12v rails are provided for more stable and safer power output." It has two rails going to the GPU. The GPU is a new addition to the system and so I wasn't running it until recently. The issues were occurring beforehand, but you're right that this PSU is underpowered for the rig considering PowerColor recommends a minimum of 500w. I'm going to be buying a larger capacity one sometime in the very near future. Any recommendations on good modular PSU's? What's a good way to tell what wattage to get?
Thanks for letting me know about the forum flash method. I'll be back later when I have some results.

Z77A-GD65 won't post

My newly built PC wouldn't start the other day:
Z77A-GD65 motherboard
Core i5 3570K
8GB Corsair Vengeance RAM
GTX 660
Corsair TX 750W PSU
Corsair Hydro 100i CPU Cooler
Corsair Obsidian 650D tower
It sort of tried to power up, fans would start spinning and then 1 second later it would all power down. This cycle would continue until I switched it off at the PSU. I took a look inside and noticed that the DRMOS red LED was lighting up. The LED 1 was also flashing blue.
All the reading I did on the problem suggested either the PSU or the motherboard was on the blink, so before I RMAed the motherboard I bought a new Corsair CX 750M PSU and set the motherboard on a wooden table top with just the RAM, CPU and standard Intel cooler inserted.
Now the DRMOS light no longer comes on but the LED 1 light flashes and goes out, the system "reboots", this cycle continuing until I switch off the power. The CPU fan isn't even spinning up now though.
Now 2 things:
1. The motherboard I got cheap as an "open box" item from Aria PC, so I have a feeling it may have been dodgy to begin with.
2. My old PSU didn't have an 8-pin EPS connector so I bought an adapter than plugged into the old style standard 4-pin IDE drive power connector. I hope this hasn't somehow fried the motherboard!
I can't find anything that tells me what the LED 1 light flashing on its own in this way means. Does anyone know?
Please tell me it's just the motherboard that's fried and not my beloved 3570K!
Should also say the debug LED panel doesn't even light up with any values and I've also tried switching the BIOS to A (it was set to B for some reason). I've also tried clearing the CMOS. Didn't help.

Quote from: badboy2k on 26-June-13, 06:49:52
A0 is IDE Detect if its stopping there your drive mode sounds like its not set correctly as its not seeing your OS drive if its hanging! and AD is Ready to Boot Event (loading OS) this is either a OS from a different chipset or a bad drive mode or both happening!
Agree. It sounds so close to working. Maybe the onboard graphics will work to try and figure out how to get it set up right.
Also sounds like he may need a clean formatted HDD/SSD to place a fresh OS install on.

Z77A-GD65 build won't post, I've tried everything I can think of...

Hello all,
Here are the parts:
MSI Z77A-GD65 mobo
Intel i5-3570K LGA 1155
MSI N560GTX-TiHawk graphics card
Samsung 30nm DDR3 RAM 2x 4gb
Corsair H100 cooling
Samsung 830SSD
Silverstone ST1000 1000watt power supply (this and my HDD are the only components from my old build and the HDD isn't attached)
I plug everything in, check and recheck, and all the fans and lights turn on for maybe a second and shut off with no beeps. I've RMA'd the board and processor to no avail. I've been breadboarding the build since the first time it failed to start. I checked the power supply with the paper clip test and on my old build to see if it was the problem and it was not as far as I can tell. It still functions as it should with the old build.
I followed multiple instructions to trouble shoot this problem and haven't gotten anywhere. I've tried with just the CPU, H100 and a stick of RAM and still get the same issue. I've tried both sticks separately in each socket and had the same issue, as well as a completely different set of sticks. I've switch the CPU cooler from the H100 to the stock one with no results. Reseated everything. Reset the CMOS. This build has never posted so nothing is overclocked and nothing has had any firmware updates. I've tried everything I can think of to get this problem fixed and I can't find the solution. Any suggestions would be greatly appreciated. I should probably note that my old build is pretty old so most of the new parts aren't compatible with it so I can't update firmware and such on my own if those are possible issues.
Thanks.
PS. Posting from my IPad so I apologize for any typos.

Quote from: Bernhard on 27-July-12, 12:50:02
Are you saying that this is a new board and processor after having the same problems on the previous parts ?
I bought all the parts for this build, had the issue and though it was mobo caused so I sent that back. Then I had the same issue with the replacement so i sent the processor back. Same issue with the replace ment processor.
Quote from: xmad on 27-July-12, 19:37:58
Just to ask a probably silly question, but does that old psu have the proper connectors? Are the 4 pin connectors near the cpu filled? Is the backplate on backwards and shorting something?
Yes, it has all the right ports and connections. The backplate is correct as far as I can tell.
After talking with MSI and a local computer shop my current best guess is that I got a board with an old version of the bios that isn't compatible with the processor I have. That means to bios will need to be flash updated, something I have no idea how to do. My local computer shop said they could do it for 65$ but with no garuntees if something goes wrong. So, I'm going to send it to MSI and have them do it.
Thanks for the ideas guys, if you can think of anything else let me know.

Help! Z77A-GD65 mobo won't post - Debug LED says dE - no beeps

I'm not sure where to start. I came home to find my computer off. Turning it back on results in all the lights and fans coming back on. No post and no beeps. Screens are just blank.
The 8 blue CPU phase LED lights above the CPU are all on. Nothing unusual there.
The Debug LED lights show "dE" which isn't documented at all in the manual. Does anyone know what this error code means?
Z77A GD65 mobo with corei7 3770 - SSD - 4x4GB Corsair RAM - No GPU. Otherwise nothing special.
Where's a good place to start? Reset the CMOS/BIOS? Swap out memory sticks?

http://www.ami.com/support/doc/AMI_Aptio_4.x_Status_Codes_PUB.pdf
D3 or DE?
0xD0 – 0xDF DXE errors
0xD3 Some of the Architectural Protocols are not available
Power off, battery removed, CMOS clear may be worth trying. Yes, test each stick individually in the DIMM2 slot.
Added: Might want to hold off swapping BIOS chips until some more investigation is completed. Don't want to take the chance of possibly corrupting the backup BIOS chip at this point.

MSI Z77A-GD65 No Post

When I first started my new system, I did get a display and entered the BIOS. I changed the boot order to put my optical drive first, put in a live CD, restarted, and got a black screen. I ejected the CD, restarted, and got a black screen again. I didn't get a display again until I disconnected all my drives whereupon I got a map error and was able to get back into the BIOS. A web search indicated this is a bug that occurs when no drives are connected so I reconnected the drives, restarted, and got a black screen again. I disconnected the drives again and restarted but I got a black screen again (no map error this time). I tried connecting my monitor to the graphics card instead of the motherboard and that didn't work. I tried removing the graphics card and video capture card and that didn't work. I tried clearing the CMOS by pushing the button and even removing the battery for several minutes and that didn't work.
Here's where things get weird. I tried testing the RAM by pulling out one stick and the system kept restarting itself: it would turn on then power off a few seconds later then, after a few seconds, start up again, etc. I had to wait till it powered off and quickly pull out the power supply's cord to get it to stop. I removed that stick and put the other one in instead and the same endless loop of restarting happened again. When I put both sticks back in it stopped restarting.
Since I couldn't get into BIOS A, I switched to BIOS B and got a display again. There was no option to restore BIOS A so I was forced to continue using BIOS B. Since my graphics card was removed at this point, I changed the BIOS to IGD instead of PEG for graphics and shut down. I reconnected my drives then restarted and got a display again and entered the BIOS. I changed the boot order to put my optical drive first, put in a live CD, restarted, and got a black screen. I ejected the CD, restarted and got a black screen. I disconnected the drives and restarted hoping I would get a map error and could get back into the BIOS but got a black screen again. I've tried switching back to BIOS A but still can't get a display.
I tested the RAM by putting it in my old desktop one stick at a time, and then both sticks at once, and it worked fine. I installed the optical drive and one of the hard drives into my old desktop and successfully installed and booted linux off of it with the no problems. The second hard drive does appear to be borked and my old desktop froze when I tried to boot with that drive installed. However I've tried starting my new system multiple times without that damaged drive connected and I still get a black screen so I don't see how it could be the problem.
The LED on the motherboard mostly alternates between 19 and 72. It will run through a bunch of codes too quickly to read then pause for a second on 19 (Early South Bridge Initialization) then run through a bunch of codes too quickly to read then pause for a second on 72 (Late South Bridge Initialization) then go back to 19, etc. I've sometimes also seen it pause for a second on 55 (Early Memory Initialization) and 4F (which doesn't appear in the manual).
I'm guessing it has to be the motherboard or CPU but I don't know which. I don't have another motherboard to test the CPU on and no other CPU to test on this motherboard (the old desktop is AMD).
Hardware:
MSI Z77A-GD65 motherboard
Intel Core i5-3570K CPU
G.Skill DDR3-1600 CL9 1.5v 4096MB (x2) RAM (tested in old desktop)
Seagate Barracuda 1TB hard drive (tested in old desktop)
Pioneer BDR-208DBK blu-ray drive (tested in old desktop)
Corsair Obsidian 550D case
Seasonic G Series 550W power supply
Samsung S23B550V monitor (tested with old desktop)
Currently disconnected hardware:
HIS Radeon HD 7870 GHz Edition graphics card
Seagate Barracuda 3TB hard drive (believed to be broken)
Black Magic Design Intensity Pro capture card

Test each stick in Dimm 2 (2nd from the cpu) Make sure they are installed into DIMMS 2 & 4 (2nd from cpu and last)
Did you try a full cmos clear on Bios A?
If so, you can recover using this guide:
https://forum-en.msi.com/index.php?topic=160450.0
With the z77a-gd65, you will need to flash bios B to version 10.5. In that version in the security section is a multi bios update. Use that and it will recover bios A.

Varying boot times - Z77A-GD65

I have a new build and find that the boot times seem to vary for no apparent reason. Most of the time I will see the MSI splash screen within 15 seconds and then it boots quickly into windows. However, some times it will hang up on codes A2, B4, C3, or CA for up to 45 seconds before the splash screen appears and then it boots fine. I will note that no matter how long the boot takes, the system runs flawlessly and has never crashed or had any odd behavior other than the varying boot times. I see from the manual that A2 and B4 are Onboard Devices Initialize and Detect, but this happens randomly without changing any of the onboard devices. I ran memtest86 on the ram for over 12 hours and 6 passes and got no errors.
Anyone else have this experience or any suggestions on what may be causing it? I'm OK with it if others have the same experience and it is normal. I'm just concerned that it is a sign of some sort of problem.
First post, thanks in advance.
Intel i5-3570K (stock speeds)
MSI Z77A-GD65 board
Seasonic M12II 750 w psu
Corsair Vengeance LP Ram (16 GB)
Samsung Pro 840 128GB SSD drive (boot drive)
WD Caviar Black 500 GB HDD (data drive)
Win 7 Pro
ATI Firepro V5800 graphics
Noctua NH-U12P SE2 heatsink
Corsair Obsidian 550D Case

I tried disabling the PCIE GEN3 and I don't think it helped. I did a few restarts and still got a hang up on CA, whatever that is. Thanks for the codes. The most common ones I get seem to be:
A2 - IDE Detect
B2 - Legacy Option ROM initialization
B4 - USB Hot plug
C3 or C6 - OEM BDS Initialization Code
CA - no idea
The strangest thing is that I would say 7 out of 10 times it starts up perfect. The other 3 it will hang on something, but then it still boots and runs perfect. It just strikes me odd that I can make no changes whatsoever and it can go from perfect to hanging up. If anyone has any other suggestions for any of those codes, please feel free to respond. Thanks.

Z77A-GD65 ram and DR. mos problem after 2 years without any HW change or OC!

Hi guys, i have three Z77A-GD65 from 2 years with the same hardware config, no overclock or others OC settings ....simply default bios settings; in this last 2 months, not at the same time, all of my 3 mainboards have the same identical problem.
One day, from nowhere, without any reason, i start my pc and mobo don't start, hangs with code 55 ( memory error) and Dr mos alarm led goes on, i try to reset bios .. nothing.
I Switch multibios to "B" bios and works perfectly .. i've tested all of RAM modules and result works perfectly !! .... all of three mainboards have the same identical problem!!
Now i use all my 3 PCs with "B" bios and works perfectly, because "A" bios hangs always with code 55 and with Dr. mos alarm led on, i try to update and downgrade "A" bios ... nothing to do ... "A" bios don't work anymore.
Any idea?

Quote from: Nichrome on 19-July-14, 02:32:51
Don't have to be rude
If same problem is on 3 motherboards then is something wrong with RAM or BIOS not the motherboard
>>Posting Guide<< Reminding again if you want to receive any help.
Nichrome, you misunderstood! ... I just responded to your affirmation .. that's all, it was not my intention to was "rude" as you wrote! OK?
Ram modules have been tested on other Asus mainboard .. .. no read/write errors and no hangs problems ... so all Ram modules are fine
About bios ..... maybe primary bios is physically damaged.... i try to reflash bios also with old version .. no way .. maybe primary bios damage in all 3 mainboards !! very strange!!! ... you know if there's a know manufacturing defect on this MB bios maybe on a particular MB serial part number? because i bought all 3 mainboards at same time about 2 years ago.
Quote from: Sea Dog on 19-July-14, 02:40:52
Obviously, there is 'something' that has caused BIOS corruption in all 3 mainboards A chips. Whatever that 'something' is, it may happen to the backup B chips as well. Recommend to concentrate on finding this 'something', what the common denominator is, and restoring BIOS chips A before the mainboards may become expensive paperweights. A shop with an SPI flash programmer device can fix the broken BIOS chips if not comfortable with doing the recovery procedure yourself.
Hi, yes i agree, In fact, my fear is to have, in a while, these mainboard totally unusable! ..... i think that primary bios is physically damaged or i hope, software damaged, I would try to recover it, if it's only a software problem (i hope so) ... do you know a procedure to completely erase cleanly that reflash the primary bios? i try to use dos MSI flash utility with "/p /b /n" options .. no success to restore A bios ... same story ... error 55 and DR-mos alarm led on.

Z77A-GD65 / Video issues

Hey All
Got a real weird issue going on
Randomly when playing games my computer will shutdown and reboot. When it boots up the video card is blurry during Post and bios splash screen. Once windows attempts to load the computer reboots again.
Changing to the onboard video card works fine
If I swap the PCI-E to another slot it will work again but the issue will reoccur in a matter of time - can be days or minutes
Video Card runs in high load environments such as ARMA3 and Starcraft with issues. Previously had not experienced an issue.
It's just really weird
System
MB: MSI Z77A-GD65
Video: GTX 580
Memory: 16GB Gskill 2400
Any help or ideas would be awesome
Regards,
Mag

could be overheating for sure so like dude said check the temps under load and see if its temp is very high?
also it could be RAM errors so try >>Memtest86<< and see if it throws errors or if the computer restarts while its active?
could also be PSU related as you have not listed what power supply you have as it may be having a power shutdown issue as the PSU is not capable of sustaining a stable power delivery?

Z77A-GD65 boot issue!

Hey.
I have this Z77A-GD65 motherboard which I bought around July 2012, which has been working great until this morning. First of all, I don't do any overclocking, It has no meaning to me and I didn't change anything on the BIOS, not even used it prior to this problem.
Problem is, PC won't post, It will turn on for 3-4 secs until reaching debug code 55 then it will simply shutdown and restart by itself, going into a cycle, just let me repeat, there is no BIOS, no post only black screen.
I tried switching Bios A and B, clearing data on both Bios A and B, replacing the Bios battery. I replaced the Core i5 3750K with a Core i7, I changed memory sticks, even replaced the 670 GTX card with a 660Ti card. Replaced my CoolerMaster PSU with a Corsair one and none of these changes helped.
I did this both inside the case and outside the case and gave the motherboard a good airblow to remove the little dust it had on it.
All the other component worked just fine in another PC.
So basically, I did every troubleshooting I know, It feels like a shortcut but I inspected the motherboard and it seems to be in good physical condition.
I think it needs a RMA, whats the best thing to do now?
Thx for any help!

You are in South America?
You could also just email [email protected] if you wished. Might be recommended if that is the case due to the nearest service center being in the USA. Unless they opened a new one recently.
Yup:

Z77A-GD65 SLI Bridge Length??

So i have a Z77A-GD65, not the gaming edition though they look to be the same, anyway i just wanted to toss in a second card in SLI but then i realized this board never came with an SLI bridge in the box...
The spacing is pretty wide on the first and second slot. What is the length, without my having to pull the system out from under the void i like to call my desk and open it up and measure, that i need for an SLI bridge? Would a flexible 4" be long enough or would it take a longer one like a 4.5"??
Going to have to order one so wanted to be sure and i am sure others on here have done this... Thanks!

Sorry for the LONG delay in replying... Got busy, forgot about this post...
Dug around for a half a day and finally located a SLI bridge in my junk.. er parts... boxes!! LOL
Thanks for the offer though! I knew i had one somewhere that would work. First one i found was too short, then the next one i found was sooo long that i had a huge loop of excess, but like goldi locks would say the third one was Just Right... LOL
The setup is done and running and the performance is beautiful... :-)

I wanted to have the SSDs in RAID0 with Win7 and the games on it, then a volume on the 2TB that the RAID backs up to, with the remaining 1.5TB just free storage space in another volume. I couldn't get raid past Win7's Where Do You Want To Install screen during installation, so I ended up installing the OS on just one SSD. I figured I'd backup the functioning OS to the 2TB then rebuild the RAID array and copy the OS back onto it.
The system had been up an running for a full day, being updated left and right nonstop, several big games put in, etc etc, everything was running fine until I decided to run MSI Live Update and started pumping in updates. Constant errors as I went along, but generally it'd just skip to the next installation attempt. When it got down to updating the BIOS and did it's DOS injection thing, it for forcefully shut down the PC, restarted, did Post, flashed the BIOS wallpaper, restarted again, Posted, no BIOS wallpaper, just endless "Missing Operating System". Walked away, went to bed, back up and at it for a few minutes (Will be back tonight for however long it takes to get it fixed). I switched the BIOS switch over, no dice. Feels like it's a BIOS "OS" that's gone, and that a BIOS reset/flash is in order or something, but I've never done these things.
Thanks in advance for any rendered assistance that leads to resolution.

The SSDs are definitely hooked up where they're supposed to go; the motherboard had a little sticker n' everything for where the two SSD dedicated SATA 6.0gbps ports were :P AND my case has 2 specific slots for SSDs which don't use the hotswap electronics PCB passthrough like the other 4 bays, which is where the 2T is installed. I was going to take the 2TB out and hook it up normally and see if that changed the speeds, but I'm leaning towards wishful thinking. Did I mention I went and made several volumes with different file cluster sizes to test and see if that was the issue? Alas, all were borked. It still confuses me though because every once n' awhile it'd do massive burst speeds the way it's supposed to.
As far as I can recall I'm using up to date BIOS, the last one or two. One BIOS switch is set for the last BIOS, the other switch is a step back devoid of the Windows 8 stuff. I believe I have all the drivers up to date as well. Intel 335's are literally brand new, mine hadn't been more than 3 weeks old off the production line when I received them; IE, they should pretty much have the latest firmware on them which spares me the risk of destroying something precious
I MIGHT have a SATA external enclosure around here somewhere, if so, the 2TB could go in that for additional testing until I figure out where it's sustaining speeds of 2-10MB vs 100-150MB/second.
Meanwhile, the good news is that the system has been fully operational and hella stable. I hadn't slept in almost 3 days, playing and installing stuff nonstop. The system continues to run cooler (32c@stock CPU speed) as the thermal paste sets in, the knocking sound of the fan in the PSU has gone away upon me reawakening a bit ago, and amazingly, this massive system (with EIGHT fans) draws only 60-65 watts while desktopping. That's just astounding

Z77A-GD65 power issue/bad system board?

Looking for advice. I am afraid its a bad board, but some symptoms point at power which also makes no sense.
This is what the WHOLE system should look like.
MSI Z77A-GD65 system board
Intel 3770K 3.5Ghz
Anted Kuhler H20 620
G.Skills RipJaws 16GB 1600Mhz DDR3 F3-14900CL9Q-16GBXL (on the test list)
Asus nVidia GTX 680 video card
OCX Vertex 3 256MB SSD
Seagate 500GB data drive
Razer Lycosa Keyboard
Razer DeathAdder Mouse
Antec Sonata IV case with Neo ECO 620W power supply
It seems to me that 620W should be more than enough. According to my calculations thats roughly 330W of power draw against a 620W powersupply.
I am not currently over clocking.
So what the system does look like is:
If I connect the 500GB drive then windows starts rebooting as soon as the Windows logo comes up.
If I place all four sticks of RAM in the system windows starts rebooting as soon as the Windows logo comes up.
If I leave the 500GB standard sata drive off and only use 3 sticks of RAM... well we get a solid system and I am writing this message on it.
3 sticks of ram appear to work in any 3 slots and allow the system to boot, except 1,3,4. That combo also resulted in the reboots at the windows logo.
I first thought it was RAM, originally I was using Corsair Vengeance. I saw some posts here about people having the same problem, and noted that the Corsiar RAM was not tested and switch to a the tested G.Skill instead.
Any ideas? It does not completely seem like a System board issue, but it certainly should not be power. All heat levels are well within normal and as I said the system works great if I leave off the drive and one stick of RAM.
Thanks guys....

System torn down, and put back together. (Found out I was out of Thrermal Compound, so I had to run to the store to get some.)
No long leads, only 9 stand offs matching each mount point on the systemboard.
Back together... problem is the exact same.
However, back to the hard drive issue. I decided to play with that since I was getting no where with 4 sticks of RAM.
What I have discovered is that with NO sata cable connecting the drive to the system board, if I try to power the two 250GB standard sata drives the system reboots just as the Windows logo should come up.
The fact that this behavior is so close to the RAM behavior... I am back to thinking its a power issue, though system board is still a chance... its just easier to buy a new better power supply than the Antec Neo Power 620 that came with the case. (I have not ever had a problem with Antec before, and will likely just buy one of their higher end power supplies to replace it, but I think I will try it next, just in case.)
I am not seeing any strange behavior power wise as far as any monitor shows... but connecting power to a sata drive that is NOT connected with a sata cable and causing a reboot just screams power at me.
Anymore thoughts today. In the mean time off to play Secret World with just the SSD and two sticks of RAM, which still runs rock solid.

Z77A-GD65 hangs on A2 at post...
