Z77 Mpower - No video signal on boot - Debug code "Ad"

Hi, I can't get any video signal from my mobo, it seems that it can't boot at all.
I just plugged CPU (i7 3770k), CPU cooler (Noctua NH-D14) and 1 RAM (8gb DDR3 2400MHz), no vga, hd or dvd writer, then I obviously plugged the 24 pin connector from the PSU and the 8 pin connector for additional CPU power.
I have my monitor directly plugged to motherboard but when I turn on my pc, even if fans are working and motherboard leds are on, I still don't have any video signal and on the motherboard I can see the debug code "Ad".
Please can you explain what is happening?
Thank you very much for any advice and sorry for my bad english.

I tried to reseating the CPU and nothing changed, then I reset the CMOS, waited for a couple of minutes, restored the power, and the debug code became "A0", but after about another minute I retried to turn on the PC and the Debug code returned "Ad".
I'm quite frustrated.
Side Note: For my try I didn't use the boxed cpu cooler, I just installed my cooler without plugging the fan cable to the "CPU fan" pins, i thought it was sufficient to see if my motherboard boots, isn't it?
Update: I tried ro reset bios again and plug change the RAM stick in solt2 with the other one. Again the system was unable to boot but the debug code became B4. After a couple of minutes I tried to boot again without touching anything and the debug code returned "Ad", I can't give an explanation to these apparently random debug codes
Update 2:Now I switched ram slot, from slot 2 I mounted ram stick to slot 4 and reset cmos again. The first boot after resetting gave me debug code "64" then again, shout down, wait a couple of minutes, turn on Pc and... debug code "Ad" again.
It seems that first boot after cmos reset the mobo gives me a random debug code, then it returns "Ad" as always for the following boots.

BRAND NEW MSI x99s Gaming 7 Won't Boot, Debug Code 00

Just completed my build and my pc won't boot. Everything plugged directly into the psu is working but fans plugged into mother board don't spin and getting debug code 00 nothing displayed on screen.

Hmm ok.
What you could do is: try each stick on its own, in every single DIMM slot. Make note which slots/sticks work or dont work. Then add to 1 (known to work) RAM stick and try moving this single one around all DIMMs again. Do the same until you get a failure or if works fine.
Which slots did you use by the way?

I then added the 4th one back in and now it boots. Any ideas why just switching those 2 positions would change anything??
Maybe for the first time it didnt go all the way down?

MSI Z77 MPower - Boot issues (A2 debug code and more)

Hey guys,
I've been trying to get my new computer build working but I have encountered several issues when trying to boot the computer.
Before putting everything inside my case, I tested the motherboard + CPU + 1 stick of ram to make sure everything was working. I had issues in the past where I had to remove everything once I had things mounted.
Everything seemed to work and I got into the BIOS and looked like everything was good.
I mounted it in the case with the same configuration and I was able to get into the BIOS again. So I thought everything must be ok.
Fast forward a couple hours later after I finish plugging everything in, I try to turn it on but it just gets into this boot loop.
Turn on > Fans spin for a couple seconds > turns off > repeat. This just kept going on and on and I wasn't exactly sure what was going on.
I started to unplug components and when I only had the Mobo + CPU + 2 sticks of ram in I was able to get into the BIOS.
I plugged things in one at a time and when I plugged in my SSD it would work.. but when I added another drive I would start getting the A2 Debug message on my board.
I would continually get this A2 debug message and I am not sure what to do to get it to work.
I have updated my BIOS to the latest ones and it is still not working.
Could this be an issue with my PSU? I really hope it's not the MOBO..
My System:
i7 3770k
CoolerMaster 212 Evo
MSI M77 MPower
16GB DDR3 Ram
7870PCS+ Tahiti LE
Corsair HX650 PSU

Quote
I've tested it with one stick and 2 SSDs and it doesn't give me the A2 debug code.
Do you have any different ram to test with?
What ram exactly are you using?
You may perhaps be able to set the ram timings in bios to JEDEC standard 9-9-9-24 1600 perhaps

MSI Z77 MPower - Disabled integrated video, but it keeps coming back

I have a brand new Z77 MPower board paired with an i7 3770K CPU. I am running the most recent BIOS. In BIOS, I have "Virtu Technology" set to "Disabled" and "Initiate Graphic Adapter" is set to "PEG". As I understand it, this should cause my computer to only use the discrete card (which is an XFX HD 7870, by the way). This is all good and fine, and it generally works as it's supposed to.
However, every once in a while (maybe every 3rd or 4th boot into Windows), something strange happens: the 3770K's onboard video (Intel HD 4000) shows up in device manager as "Standard VGA adapter", and Windows Update wants to install an updated driver for Intel HD 4000. If I install the driver, I get a black screen, and I cannot get Windows to properly boot unless I boot into Safe Mode and remove the Intel driver with a utility like Driver Sweeper or Display Driver Remover. I have the "Standard VGA Adapter" disabled in Device Manager, but Windows Update still wants to update the driver. It is very annoying, and I've never had a board that didn't respect the BIOS setting to disable onboard video. What is going on here? Is there something that I'm overlooking in the BIOS?
I suppose that I could deal with it if the stupid Intel driver didn't cause my system to lock up. I guess an acceptable workaround would be to find a working driver for that, but what I really want is for the onboard video to stop showing up in Device Manager. Any ideas?

Never heard of a Z77 MPower reporting false temps. Could be cooler is somehow wedged on the cpu and is not fully in contact with the heatspreader. Try reseating it.
Fast reply for a Saturday morning, thanks!
I did Google it and couldn't find anyone else reporting bad temperatures, so I'm going to assume maybe I've made a mistake. (none of us are above failure!) Been talking to some other computer builder friends on Facebook and everyone is pretty much in agreement that I should reseat the heatsink, I'm also going to use the Zalman paste, though.
Could I also bother you and ask if you know if less USB ports are enabled since I'm using a 2nd gen Intel Core CPU and not a 3rd gen? I know the PCI-E lanes are less because of it, but I'm not sure if USB would be included or not, going to try and find that in the manual, hopefully it will say something.
As of right now though, it looks like only 4 total USB ports are available, 2x USB 3.0 ports on the back, and the 2 front USB 2.0 ports I plugged into the high powered header on the bottom of the board. The 2 gaming port USB 2.0 ports don't even work. =/

Z77 MPOWER - Debug code A2

I've been using this motherboard for a solid month until last Saturday when I shut down my pc and I walk away being done for the day.
To my surprise the motherboard boots itself as I'm walking away and it's refusing to go post bios and keeps giving different error codes depending on what I pull out. Having switched all parts and taken everything out the only debug code that remains is A2.
Specs
Z77 MPOWER
3570 @ stock with h80 cooler
2 x 8 gig ram 1600
2x 7950 @ stock
2 ssd's, 1 hdd and 1 DVD drive.
Corsair ax 750.
What I've done.
Pull out memory cards 1 by 1.
Pull out the Graphic Card, tried different as well.
Pull out all SATA cables and connectors.
Pull out everything hooked to the backplate.
Reset CMOS (Will boot, when prompting to go into bios to change settings it will shut down and go back to A2)
Switch to DUAL BIOS (Will boot, when prompting to go into bios to change settings it will shut down and go back to A2)
I've RMA'd the motherboard but the shop said a pin was bend and refused to fix the motherboard. Having received the motherboard back and inspected the socket I did indeed notice a slightly bend pin.
However this pin is so slightly bend that it's not touching any of the other pins and it took me a "whole" 2 minutes to bend it back in line with the rest. Whatever this was caused by me or them I'm unsure, hell the pin is so slightly bend that I doubt it would interrupt with normal operating procedures.
The motherboard however is still not functioning and stuck on the A2 error code. The CPU debug leds show all lights as a "go"
I wonder if it's even possible for the pin to become damaged while in usage for over a month and cause it to be stuck at A2 debug code? Having looked up the code it seems related to SATA,IDE and the likes which where not plugged in.
I was forced to buy the same motherboard from another store to actually use my pc again, the CPU itself is working fine so it's definitely the motherboard. Love the mobo, just not the store support
Needless to say, having spend 360 (180x2) euro on this board and receiving virtually no support from the shop, I'm not amused.
Any support or advice on this matter would be greatly appreciated.
Many thanks in advance,

ok have you asked to return the original board to the shop for RMA or a refund?
also did you have MSI live update installed when it all went bad?
I have returned the original board to the shop for RMA. They refused to accept it claiming MSI would not accept the board due to the slightly bend pin.
I did not have MSI live update installed at that time as I reformatted my pc recently so bare essentials were installed. I however do have it installed right now and used it update my new mobo to the latest bios firmware.

All you can do is try with each stick of ram alone in DIMM 2 w/ a barebones set-up. (Only ram, PSU, CPU & Cooler)
Re-seating the CPU may help but since this occurred when overclocking / changing bios settings w/ no physical adjustment it doesn't seem like that would help.
Assuming it doesn't work either way as recommended above, I would rma the CPU & mainboard at the same time. It's likely one or the other.

Z77 MPOWER - Debug code 55

Hi I just finished building my new rig with a mpower Z77 booted it and all the fans spin up but then on the debug LED it shows code 55 then just reboots and keeps cycling like that till i pull the power.
Anyone got any ideas?
Case : Fractal Design Define R4

VGA : MSI GTX 660 Ti Power Edition 2GB GDDR5

Got response from MSI this morning
Quote
For MSI bent socket pins aren’t a reason to declare the warranty void.
According to the serial number you sent me, your motherboard is still in warranty.
Please contact your reseller, Aria Technology, again to ask them to send your motherboard in for RMA Service, if necessary showing them this email.
If Aria Technology still won’t help you, please contact me again.
So have messaged Aria again, going to be interesting what they say.

Z77 Mpower boot issue - won't POST

Hi there
Got a question regarding a PC build that isn't working as well as hoped. Doing this on behalf of my friend but I've been helping him while he builds it so have a good idea of what's been going on.
Set up is as follows:
Processor: Core i5 3570k (stock, not overclocked or anything)
Motherboard: MSI Z77 Mpower
RAM: 8GB Corsair Vengeance memory (in 2x4gb)
PSU: Corsair 800W Gaming PSU
Storage: OCZ 240GB SSD
Cooling: Zalman water cooling (can't remember the exact model off hand I'm afraid, will try and get that later)
Graphics: HD 4000 integrated (for now, haven't got the graphics card yet)
We built the machine and got it going no problem. When it was first built it booted no problem, so we set up boot priorities and then installed the Windows 8 Enterprise 90 day trial. All good so far. Installed no problem at all at lightning speed and we got into Windows fine. Installed lots of drivers and so forth with no such trouble either. CPU was reporting a steady 25C average temperature on idle and everything seemed to be going smoothly.
Then we hit a stumbling block. We powered off the machine to make a minor adjustment in the case (all while static protected with a wristband), and after doing this we then powered the machine back on. We're now getting a dim red LED (almost seemed half powered) in the DrMOS overheat warning and then two bright blue LEDs next to it indicating the CPU power phase. The fans will spin and case LEDs come on, but nothing else happens other than that and the LEDs. No POST screen or anything like that. It might also be worth noting that now when you plug the computer in, the green LED on the internal power button no longer lights while the machine is off - when the machine was working it would.
I've spent hours trawling through the forums and can't seem to find the same problem happening. We're getting a bit worried that there could be a fault on the board but wondered if we could get some advice from here first. I tried resetting the CMOS with no avail and trying the other BIOS.
As a last resort, we've now removed the cooler and CPU to check the CPU hasn't melted or anything drastic like that and it's absolutely fine - no visible damage. We've left it like that for now until I can get back over there with some more thermal paste to reseat the processor and cooler so until then we're stuck anyway.
If anyone has any ideas or knows of the problem, it would be really appreciated as we're a bit worried! What should we try?
Thank you!

Many thanks, will give that a try. Is it an RMA to MSI if that fails then? Forgive me for not totally understanding consumer rights - but it was only bought around a week ago - could we get the supplier to exchange it or would it have to go to MSI for repair?
Quote from: xmad on 27-December-12, 05:16:31
Next, remove the main board and place it on a non-conductive surface and test it with a single stick of ram in dimm 2, cpu & cooler. You can try switching the ram ram sticks and dimms, but the last few times I saw anything about the drmos alarm it was a defective mainboard.
While it is out and the cpu is removed though, take a good look at the cpu socket pins and count all the stand off to make sure there are not extras.

Laptop will boot... backlight turns on... but no video signal

Hello!
(I searched but couldn't find a situation quite like mine, so sorry if this is a repost.)
After dropping my iBook, I busted the bezel/clutch. The unit powered up, including a fully functional display, but the lid just opened a little screwy.
So, I had the bezel/clutch replaced by an IT buddy, and when everything was reassembled, the unit would still boot up, the backlight would turn on, but there was no video signal! We thought maybe the VGA cable got messed up in the process, so we had it swapped out. Same problem.
Any ideas? Any thoughts if this problem is related to: http://discussions.apple.com/thread.jspa?threadID=877652&tstart=60 ?
I got a heck of a deal on this thing, so I'm thinking about just connecting to an ext. display, backing up everything, and parting it out on eBay. But this was my first Mac, and I only had it for a week, so if there's an easy/economical fix, I definitely want to give it a go!
Thanks folks!
Lance

Lactoes,
This is from Apple:
"Display
No display, or dim display, but computer appears to operate correctly
1. Remove any connected peripherals.
2. Try known-good power outlet, power adapter and power cord.
3. Press F2 (with the fn key pressed and not pressed) to increase the screen brightness
setting.
4. Reboot the computer—hold down the Control and Command keys and press the
Power button, or press and hold the Power button for 5 to 10 seconds to shut down the
computer, then press the Power button to restart.
5. Reset the power manager by pressing the key combination Control-Option-Shiftpower.
Warning: Make sure you do not hold down the "fn" key when resetting the
power manager.
Warning: Resetting the power manager means you will also need to reset the
date and time (using the Date & Time control panel).
6. Reset PRAM (Press the power button, then hold down the Option-Command-P-R
keys until you hear the startup chime at least one additional time after the initial
startup chime).
7. Verify backlight cable and LVDS cable connections are seated properly and that the
cables are not damaged (refer to display assembly replacement instructions).
8. Replace display.
9. Verify cable connections and check cables around the hinges for damage.
10. Replace logic board."
The LVDS cable:
922-6368
922-6432 (SS)
Check this out:

apparantly there were two versions of this cable the first and the ss.
Even so you should get something. Try the external monitor and report back.

[solved] No video signal on cold boot - replug power and all fine

Hi,
My issue is a cold boot one. 6 weeks ago I installed a new mobo with new CPU. Three weeks ago I installed new RAM. Spec follows.
Now, since yesterday, when cold booting the system after some time off, the fans start spinning but that's about it. No video signal. Keyboard dead (numlock off), nothing. Simple solution is to then unplug and replug the power cord and press boot again, which then starts the system normally.
I googled this post at techspot, which labels my problem straight-on but they are running ASUS mobos. Since my system worked fault-free before, I am critical to their solution. https://www.techspot.com/vb/all/windows/t-7148-No-signal-to-monitor-amp-no-post-beeps.html
Any ideas what to do? Thanks a lot for your replies!
MoBo: MSI Neo2-FR, BIOS: 1.9

PSU: Seasonic/ARCTIC, active PFC

but how come the problems came all the sudden
Well, they usually do, doesn't matter what component.
Try another Power Supply and see what happens. Than you will know if it is the PSU or not. (Maybe you have another system you can use the PSU from or a friend can borrow you his power supply unit.)

Z77 mpower debug code 62

hi everybody,
i have this motherboard for a few weeks now.and recently it will not boot, but give a error code 62 ,
fans will be spinning etc, but no post.
i have noticed loads of other users having this same issue from different websites, and i can not pin point the problem,
i still do not know what the error code means, as its not listed in the manual.
i am having this problem with intergrated graphics intel cpu. this happens when pc is switched off,not restart.its an intermitant issue,meaning it will work fine at times on boot,but not always,
i have to put pc off, and then it will boot up again fine. what is causing this issue on our z77 mpower boards ?
system specs :
no gpu ( using cpu gpraphics )
cpu i7 3770
mobo z77 mpower on bios version v17.11
psu seasonic 750w evo m12
2x 4 gigs ram
sata hard drives....
can anybody help ?

if the CPU is seated badly it can cause the issue if its not contacting the pins properly in the socket!
ok, but the cpu can only fit one way tightly in socket, there's no movement or looseness when inserted.
whats strange is that this is a problem experienced by many, just google z77 mpower error 62
thnx for advise btw but i think its something else though any advise would help. i will reseat tonight.

BOOT ORDER issue? MSI Z77 MPOWER + SSD Samsung 840pro

Hello
I have an MSI z77 MPower m/b - Intel i7/ 3770k and two hard disk drives...
First HHD (Samsung SSD 840PRO 256gb) connected on SATA Port 2.
Second HHD (WestedDigital WDC 2TB Green) connected on SATA Port 6.
The CDDVD is connected on Port 4.
The SSD has WIN7 .
The WDC 2TB, has 2 partitions. One with WIN8 and the other for BACKUP.
In the MSI BIOS under BOOT menu, i chose the HARD DISK DRIVE BBS Properties as shown :
Boot Option #1 Samsung SSD 840Pro
Boot Option #2 WDC WD20EARS-...
When I start my computer it usually boots on WIN7 from the SSD (1st choice).
The problem is that SOMETIMES after shutdown, the computers changes the BBS order and BOOTS on WIN8 from WDC.
When I re-enter on the BIOS the HARD DISK DRIVE BBS Properties is changed to:
Boot Option #1 WDC WD20EARS-...
Boot Option #2 Samsung SSD 840Pro
Can anyone help me with this boot issue?
Thanks,
Nikos

Other than updating the firmware of the SSD and mainboard: >> BIOSes<<
Use the disk management to make sure the boot partition of the WD drive isn't active.

MSI z77 mpower boot loop-cold start

Just got this PC put together a few days ago and I havent had luck keeping it at 4.5ghz @ 1.360v.
System Specs:
i5 2500k
z77 mpower @ latest bios version
16gb Corsair Vengeance 1866mhz
msi GTX 670 power edition oc
750w Corsair psu
256gb samsung SSD
Corsair H80
I can get it overclocked to 4.5ghz @ 1.360v and while running prime95 for 24hrs it was 100% stable, temps never went over 70C. I have set the I/O voltage to 1.2500v, the System Agent voltage to 1.105, the RAM memory voltage to 1.60v. XMP enabled @ 1866 9-10-9-27.
The problem is that it runs fine until I shut it down for 15 minutes then try to boot it back up, it boot loops 5-6 times then resets everything in the BIOS. The motherboard shows a code 60 as soon as it powers up, then it shuts down again, then powers back up then it gets stuck on A2, then again shuts down and starts back up and shows 60 again, and then A2 again, does this 5-6 times until it decides to reset everything and it allows me into BIOS again. It's driving me INSANE. Does anyone know what the heck is going on? I want to be able to shut it down when I go to sleep and be able to turn it back on without overclocking it again in the morning, ya know?
It works perfectly fine when I restart the computer, only happens when it sits turned off for more than 5 minutes.
Appreciate the help in advance.

We have similar boards and I cannot view your screen shots: https://forum-en.msi.com/index.php?topic=162043.0
Try an overclock based off mine and see if it is better.
If you want to do an muliplier change oc, post better screen shots so I can see what you have set.
**PS: Don't mimic my ram settings, just enable xmp. Also, you won't be able to get this stable at 1866 w/ 4 sticks unless you are lucky. Esp with a Sandy cpu.
Do your testing with just 2 sticks in dual channel, then put the 4 in and if you are lucky you may be able to set it to 1600 9-9-924 / 2t.

Mac Mini boot issue, chime, but no video signal.

Hello,
I'm repurposing an older MacMini for use as a home media server. The machine specs are as follows:
2.53mHz//2x2G/320/SD/AP/BT
I have:
1. Removed Airport/Bluetooth card -- they serve another purpose -- the unit will be hardwired to my LAN.
2. Upgraded HD to 500 GB, and installed Lion. Everything worked fine, I put the project on hold for a couple months to work on other things.
I went to install the unit on the wall the other day. Before I did I decided to power it on once more to check all was well before mounting it.
All of the connections appear to be fine, however... when I power the unit on, I hear the chime but never get any video signal. I've tried both:
VGA output using Mini-DVI to HDMI Adapter -- my existing Apple TV supports and this is how I got Lion Installed -- so I know the cables are good.
Worred that perhaps the Mini-DVI port was bad I also tried the:
Mini DisplayPort output with a VGA adapter, same result. I hear the chime and then nothing happens.
My next steop is to attempt to SSH into the Mini from anther machine. Before I go this route: Any ideas what I should be looking for or intermediate steps?
Any help would be appreciated.

I'd try the SSH and view the logs for last startup, or maybe Target Mode if SSH doesn't work.
