Z68A-GD65 (B3) won't even enter bios

Well I got my MSI z68A-GD65 (B3) today.
The first time I set up the system I forgot to plug in the 8pin because I got confused with the (20 + 4)PIN stuff (I haven't had a PC for some years). After I sorted that out I got the system to start, it told me that "hardware and cpu had changed F1, F2 bla bla; so I pressed F1 to enter setup and have a look but it didn't do anything so I had to restart.
Right now I can only start the system, I will get somthing about marvell, and "no hard disk detected" (there is one plugged in without any windows), it will continue afterwards at the bottom there will appear DEL for Setup and F11 for bootmenu but neither of them will work.
So now I'm sitting here in front of my new computer I need to do some urgent work :S, but there is no way even to get to the setup.
I've tried to change the ram sticks (only one, with two,etc...) I've cleared the CMOS a thousand times, there is no way.
Do you have any clue of what to do?
My setup right now is
z68A-GD65 (B3)
i7 2600k
Corsair Vengeance 1600mhz 4x4=16gb 9-9-9-24 1.50V ver2.12

If I put the CPU in a bad way, would the thing actually start?
Not impossible. We have seen many a case of slightly bent socket pins, and then the pin does not make proper contact, which can have a myriad of side effects.
Take the CPU off, use a camera with macro facility if you got one, and take a high res picture to inspect the imprints on the CPU pads. A magnifying glass and bright light will also do.
Inspect the socket pins for any anomalies.

K8N Neo2 Odd behavior - Won't POST or reboot

I have been using this computer for years and recently sold it to a friend and now we're getting these odd problems. When the computer is first turned on, sometimes it won't power on (no fans or anything), however the power light flickers rapidly very dimly. After messing with it sometimes it will power on, but doesn't actually boot - just the fans and HDD come on. By pressing the power button on the front it will shut off and the power light will flash slowly (as though it was suspended). Pressing the power button again does not do anything.
After a lot of trial and error, I found that by holding in the power button while flipping the power switch in the back will cause the computer to turn on normally, but this is frustrating to do. Also, the computer won't reboot itself, it will get stuck in an infinite POST loop and requite to be turned off and then back on. It is not overclocked and I have reset the CMOS.

Oh dear looks like the Antec problems go back further than we thought.
bomax: I had very similar symptoms with a K8N Neo4 system recently. Check the main 20-pin power connector for pins which are pulling out of the plastic molding - seen that once on another system - and reseat it, but it's most likely the TruPower 380 that's gone bad - either the 5VSB or the power on latching is buggered.

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.

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.

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.

P67A-GD65[B3] Won't post

I get about 30 seconds of fans and power supply -- APS 1 LED lights, followed in 20 seconds by all six lighting and then the system shuts down. None of the BIOS LEDs illuminate. The power supply should be more than adequate Seasonic SS-850HT 850W. CPU is i7-2600K. Assistance appreciated

Please supply full system specs. >>Posting Guide<<

When experiencing problems, never exclude any component as being faulty. DOAs do occur.
You probably need to remove your MB from the case and place it on a non conducting surface, i.e. piece of wood or unprinted carton/cardboard.
Then test with only one RAM module and one HDD. bare minimum.

Z68A-GD65 G3 Reboot Loop

I'm putting together a new build and I've run into a reboot loop. When I attempt to start it up, it runs for about 5 seconds, then turns off. This goes on in an endless loop. It never gets to POST. The 6 LEDs light up and the BIOS ones don't (so this appear normal). I have never gotten a successful bootup.
My setup:
Motherboard: Z68A-GD65 G3
CPU: Intel Core i5, i5-2500K
Memory: Kingston HyperX (4x4GB DDR3 - 1600 CL9 240)
Power Supply: OCZ ZX Series 850W
CPU Cooling: Xigmatek Gaia SD1283
I am not listing anything else, because I am not getting far enough for it to matter.
I am running with only the above pieces connected to rule out all but the essentials.
I've inspected the CPU and slot. Both appear fine.
I've cleared the CMOS using the button on the I/O panel and removing the battery.
I've subbed out the Power Supply.
Only the 8 pin CPU and 24 pin motherboard connections are made.
I've tried various things with the RAM. All 4, just 2, and just 1 (in the DIMM1 slot). Most testing was done with just 1. I have tried all 4 in the DIMM1 slot.
I've removed it from the case and booted it up in the cardboard box (nonconducting) it came in, to rule out a short.
I've inspected the motherboard carefully, no obvious issues.
I've checked that the CPU cooler is making good contact with the CPU.
I've verified that the OC button is not active, although I've tried that too.
I've read through the forums, but have not been able to find a solution that works.
Please help. Thanks.

I had this very same problem with a Biostar T-POWER I55 2 years ago, to cut a story short the retailer and the distributor who handled Biostar RMA's rejected the RMA.
I spoke to Trading Standards/Consumer Direct as I read in the Sales Act that in the first 6 months of a purchase if the damage cannot be proven to be done by the end user then a warranty claim still exists.
Finally after stating this & quoting the Trading Standards Reference number to the retailer, I got a call from them saying they would offer a refurbished motherboard worth £113, my original motherboard cost £138 so I refused this & asked if they would agree if I could purchase a brand new alternative for (£75ish) around 50% of its purchase value to which after another day they rang back & agreed.
You are not the first and won't be the last this has happend too, One manufacturer will cover for warranty in these circumstances because I asked them.
I suppose you could get a 2 year warranty via Amazon, small expense for peace of mind which covers you for Accidental damage as well as mechanical failure, quite good if the motherboard pins snap off the motherboard.

MSI Z68A-GD65 won't start to bios!

gratz from Finland guys.
I have problem, heres my pack:
MSI z68a-gd65
i5 3450
hyperx predator 8gb 2x4gb rams
asus gtx660 pci-e 2gb
2tb seagate
650w corsair
and the problem, i installed up the components today and got it working first without detecting SATA 2tb seagate. Then i switched to all sata ports and the last one 8 and 7 worked fine for seagate and Asus DVD. But now the problem is that it lets me in marvell bios when it shows up the harddisk and dvd, but not in the "primary bios". When it shows the first data, harddisk and dvd, it goes straight to "Warning BIOS ME file not found install on the usb" etc... I dont know what to do because i read all the forums in the internet, wasted 6 hours in investigating internet and found nothing. Have tried the flash utilitys, USB flasher utility found in forums and all... Reseting BIOS didnt help.
Please help, im getting drunk every hour more with this cra*

Sdrastvui Svet, jeshli s toboj realno 4eres skaip pogovorit, skin poshalushta svoj nick tam.
As i know, the board was in the warranty fix, and became back to shop, where i buyed it. But the shop gave everyone who would buy the board, 6months warranty so i dont think it would be broken.
Also for the flashing, i dont have OS on that system, what we are talking about. And if i download those BIOS from the MSI site, its only EXE? I cant run exe from USB flash when starting PC?

Z68A-GD65 (G3) issues.

I'll start with my build,
Z68A-GD65 Gen 3
i5 2500k under Noctura NH-D14
16GB G.Skill DDR3 1333 CL9 1.5V
MSI R6950 Twin Frozr II 2GB
Crucial M4 128GB SSD (in 1st intel sata 3 port)
Antec HCP 850w
Bios 23.3 (or whatever, I'm on phone at work)
A few issues;
I can't OC. If I try an oc, it boots, I get splash screen for msi, then hangs with blinking underscore. Even if I match oc genie setting for setting in standard mode. Using auto etc, set v core way high (like 1.4 for a mild 4.2 oc) it just seems to hang. I'm guessing something to do with the sata 3 controller, since I'm booting off ssd
Last night I started PC, went to bathroom, came back and it was loop booting. I hard powered it off, and restarted. OC failed, and that was oc genie at 4.2.
PC won't wake up from sleep. Have to hard power off (hold power button down) then restart and it resumes windows. Mouse and two diff keyboards won't wake it (performance mx mouse, g510 keyboard, and ps2 dell keyboard.)
G510 won't enter bios, have to use dell ps2 keyboard.
If in OC genie, or trying oc in standard mode, system double posts. Starts, runs 4-5sec (no display), powers down, starts back up and runs fine for hours (except the one oc fail on genie)
Any ideas on any of it?

No, thats the last official release. There has been a host of beta BIOS releases since. I just flashed to the latest .N48 today and I must say, I am very happy with the stability I now have.
If you intend to flash, use the forum flasher. >>Use the MSI HQ Forum USB flasher<<
Do a full CMOS clear after flashing >>Clear CMOS Guide<<
Also you will need to ensure that you set your BIOS back to AHCI, if you did that before installing the OS.
I further suggest you remove all RAM except one stick in the slot closest to the CPU before the BIOS flash. Only put the other RAM back after you have been through one boot cycle.

Raid mode very slow/ crashing after installing driver (Z68A-GD65 (G3))

I recently purchased a Z68A-GD65 (G3) motherboard, i5-2500K, 8 gb ram, and a Crucial 64GB 4m SSD drive. The intention was to use the SSD drive for Intel Smart Response Tech.
Instructions tell me to place the SATA ports in RAID mode, which I did. During installation of Windows 7 (64-bit), I provided the "F6" raid drivers which installed. After that point, my hard drive (a WD 250GB SATAII drive) begins to perform incredibly slow. Once Windows 7 installs, which takes way longer than it should, Windows has problems booting and won't work properly.
I tried installing Windows 7 without the "F6" raid drive on install and that worked fine. Everything seemed to be working great. I then installed the Intel Rapid Storage Tech software and rebooted. Now my system is acting up again. It takes far longer to boot, it shuts down as soon as it boots, and it has even blue screened on boot. It is very unstable.
My SSD is unplugged during all of this. I'm just trying to get Windows 7 to run properly on my one mechanical drive in raid mode.
Do I have a bad motherboard? Anyone have any ideas?
Edit: I'm not using the Marvell ports. The hard drive works fine in IDE/ACHI modes... I've been using it for years.
Thanks

So it turned out that the issue was the hard drive itself. It had been running flawlessly for years as my system drive. However, the Intel iastor driver exposed a hidden issue with the drive.
I decided to check the Windows system event log for any clues. In there I saw errors with event id 9 on iastor. They were lined up with the times of the hangs and blue screens. Solutions I found online for this issue did not help. Luckily I have two hard drives in my system, although they are both the same model. I moved my data around and clean installed Windows on the other drive instead. The hangs and blue screens are no longer occurring.

Z68A-GD65 (G3) Memory problems after BIOS update

Good day, i'm russian, so sorry for my english.
Friend of mine had MSi Z68A-GD65 (G3), i5-2500K, memory pair 2*2GB with bios 22.8 (latest version with no red letters about ME8 and IvyBridge).
He decided to upgrade the processor to IvyBrydge and updated bios with new ME8. Then the computer went into a state of continue restarting every 3 seconds. After replacing the CPU to the new Ivy - computer works good, the impression is that the computer does not understand Sandy now and switched toIvy. But it has seen only one of memory pair. My friend just bought a new motherboard. Now he has no problems. I took his MB and SandyBridge CPU.
Flashing the bios to the old version by M-Flash - it does not see the BIOS file, although it is there (in the root, FAT, 2G). Flashed it under dos with AFUDE238 with a key -x, it said about mismatched ROM ID. After the old BIOS flashing (with an Ivy) computer went three-second reset mode. CPU changed to Sandy i5-2500K - now works good. By the way, now M-Flash see the firmware on a flash drive - I flashed it again from the M-Flash, just in case, reset the settings.
What is the problem: if I set the memory into the slot 3 or 4, the computer goes into a three-second reboot, it does not matter is the memory in the first two slots or no. If this memory is inserted in the first two slots - all ok. So I work now - in the first two slots with no dual-channel mode.
The feeling is that the problem appeared after first flashing to Ivy and remained after flashing back to Sandy.
Question 1: What to do to get working the memory slots?
Question 2: Is BIOS 22.8 - the latest which I will have with Sandy? (There is a problem now when the computer starts - 1 times out of 10 will not boot - reset is helping, and the BIOS at starting not very fast).
There are posts about people with the same MB and the CPU and the new BIOS (25.2) that supports Ivy. I'm confused. It means I can use the new firmware from SandyBridge. But there are many posts about problems with new firmware. Where is the true?
Just checked BIOS version - P.1 (25.1) 2012-04-16 - by the way with Ivy support. But I flashed with 22.8, I'm sure. ME version in BIOS isn't shown, but while booting - ME 7.0
What does it mean? Can it be repaired? What should I do?

Thanks to all. My system is working fine now.
What it was. I flashed BIOS with tool from this forum. Bios flashed good, but problem still was here. Then I flashed to the first bios version from support site. And again flashed ok but memory still not working in slots 3 and 4. Then I decided to flash back to last flash with Sandy support 22.8 (or 23.8). Then I flashed to the last bios at all - 25.4. Flashed it from dos - this was pretty long. It rebooted 3 times (ME updated too). I still don't know - what it was with first flashing to Ivy. Now it's ok.
So I decided the problem is bent pin. With magniglass and needle I've found some uncertain pins (these were not BENT, but slightly bent) and touched these with my needle. And that was the answer. Now all works fine. Thank you all.
On the russian msi forum no one answered and helped me at all.

Z68A-GD65 (G3) Component Advice

I am in the process of putting together my first PC and look like getting a Z68A-GD65 (G3) board.
The CPU will be a i5 2500K, but I would like some advice regarding ram and the CPU cooler. I intend just using the O/C button on the board method of over clocking as I am new to over clocking. I will be adding 8 gig system ram. What ram have people been using that causes no problems.
With regard to the CPU cooler I have read a few reviews where the bottom support bracket on the back of the board fouls with one on the board heat sink mounting screws. From the pictures one screw is close the the mounting hols.
The cooler I am thinking of is the Noctua NH-C12P, but it has quiet a big back plate. The other one I am looking at is the Cooler Master Hyper 212 EVO. I tend to like coolers that have back plates and screws to mount them rather than push pins as they are easier to reuse and mount firmly.
Are these coolers good enough for my overclocking needs. I hope the auto overclock will give me just over 4 gig which will be fine for me.
For the case I will use a HAF X or a Corsair model, should have enough airflow.
So what ram have people used with this board that overclocks well and does not cause reboots during the overclocking process, and of course the CPU cooler.
This is my first full build, and first go at overclocking so I am looking at compatibility and reliability over performance, and I do not need a big overclock for my needs. This is a build mainly for FSX flight simulator.
Also from reading some posts here I will need to flash the BIOS as well. The process described here to flash the BIOS seems complicated to what I have done in the past which has been on gigabyte boards only. I used to just download a small exe and run it from within windows. Is that possible with this board as I do not understand the process from what I have read here in the forums?
I presume my choice of mother board from the MSI range is right from my needs, if not please recommend what I should be using.
Any advice will be appreciated.
Regards MarkL

Zalman 9900 series. Copper version up to the Max-B. Superior cooling ability. No blocked dimm slots & no mount hole problems. As for RAM, Corsair GT's, Vengeance, or Dominators are my brand of choice. DDR3 1333 is the platforms CPU IMC native supported RAM speed, & testing has proved RAM speed above 1600 is mostly a waste of time & money for a gaming rig, with only a slight performance gain when rendering. The most trouble free RAM will be kits that properly default to the 1333 speed. X.M.P. can be used, or manual settings above 1333 can be tried.
That choice of mainboard should serve your requirement quite nicely.
I have a question about the memory. I have been looking at the Corsair Vengeance range that I can buy online in Australia and they all seem to be 1600 not 1333.
PC Case Gear seems to have the best range, but they are inconsistent in the way they give the specs, at least to my understanding which is next to nothing.
http://www.pccasegear.com/index.php?main_page=index&cPath=186_218_1125
The closest I can see is the "Corsair Vengeance CML16GX3M4A1600C9 16GB (4x4GB) DDR3" kit.
This kit has a SPD speed of 1333, speed rating of PC3 12800 (1600 MHz) and a tested speed of 1600. Voltage is 1.5v
Is the SPD rating the most important? If the SPD is 1333 is this the memories real speed?
Most of the memory they do not give the XPD speed but mention it has a XMP profile for overclocking.
Very confusing. I must admit that in the past I have just purchased the value range when upgrading and have had no idea what I have really purchased.
The Dominators are out of my price range but all seem to be much higher specked than the vengeance series.
Is the "Corsair Vengeance CML16GX3M4A1600C9 16GB (4x4GB) DDR3" kit OK for my needs?
One thing building your own PC, you start to learn a little more and realise the value of forums like these and how little you really know.

Unboxing MSI's Mainstream Z68A-GD65 Motherboard

After the release of the Z68A-GD80 model, MSI has launched another Z68 for the mainstream segment named “Z68A-GD65”. Below is a short comparison of the GD65 against the GD80.
Z68A-GD80   /   Z68A-GD65
Firewire         1         N/A
e-SATA         1         N/A
Gigabit LAN        2         1
PCIEx16 Slots      3 (8/8/4)      2 (8/8)
Chipset Heatsinks    Better      Smaller
For the motherboard features, both are identical. Super Charger (charge USB mobile devices even if your PC is turned off), DrMOS (Driver in MOSFET which was been copied by G brand already), Military Class II Components, Active Phase Switching (hardware based energy saving), THX Studio Pro Audio, Click Bios and V-Check Points.
Packaging
• L Shaped SATA Cables
• SATA Power
•Manuals and Software DVD
•SLI Bridge Cable
•V-Check Points Connector and Header Guide
•USB 3.0 PCI Bracket and Backplate
Next, actual shots of the board.
Clean layout and sturdy looking components.
Color Red Header is for the SuperCharger feature of the board. You will also find the dual bios chips located on top of that.
Big room for large Pots if you are into extreme overclocking and you won’t have a hard time putting insulations around the socket area. You will also find the OC Genie button near the 24pin-power which I find it weird for placing it here and not with the Easy Buttons
Easy Power and Reset Buttons
Lastly, IO Rear Terminal Connections
That’s it. Thank guys

Gzhil, thanks for posting this.
If you have time, do you think you could please test the Virtu Switchable Graphics functionality and post power consumption readings? I'd find it very interesting to see how effective the technology is.

MSI Z68A-GD65 (G3) 99.8MHz bug, temporary fix to make it 100MHz

With the current available official and beta bios, when disabling spread spectrum, the bus speed does not increase from 99.8MHz to 100MHz, I have messaged MSI support again to look into this with the current 23.4B4 Beta Bios.
Anyway I have found a fix for this, download the latest Control Center v2.2.0036 off the MSI website.
If your CPU Base Frequency is at default in bios 10000 you will see 98.8MHz on CPU-Z so in Control Center change the Base Clock (MHz) to 100.2 MHz and click save.
If your CPU Base Frequency is at 10010 you will see 100.2MHz on CPU-Z so in Control Center change the Base Clock (MHz) to 100MHz and click save.
Either way when you reboot it will always show 100MHz.

Thanks for posting this, and creating the thread, Nelly
I just use the 10010 bclk bios setting, but that band-aid solution doesn't net an even 100.0MHz.
My earlier attempts at contacting support about the 98.8 issue just get the generic "disable spread spectrum" reply. Some of the earlier bios for my previous MSI P67-G43 board gave me the correct 100MHz bus speed for that board, but it also changed to 98.8 with the later bios releases.
But even the "first" "00" bios for the Z68A-GD65 G3 has the 98.8 flaw, as does every single bios that MSI has issued for this board, beta or otherwise, since.

Granted you might get away with it. But the next person that reads this & uses that for everyday may not be so lucky. If games, applications, programs, & whatever else can't be done on what 1.400v's can provide for a decent performance level, the rest is just for show. That 'is not' a low low voltage for a 4.8. One of the test rigs here & a 2600k will do 4.8 on only 1.392v's with 4 cores & 8 threads & never miss a beat. If really serious about everyday maximum performance on 'real' low low voltage, get a 2700k!
Rather impressive voltage for 4.9 with that 2700K
It takes 1.390v. in the bios for my 2500K to do a 12hr. P95 run with no errors, at a much lower 4.6GHz.

Z68A-GD65 G3 No video on GPU, IGD works fine

Hello everyone. I'm making a post on a recent board, mainly the MSI Z68A-GD65 G3, that I've received from a previous RMA due to bad pins. This one boots up normally just fine when plugged into VGA, DVI, and HDMI directly and able to use Windows with no problem. So I use my EVGA GTX 750 that I saved up for the new MB However, once I try to install my gpu and power it up it doesn't show any sign of post nor boot screen avail. I've updated the bios to the beta from .80 to .93, cleared cmos, and tried installing Intel ME8 afterwards from reading other posts with the same issues. Yet, after some of the suggestions that I've tried out it still shows a blank screen with no post code nor progress whatsoever. I switched the GPU around to the second PCIe slot and tried out my older GTS 250 ones as well, no dice. Is there anything that I'm doing wrong or any alternative that I can try to make it show?
Board: MSI Z68A-GD65 G3
Bios: Version: 25.93B
VGA: EVGA GTX 750
PSU: Corsair TX850W
CPU: Intel i5 2500 3.30 GHz
Mem: 8GB 2x4 Kingston PC3-8500 DIMM 1066 MHz DDR3
HDD: Western Digital 1TB
CPU Fan: Intel i5-2500 Processor Fan
OS: Windows 7 x64 Ultimate
Any help is greatly appreciated.

GTS 250 also shows a blank screen with no post code?
Did you attach the PCI-E power cable, and update the vbios?
PCI-E cables are connected to it since the GTS 250 requires them, but the 750 doesn't. So they do run fine when I tested them out once more on my old EVGA motherboard. Not sure how to update the vbios, but that sounds like a good idea to give it a shot.

Id this the first time you try VGA card in it since it was RMAd?
If it is I suggest you take it back with them.
Well the GTX 750 was recently bought brand new and I tested it out on my previous motherboard along with a friends system as well. It showed up properly with no problem. The z68a motherboard was the one I had to RMA because of broken pins on the CPU slot that gave me an infinite boot loop. Even when plugged into the system and using the onboard graphics, it seems that the board doesn't even detect it in the device manager. I do see 'Unknown Device' in it, but it doesn't exactly tell if its for the VGA card or something else.
