I don't think that it is any fault on the motherboard. I have the same problems and reading all the posts its a driver problem. Since Robert_U closed down a post on this subject on august 9, there is no response anymore from Intel on this subject. It is not clear if Intel is still working on the subject; disappointing. Hope that Robert_U can tell us a little bit more.
I send my board back to the retail seller, who tested the board. Got it back, the board is working correctly acc. their tests. I specifically asked if they loaded all the drivers; they told me they did. They claim that it could also my monitor or TV, which causes the problem. I very much doubt that now, but can not exclude this. Anyway, if you sent the board back be sure to make a clear agreement how they will test it; better still, be present during testing if possible.
I ve likely the same problem with mij i5 2500k on a GA-Z68X-UD3H-B3 Motherboard. I ve installed w7 and al the drivers many times this week but the system became very unstable after installing the video driver. He random restarts without warnings or BSOD. Im running the latest bios (f8) and the latest firmware for mij SSD Agility 3 (2.11).
With the W7 VGA-driver the system is working ok. I now will try an PCIe videocard to see what happens.
I ve tried everything for a week now. (I build the system a week ago with all new components) Sleepless nights. Now i ve installed my old Geforce 8600GTS and the system works perfectly. I m running burn in test for one hour now and nothings stops the system anymore.
But i ve designed my system to work with the onboard video. I dont know what to do. RMA or better drivers?
Proc. : i5 2500K
Cooler: Shuriken Rev B
Mem: Corsair Vegeance memory
SSD: Agility 3
HDD: WD 320 GB
PSU : Zalman 500-HP
Case: CM Enforcer Storm
I ll wait for the real solution.
Is the Intel driver active or did you have to disable it?
Indeed it could be the GPU. But how can you check that. I don't have spare processors laying around. Is there a piece of software which one can run? On the otherhand, when I disable all video drivers, remove the separate video card and run the system with the standard windows video driver, it works. Is the GPU in such a case not operating? Is the CPU part of the processor than taken care of the video?
I was able to reproduce the problem to the tech at Fry's Electronics. We swapped the CPU with another NIB Core i5 2500K with the same results. I brought my own HDD with a completely updated Windows 7 install sans video driver (using the Standard VGA driver). The tech installed the video driver, and on the next reboot - black screen with a movable mouse cursor.
He convinced me to buy a different board (the Gigabyte board I bought was the last one), and I chose a comparable Asus for $30 more. Of course, they wanted another $10 to do tests at the bench, so I decided to return everything. The deal just didn't turn out to be a deal after paying for two tests and the $30 price difference.
I'll wait until Intel gets their act together before I decide on going forward with this project.
Thanks for all the similar stories. Good to know I'm not alone.
With my old Geforce Card all is working well. But now i ve the onboard enabled again and init it first in BIOS. The Intel-driver installs automatic and the onboard works stable for the first time in a week of many many installs. De Geforce is running as well but i plugged in at the onboard video.
Can someone explain whats happening?
What do you mean by : init it first in the BIOS. The Onboard VGA is set to "auto" in my case. The other two settings are" Always enable" and "Enable if ext PEG". Which setting are you using?
Could you desribe exactly in which order you proceed. It looks like that you first removed the Intel driver completely, than set someting in the BIOS, bootup and the Intel driver loaded itself? Which version of the Intel driver is installed?
Did you load the latest BIOS version as well?
If I know how you did it, I can try it with my board as well. I have in principle the same board, only with an intergrated SSD ( Z68XP-UD3-iSSD)
I ve the latest bios F8 in my case.
I set back de vga driver (comes with windows) to run without problems with the onboard video.
I installed de Geforce and set the onboard vga tot Enable If No Ext PEG and set de BIOS option 'Init display first' to PCIE x16. After rebooting windows installed the drivers for the geforce and it works fine.
After this i changed the 2 bios values to resp. Always enable and Onboard. Change from output connector to the onboard and start up again. Windows installs the Intel driver (maybe after update) and the onboards works.
I realy don't know why but for me its working now.
I'm such a sucker for the Sandy Bridge. After seeing the low power consumption, I couldn't sleep knowing that awesome was only another trial away. I bought myself an ASRock Z68 Pro3-M and another Core i5 2500K, this time from Microcenter. I bought memory from Newegg this time, but since I can't wait, I'm borrowing some DDR3 from a friend so I could give it another go.
Will report back my findings. I'll even see if I can replicate your process with this mobo.
