6950 crossfire suddenly turned into a nightmare.

post #1 of 5
Thread Starter 
Hello, I recently had to do a clean reinstall of windows on my system as I had a failed OCZ synapse SSD installed that corrupted my HDD. Everything went fine, and everything has seemed fine since then, until now. When I tried to launch crysis 2 and play it, I got a BSOD about 20 min in. I Had the 12.2 drivers installed with the CAP 1. Actually, when I tried to update to these drivers on my last windows uninstall my computer had a BSOD and my windows became unbootable, which also managed to make my synapse fail. I read up on it afterward and found many people were having BSOD while installing and while using these drivers. My problem is I rolled back to the 12.2 preview drivers and the 12.1 CAP 3, and I am still receiving the BSODs, in BF3 also. I'm currently testing my RAM while I am at work. If anyone has possible solutions to my problem or is having similar issues, please share.

Edit: my system specs -
Motherboard: P67A-GD65 B3
CPU: 2600k @ 4.2 GHz
RAM: G.Skill Ripjaws X 8GB @ 1600MHz
PSU: HX 750
STORAGE: 1TB WD Caviar Black, with 64GB OCZ Synapse

You should try with only one card in, test everything and see if you BSOD. Then test the other card, I am stating this as it sound more like a hardware issue on the BSOD. Trying the cards 1 at a time you can see if one of them is the problem.

Ok guys I found the problem.... one that you might not have expected haha. So, I ran memtest for about 10 hours without a single error. The ram is just fine. Then I gave my drivers one last rollback to 12.1a just too see if it would make a difference. I was still crashing, I remembered that the bsod pointed to kbdclass.sys which is the keyboard. I remember my motherboard had issues with the logitech gaming series keyboards, and I had to use the legacy drivers. So I decided to update my keyboards drivers, to no avail. So, finally I realized that everytime I would crash I would be trying to switch my weapon with my razer nagas number keys. So I uninstalled the new drivers (the synapse 2.0 drivers) and found that it stopped happening. So my guess is that either their is a conflict between amd drivers or there's a compatibility issue withe that driver and my motherboard (msi P67A-GD65 B3). Can someone test this further to verify these observations possibly? Thanks for the help guys, I'm pretty relieved I haven't had to make another rma, ive had plenty of problems with this build already (2 faulty corsair psus, faulty fan on a previous 6950, and a faulty ocz synapse).
