Hey all,
I've been slowly piecing together a brand new rig for myself ever since Christmas. The last thing to get replaced was my ATI Radeon 5770, which was showing some texture flickering and z-fighting in video games. I replaced it with a Diamond 6950 2gb which for some reason won't even start any sort of 3D application at all...unless I'm bit mining.
I first tried reinstalling drivers. I used driver sweeper in safe mode each time, and tried various different versions of the drivers. Whenever trying ANY sort of 3D app (usually furmark, but I tried games as well) I would immediately get a black screen with a slight amount of static and then I'd get sent back to my desktop with the message "The display driver has stopped responding and has recovered successfully." It plays flash videos and any other videos (including blu-ray quality videos) just fine.
I then formatted my disk, and completely reinstalled Windows. The first thing I did was install my chipset drivers and the video drivers...reboot...install Kombustor, and bam, same issue. Instant crashing to desktop with the "Display driver has stopped working" message. I did ensure that OpenGL/DirectX were both up to date.
So that should rule out driver issues.
I then remembered that I used to use GUIMiner, a Bit Mining program, to stress test my GPU's in the past. It works similarly to Prime95 (I think..don't quote me on it) and doesn't load any 3D display. It stresses the GPU very well, and I've always used it to test for proper cooling.
Anyhow, I started it up, and it was running perfectly. The card was mining at the rate that it should've been mining at. I think that this tells me that the GPU itself is fine, but I'm not 100% sure. Then I had the bright idea to start up Furmark while I was bit mining. It started up and ran perfectly, albeit only 90FPS. I stopped GUIMiner and it hopped up to 400 FPS. It worked fine for about 3-4 minutes until it began to incessantly crash the driver as it had been doing before, forcing me to end the process.
I tried loading games with GUIMiner running in the background, and they all loaded fine, though of course reduced performance since the GPU was being stressed by GUIminer. They would run fine until I stopped GUIminer. They'd run a *bit* better for 3-4 minutes until crashing incessantly to desktop until I ended the process.
With all of that being said, I think that I have it narrowed down to either my GPU or PSU.
I want advice as to which I should RMA. Right now the only thing I'm afraid of is RMA'ing one just to find out that the other is bad.
My PSU is a Corsair CX600 which I only bought a few weeks ago. From what I've been told (and what I've been reading), it's one of the crappiest Corsairs one can get....and I've read of similar issues happening with the exact same PSU and GPU. I tried using my 3 year old Antec Basiq 500W to see if there was any difference, but there was none. I tried unplugging my fans my other HDDs, my optical drives, and there was no noticeable difference. I tried downclocking the card, and undervolting it, but no noticeable difference. I even underclocked my CPU...no difference.
Other specs, in case they may be relevant:
8gb(2X4) of Corsair XMS3 RAM
Phenom II X4 960T OC'd to 3.9GHZ
Corsair CX600 PSU
WD Black 7200RPM 500GB HDD
Samsung "green" 5400 RPM 2TB HDD
Windows 7 x64
Gigabyte GA-78LMT-S2P Motherboard
Thanks for the help, and sorry if I'm a bit too wordy.
