I recently built a new computer:
CPU: Intel E8400 Core 2 Duo 3.0GHz
Motherboard: Gigabyte GA-EP35-DS3L
Memory: G. Skill 4GB DDR2 800
Video Card: EVGA 8800GT 512MB video card
Power Supply: Corsair 520HX
Hard Drive: Western Digital WD6400AAKS 640GB
CDROM: Samsung SH-S203B
Case: Antec 900
Everything was fine for about a week. I use it to surf internet and play EQ and WoW. Then, one night after a few hours, Everquest locked up. Screen looked fine, no artifacts. Whole computer locked up. Cold not alt-tab out, or ctrl-alt-del. Had to reset computer. Then worked fine. Did e same thing next few days. Then, I got artifacts the next time. Recently, it will do it almost immediately, and almost totally blank the screen. No errors come up that I can find. I did get NV4_Disp error twice. Here is what I have tried to remedy it to no avail:
1. Tried 5 different video drivers, from latest all the way back to almost a year ago. Uninstalled/Installed in safe mode and used Driver Cleaner Pro each time. Did not fix problem.
2. Have most up to date motherboard bios. Tried F4, and even F5c(Beta) and both did not fix it.
3. Ran Prime95 for 2-3 hours on Torture Test 2-3 different times. It did not report any errors.
4. Ran Memtest86+ V 2.01 for 3-5 passes and 3-5 hours. No Errors.
5. Temps on CPU are fine
6. GPU temps on card are fine.
7. Set GPU fan to 75-100% to no avail.
8. Installed side 120mm fan. Still locks up.
9. Ran ATI Tool Artifact test. Temps were fine, but after 30 seconds it would artifact.
10. Cut GPU clock, shader clock, and memory clock from 50-200 each to underclock card, and still locks up and artifacts in ATI Tool.
So............I am down to the card being bad or the power supply. As stated before, everything is brand new. From what I can tell, sounds like the memory on video card is bad, and I am considering RMAing it. But, came to my attention it could be power supply. Just as a side note, I have and APC UPS Backup(XS1500LCD). LCD display says under load when playing EQ it draws 150-200W. Is this to be a concern? I would have thought it would be more...........is this a sign PSU might be bad? Or, do all signs point to Video Card?
If I have missed anything or need to do another test, please let me know, or what people think my problem is. Everything is under warranty....I just don't want to RMA a component without being sure that is problem, and get it and it does same thing. Have I missed anything?
I do have another computer. I have not tried to swap the video card into it. Might try that tonight, unless what Ihave stated is obvious that it is the PSU or Video Card is defective.
Please Advise.....................
