New Vid Card = Bluescreen blues
I've got an old system that has been running perfectly stable with an fx5200 (woo hoo!) for years. I finally ponied up to put a decent AGP video card in it so I could play games like Oblivion again. I bought a refurbished card from E-bay, and I think I got a dud, but it may not be the card.
Before installing the new x800pro I ran 3dmark01, 03, 05, and 06 on my fx5200 and it ran all four tests (didn't score too much, but it ran). With the new card, 3dmark03 bluescreens as soon as it loads the second graphics test. 3dmark01 bluescreens somewhere in the middle of the nature test each time. 3dmark05 and 06, however, run perfectly fine and give me a pretty nice score.
When it "bluescreens" there is no test on the screen, just a pure blue screen for 2-3 seconds and then the system reboots. Each time I get back into windows I get a "System has recovered from a serious error" message.
So, I'm at a loss. Also, I can play Morrowind for an hour with no problems. If I try to play Oblivion, though, it runs for 1 second to 1 minute before I get another bluescreen/reboot.
Here's what I've done:
-Tried different power connector and even unhooked extra hard drive, cd drive, fans, etc., from my PSU.
-Removed two PCI cards.
-uninstalled all drivers from ATI and Nvidia, re-installed ATI drivers only.
-tried older version of ATI drivers.
-run a memory test on the video card ram (it passed)
-Used ATI tool to stress out the GPU. The card gets up to 70C but it runs stable. I used this to log the GPU temp and when it is bluescreening it can be as low as 45C.
-I have not O/C'd the card, but tried underclocking it a bit, which didn't help.
-Disabled system reboot upon system error in WinXP. Now, I just get a blank blue screen that never disappears.
Any input would be greatly appreciated. Thanks!
