Geforce Corruption and Crash

[calzakk]

Hi guys,

I've just upgraded from a GF 5200 to a 7600GT, but on certain games (Eve Online, Doom 3) and Google Earth I'm having some corruption of bitmaps, strange visible white rectangles, and even crashing. (My PC specs: Athlon XP 3000 Barton 333KHz FSB, 1GB PC2700, AGP 8x, EPOX EP-8RDA3+ mobo.)

I've tried installing all possible forceware drivers (latest, latest beta, and older versions too), making sure I always uninstall the existing drivers then rebooting beforehand. I've changed the AGP aperture size, trying values between 64MB and 512MB. I've tried disabling AGP fast write. I've tried disabling anti-aliasing, anisotropic filtering, in fact everything. Even underclocking and overclocking. All to no avail

What I haven't done is change the power supply. I've got a Silentium T1 case with fixed Seasonic 350W continuous (thus I cannot easily change the PSU). I've got one HDD, one DVD-RW, an Audigy 2, a few additional low power 8cm fans, so 350W should be sufficient. I haven't also retried reinstalling Windows XP (Pro, SP2), that's a last resort. As far as I see it, the problem's being caused by either of these, or my Epox mobo.

I originally bought a 6800GT, which gave me the exact same problems, but returned it 'cos I thought it was faulty (which obviously it wasn't!).

Thanks for any help in advance

what about chipset drivers, you updated them?
looks a mobo/psu problem, cant see it as xp problem. best bet is to try another mobo first.

Thanks mercyless - but I forgot to mention that I've got the latest bios and chipset drivers.

Sounds like PSU to me.

I had an old system which I tried to update, and put an AGP card in it. I think it was an Nvidia 6200. Anywho, fired up Doom3 and NFS:U and the textures were all messed up. Windows was working fine though. I took it back to the shop and went "I think this card is broken" but they tested it for me and let me watch on the test rig. They fired up Doom3 and it was fine. They asked about the PSU and I said it was some Generic 300W thing and bingo, they said that needs to be changed.

Of course I didn't as it wasn't worth the money so I sold the system for spares.

But that could be the same thing here....
