ATI drivers uninstall every restart

[Austempest]

Hey all,

ive just bought a new pc and all was working fine for about two weeks, untill about 5 days ago.

For some strange reason every time i restart the PC, it keeps uninstalling the ATI graphics card drivers. Well its not really uninstalling its just saying it cant use them. See screen shot of the desktop straight after start up. And yes, it reverts to 640*480 res and 8 colors.



I've downloaded the new drivers off the ATI website. The main thing that confuses me is that it worked fine for about two weeks, then pooof.

Every time it happened, i had to re-install the drivers and restart and it booted up normally, then next time it reset it screwed up again.

So ive just not turned off my pc for 4 days now.

My system is:
AMD Phenom 9750 Quad Core (AM2) 2.4GHz
Gigabyte GA-MA78G-DS3H Mainboard
Pioneer DVR-215 SATA DVD Re-Writer (20x/10x Dual Layer Black)
Corsair DDR2 4GB PC-6400/800 (2xXMS2 2GB) T
Card Reader 8 in 1 Internal USB - Black
Asus EAH3870X2-3DHTI-1G RADEON 3870X2,
Antec Nine Hundred Black Ultimate Gamer Case (No PSU)
Zalman 850W Dual Heatpipe ATX Power Supply (ZM850-HP)

Running XP SP3

Any Ideas?

Look for newer 3870X2 drivers if you can. Possibly from your card manufacturers website or go to the Ati site instead.

were you using catalyst 8.6 or 8.5 if you were using 8.6 and it was locking up go back to 8.5 and see if thats stable.

That's happened a few times with my two 3870's...

uninstall the card(s) in device manager, use driver cleaner to remove the rest of the ATI drivers, then install just the drivers.
Then, download CCC (separate installer) and install it from that

do you know what was actually causing this problem? sounds like it could be the transition between old and new drivers/CCC, because whne all is removed it works agen.
