Having problems with Nvidia drivers, any ideas?

Hi there,
I recently set up a system as follows:

Asus P4P800 VM
2.4g P4
512meg PC3200 - 1 stick
Geforce 4 Ti 4600 (53.03 drvrs)
SB Audigy 2
Win XP home, clean install

The video and sound cards used to live on an Abit BH6 board and ran fine for 3+ /- years w/ a PIII 700.

After upgrading and installing a clean Win XP home, I'm getting random failures. Usually it's a graphics degradation with odd colors, lines or other artifacts followed by a freeze and re-boot. Sometimes after the re-boot I will get a message that the failure was due to the vid drivers or the card failed to draw. I have latest mobo BIOS, tried different Nvidia drivers, same random results. Tonight it's been rock steady for hours, last night I was re-booting every 20 minutes. This was occuring both before and after a clean re-install of XP. I've gone back to the original drivers supplied with the card, and they seem to be stable, not enough time on them yet to be sure.

Any ideas or similar experiences on this one?

Thanks

I use that version of the driver myself, its stable. Could be a hardware problem. Overheating, dodgy PSU or something of that nature. Try running with the case off and make sur theres cold air going in, see if that stabilises it.

REV 53.03 was written specifically for the FX cards, and have been known to cause problems with older cards. Unless you have a specific reason to update, I'd suggest running the 52.16 drivers on cards older than the FX. You gain no benefits to running newer drivers.

Thanks, guys.
I've opened the case ad added two fans, one on the card and one on the cpu, the cpu is showing 97F now, so that should be o.k. o temp monitor for the card, but it feels cool.
I wasn't sure where the driver cutoff was between new & old gpu's, so that could help. I'll run it back to 52.16 and see what happens. I hope it's not hardware, I don't really have the money to spend on a new card. Then again, that would provide an excuse to get a new toy.
