Continued system lock-up, even after re-install

[Clockworks]

A few days ago, my rig started slowing down and it usually started to lockup after a given time. I thought it was over heating as it never lockup in the past 2 years. I cleaned up the insides and thought the problem would go away. It didn't. I then assumed there must've been something wrong with windows so I re-installed it (XP SP2). Booted up fine, installed all the drivers, and it continues to do the same thing as before. Facts:

- System is at 40C idle and 48C load.
- HD is always being acessed and it doesn't stop (no spyware, nor viruses)
- Drivers are up-do-date
- Locks up at any game that I try to play
- Ran Memtest86+ and nothing came up


Machine is a:

- Sempron 3100+
- 1 Gig RAM
- 9800Pro ATI brand
- 160 SATA HD Seagate
- Nforce 3 250Gb board
- NeoPower 480W

Help?

hmmm...well...one thing id check is to make sure the bios settings you have been using are still set right....your cmos battery may be going bad and changing settings.
other than that...its possible you have a piece of hardware thats failing.....problems like this can make a person kill someone...and when u dont have any other hardware to test with...then u want to kill 7 ppl

The CMOS is fine, I installed a new one a few weeks ago and the PC has been one all the tme so it couldn't have been drained that fast. You are right, it is something with the hardware and to make everything worse, I can't swap hardware as I don't have anything to swap with.

Have you checked to see if the system is prime95 stable? use the blend mode to test.

are you able to run RTHDRIBL without the system crashing?

what about both at the same time?

I'm guessing it's something thats being brought on by the new summer temps, but we'll see.

I checked it out and it was an automatic lock. Assuming it was the Vid card itself, I exchanged it for a spare Nvidia card. All the problems went away. So right now this is down to either the card itself or the new drivers. I'll check tmorrow.
