PC will not fold now?

[oceaness]

I have a PC here that has been folding at stock speeds for ages and now all of a sudden it's started crashing when Fah is running. It's still at stock.

Temps seems to be ok. It's an Athlon XP 1800 I think or something similar. I Can get exact CPU details if it's relevant.

One thing I have noticed is that when I stop the Fah service, task manager shows System Idle Process @ 99% however the task manager graph actually shows it jumping around above 50% and Speedfan also shows between 60 and 70% CPU usage.

Any ideas?

The machine is clean. No dust.

I think it's probably general stability cause theres clearly something wrong even when folding isn't running. It just happens to be the only CPU intensive program thats ever run on it so it just looks like it's that thats causing it to crash, but I don't think it is.

I suppose there could be something on there that shouldn't be.

Will start a scan.

If I can't find anything then I'll probably just reformat it.

Thanks

Did you try sp2004/prime?

That should tell you if its a software problem or some flaky hardware on its last legs.

Edit: Happens to the best of us i suppose. My turn for some problems. This hardware must have been working for at least a month now, new it couldn't last.

I haven't run Prime or sp2004 it crashes when playing videos lol let alone anything more CPU intentsive

If it's that old it may just be that - old. I'm worried about my XP1700 board doing the same as it's already given me some PCI bus grief when I re-cased it earlier this year.

/starts saving for a C2D board to go in my Linux server.

Yeah but I thought processors generally lasted longer when not overclocked. It's not that old probably 5 or 6 years at the most.

Right lol looks like I've got quite a bit to be getting on with

I'll run through everything you guys have suggested, thanks for the many replies.

I'll let you know the outcome
