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?
