OK .... probably my fault anyway ..... but ..... I cleaned up inside my tower ..... lots of fluff dust etc .

Now I have a major problem ..... first I had no power at all, then power but everything was flashing so I unplugged it. Then eventually after many attempts I got it booted ... it reset the bios? and then after several hours of running perfectly it crashed and the power supply started messing up again.

I can see and hear both the cpu and power supply fans working .... but could this be overheating? What should I check and what should I take note of in the meantime that would help diagnose the fault?

Pentium III 650, 250ram nothing special in there at all
