Run a memory tester like memtest86 to see if you have bad RAM.=20

Keep a monitoring program like mbmon running in an xterm, to see if=20
1) the CPU or case temperature aren't too high, or
2) the voltages are low.

If (1) happens it could be caused by a broken or stuck fan or a plain
dirty heat exchanger, while (2) is probably indicating a power supply
which is short-circuiting or about to break down.=20

Sometimes cleaning the inside of the computer can sometime help with
these problems. Do remove the power cord when you do this, and don't
open up the power supply!
