Re: Power Supply?

[John Jones <chianime@xxxxxxxxx>]

Possibilities in the order I'd try:
1. Loose connection somewhere (power cable, cables from PSU to
motherboard).  Tighten up or unplug/replug the connections.
2. Dust somewhere.  Use a can of compressed air & blow the dust out.  Hit
all vents & fans and make sure you blow out the PSU as well as the CPU/case
fans.  Also blow out any heat sinks.  You might want to take the PC outside
for this step.
3. Power supply. Swap in a known-good one.
3. Motherboard.  Examine the board for scorch marks.  Examine capacitors for
bulges/leaks.  Replace
4. CPU.  Examine/replace thermal compound between CPU & heat sink.

If you get to items 3/4 and you have to buy a replacement board or CPU,
consider upgrading to a current gen CPU (i3/i5/i7 for Intel, for instance).
Current CPUs should be faster while consuming a little less power.

Just about anything else and you'd get a BIOS beep code to indicate the
error.
