Re: Power Supply?

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.

All,

My son's desktop PC (built by a local shop a couple of years ago) started
acting up Friday night. Most of the time it won't come on at all, once

in

a
while it will boot up. When it _doesn't_ come on, nothing comes on.
Nothing on the display, no hard drive light, no power light.

My first thought was power supply, but even when nothing else comes on,

the

fan in the power supply runs.

Have you ever heard of that? Power supply goes, but the fan still runs?

Thanks.
