You will need to open up the case and take a look at the motherboard. You are looking for bad capacitors. Also your model Dell has a known issue, the power supply fan is crappy and has a high failure rate. So take the side off of it and power it on and take a look at the power supply fan.

See here for examples of bad caps.

already checked for capacitor leaks, all seem normal....will double check the power supply fan. prior to this condition, the fan for the heat sink was accelerating at times. I recoated the heat since with silver paste. if the computer boots normally and then fails, can the cpu act that way. work properly and still fail after a few minutes?

yes it can also if the paste is not applied correctly

This is what dell says, of course it is utterly useless, but you may want to reseat all the cable in the computer.

Ensure that the cables are properly connected to the system board from the hard drive, CD drive, and DVD drive.
Check the computer message that appears on your monitor screen.
If the problem persists, contact Dell.

With dell saying that you need to check the cables, it sounds like it is some sort of IO error. This leads me to think that your hard drive maybe spinning down do to a lack of power. You may want to take you power supply out, open it up, unplugged of course, and have a look at the caps in there.

Question: Is this the slim or the micro form factor case? If it is the micro then have get a multimeter and check the resistance of the ceramic capacitors on the motherboard between the front fan and the CPU. These caps are known to fail on these dells. By the way you should get no resistance. You only have to measure one of them as they are in parallel.

Tried using the XP master cd to start the computer. would not boot.....tried over 20 times, ...the machine finally started to boot. i erased the error log, ..then closed the setup....the computer continued to boot.
the software indicated it had just recovered from a serious fault...works normally now, have no idea why but the continual booting tries over time must have done something to the hard drive. it all works normally now.
