PC will bootup to XP. Within a few seconds or up to a few minutes, the signal to the monitor is gone, and the cpu fan shuts down. The power supply is still running and so is the HDD. The HDD is spinning (but I don't hear any read/write activity. If I boot into safe mode the system will do just fine. I used it for 3.5 hrs with no issues. Here's what I have tried to this point:
1. Ran intense diagnostics on HDD, RAM, CPU and video card with no errors or failures
2. Tried a non-destruction recovery
3. Complete destructive recovery
4. New power supply
5. new video card

Same results.

the system:
HP Pavilion tower 752c
512 MB RAM
P4 2.0 GHz
Intel onboard video/graphic

it is probably a driver issue; try updating your drivers in safe mode.
a system restore can help too

It won't make it thru a Windows restore w/o failing and since I did a complete recovery wich included reformatting, and reinstallation of XP, drivers and apps it doesn't seem like that drivers are the issue. This system had been running for a couple of years until this.

Try booting into VGA Only mode and see what happens. Report behavior.

That's true, but I'd rather wait and find out what happens when booted into VGA mode before speculating any futher.

I tried booting into VGA mode. In less that a minute the same behavior as described above. I haven't run MemTest86, however, I have run same type of testing software showing memory as functioning properly. The only mode that seems to work is safe mode.

Thanks for all the suggestions. Until now it would stay up in Safe Mode. Before I left last night, I put it in safe mode. This morning, 12 hours later, it shut down in Safe Mode as well, so now Safe Mode doesn't seem to be the exception.

I suspect you do have a bad cap on the motherboard. Could also be in PSU, but your symptoms are consistent with a faulty capacitor in motherboard VRM.

Check caps as nobus recommended. Pay special attention to those around CPU socket. Swelling or leakage is a sure sign that cap is failing or has failed. However, absence of external damage does not mean that cap is good.

You can also try another PSU to ensure that PSU is not the cause.

New power supply was tried (see original posting). I'll check the caps. Now, I may not be as informed about this as I thought but could someone tell me why safe mode allows this sytem to run, at least for several hours, before the partial shut-down... But in any other mode (VGA and normal) this will shut down usually w/i 1 minute? I would think that if it were mobo, caps, etc, it would react the same. Thanks again for all the responses?

I can't give you a definitive reason other than it does sometimes happen (runs longer in safe mode). Possibly due to less stress on system in safe mode.

For a sanity check and to eliminate drivers, boot from a Knoppix CD and see what happens.

I would be more than happy to split points...tell me how to proceed from here....and give you points. The last thing I want to do is get someone upset in this forum.

It's only fair to split points when more than one expert helps. I'm not "upset" per se, just like to be recognized for efforts that lead to a reasonable diagnosis.
