I have a very peculiar problem that happens irregular and has something to do with my powersupply...My computer suddenly just shuts down as somebody pulled the plug...If I try to restart it just starts the fans and shuts down immidately...If I wait for a while, if Im lucky, it re-boots the computer as it should but shuts it down again after a while...If I replace the power supply unit it works again it works for a few months...The only thing I can figure is that it has to do with my monitor that is like 5 years old all the other stuff is almost brand new or been in a previous computer without causing any similar problems...it is not a heat problem I have seen to that thoroughly...

The X-file thing is that I plugged in a previously, which I thought was a faulty power supply, and it started my computer right up without any hassle...

Can it be dust or cat hair that causes the power supply to "overheat" or just mal-function...I have two persian cats...however I do have an PII 350 Mhz just beside my problem computer and it works fine...

Could it be a static discharge problem?

Any ideas that can point me in the right direction is much appreciated...

System...Epox EP-8k7a+ one HD 20 Gb...512 Mb DDR RAM...Hercules Kyro II video card...Soundblaster Live...Two network cards...Cd rewriter...cd-rom...I rarely have any other problems like crashes or shut downs...re-boots...in other words a reasonably stable system when the power supply works...
