I own an HP Pavilion computer, windows XP. Computer will not boot up. I replaced the power supply, computer now starts, fans are running, shuts down within 10 seconds. I can start it again with same results. How can I check out hard drive and mother board? Any suggestions appreciated. Thank You, AL Spigarelli

Is the power supply a new one? I ask because it sounds like the power supply is bad. It could be a bad motherboard but a bad motherboard usually makes some type of noise to signify the nature of the problem. A bad harddrive will not cause the computer to shut down unless something is running from it and that something causes a problem. In this case, it should shut down in the same place everytime (for example, in the same place in the startup sequence or when you run a certain program).
Thank you for your suggestions, but the power supply is brand new! It does shut down in the same place every time, but it doesn't even get to boot up. The fans run, and within 5-10 seconds the computer shuts down. Before I replaced the power supply I couldn't start the computer at all. Thanks, AL Spigarelli
It still sounds like a bad power supply to me. Of course, I could be wrong. You might try to find a power supply from another computer and put it in to see if that fixes it. I had a similar experience many years ago. I had put a new power supply in a computer and the computer would run for a half hour and then just shut off. I was perplexed as to what the problem could be and so I took it to a repair shop. The repair shop put a new power supply in it and ran the computer all night. The new power supply had been the problem.
Ray: Tried another new power supply, with same results. Computer turns on, shuts off within seconds. Fans start up, but also shut down and there is no boot up. Any ideas of what to try next. Thanks, adspig
I didn't realize that it was shutting off that quickly. It sounds like something major with the motherboard. Maybe when the power supply went out it allowed more current or the wrong current into the computer and maybe that fried the motherboard and who knows what else. When you start working with things like the motherboard, one wrong move can ruin a lot. It might just be easier to get a new computer. If you have a computer repair shop that knows how to work on computers and does not just send it off to some other location, they may be able to do something with it.
