Hello, I keep my computer on/running and plugged into a battery backup surge protector. Yesterday evening, the power in most of our area went out. Eventually when it came back on, I tried to boot up my computer. It powers on each time I press the power button, but then shuts off in 2-3 seconds. I am not sure if something spiked or damaged in my computer. Does this sound like a power supply issue to anyone? -AMD Athlon XP 3000+ CPU - sometimes clocked up a few ghz -nVIDIA nForce2 ASUS A7N8X-E Delux ULTRA 400 -2 Gigs Corsair XMS DDR400 PC3200 RAM -ATI Radeon x1600 AGP 512RAM runs F.E.A.R like war

Have you tried it without the surge protector?

"Yesterday evening, the power in most of our area went out. Eventually when it came back on, I tried to boot up my computer" so your PC is plugged into a battery backup. What happened when the power went out? Did the PC stay powered up, or did it crash? If it stayed on, did you shut it down properly, or did it stay on until it eventually drained the battery, and then crash? who's the manufacturer of your battery backup/surge protector? How old is it? Because your issue does sound power related. Unfortunately, if the surge protector is no longer performing as intended, dirty power could cause damage to any component in the PC. Damage to the PSU, RAM, MoBo, and/or CPU could all cause the symptoms you're seeing.

My battery is one of these: http://www.arcocomputers.com/images... by APC I wasn't home when the power went out, so I am not sure what happened. I'll try it in the wall outlet when I return home from work. And remove all parts (except the MB) to see what happens. -AMD 2.1ghz Dual Core - 4G Corsair XMS DDR RAM - Windows XP SP2 - 500Watt PSU - GeForce 9800GT

well,not much will happen if you remove EVERYTHING except the mobo, but you can strip it down quite a bit: remove all drives (hard, optical, and floppy) remove all PCI cards (network, sound, etc) remove all but one stick of RAM you should leave only the mobo, psu, cpu, ram, and video. without any HDDs, you won't be able to boot into Windows, but you should be able to get into the Bios. if the PC is still rebooting like before with this configuration, you can try a different stick of ram. if you're still getting the same behavior, you've isolated the problem down to PSU, mobo, or CPU.
