Thread: Booting Issues

ok my desktop computer is having issues.

the problem started happeneing after 30 mins or so of heavy activity, the computer would lock up. totally freeze, not blue screen style. Sounds would get stuck and everything. I reinstalled windows xp and the problem still continued. Soon the ocmputer would osmetimes finish booting up to windows, and sometimes not. After booting in windows it would lock up the second I started loading up anyhting. Then a few months ago it wouldnt even finish booting Bios (everyhting would power up, and ten die withing 4secs). I got frusterated and stoppe dmessing with it until now.

I tweaked the power supply a little, and now it will stay running for awhile, but now nothing is displayed on the monitor (monitor stays in stand by mode). All fans turn on and HDD Spins

-tested monitor with laptop, and it works fine
-swapped gfx card with 3 agp cards, and tried 4 different pci cards
-checked all connections
-moved memory around in different slots
-tried booting from 2 different hard drives

and none of this has fixed this problem. Does any one have any ideas as to what this would be? I was thinking either CPU or MB. Is there any way I can rule one or the other out?

a few thigns abotu the system
-nvidia gfx card only has about 1 month worth of use
-power supply only about 6 months
-hdd is abotu 1-2 years and the other is about 4 years old
-Asus MB (5 years old)
-AMD XP CPU (5 years old)
-optical drives and floppy are disconnected (have tried with them connected same issues)


any input is appriciated.
