So I figured I'll help him out by pulling the x1300 and replacing it with a evga 8600gt. While I was at it, I'd also pull the 4200 and replacing it with a 5200+. This is where my problem started.
Everytime I try to install my OS, Window XP Pro, it'll make it all the way to the system file copy, then at any given random time during the copy, the computer reboots. I tried about 5 different copies and it all yields the same result. It'll either stops at any given point, or it'll just reboot. Any advice given will be appreciated.
Did you replace both the CPU and video card at the same time or did you run the system for awhile after replacing the video card but before installing the new cpu?
Do you mean you have the problem while booting your OS or did you actually reinstall it? If the latter, why were you reinstalling your OS in the first place?
Did you do a complete reformating of the HD first, or just a quick reformat?
Yea, the 4-pin is plugged in. I replaced both component at once since I figured it was more convenient that way (have to take desk apart just to get to the computer). After formatting the drive, the disc will copy files onto HD, thats when the computer would reboot. Im only installing a new OS because I didn't want my brother's friend to get to my personal infos since he always have friends over and they uses the computer alot. I have a brand new Corsair vx550w laying around, probably give that a try. Thanks for all the advices so far.
