For the past couple weeks my machine(XP, Gigabyte GA-7VAX, Athalon 1.6 GHZ, pc3200) was randomly rebooting and occasionally blue screening.
First, I wanted to rule out software/driver issues (and I had been wanting to do a re-install anyways) so I tried to reinstall XP. Part way through my install I got a blue screen... so I could forget booting up again. I removed a bunch of hardware leaving only my graphics card(Gforce ti 4200), one HD, floppy, and CDROM drive. After a few more blue screened(usually different errors) attempts at a reinstall I checked the power supply and the fan was dead.
Went and bought an Antec 430W. Plugged it in and the install started working!... and then blue screened half way through. Tried the install/setup a few more times, each getting successively farther along in the process... only to bluescreen. So I tried swapping out between 3 available sticks of RAM. Mixed results all ending in failure.
Ocassionally when pushing the "power up" button the fans would hum for a few seconds and then everything would shut down.
I'm guessing a bad mobo. Any advice?
