Posting here in the hopes that someone can give me a kick in the right direction, heh.
WinXP Home (updated to last weeks WindowsUpdate downloads)
Geforce 4 4200ti
512mb RAM (2x 256mb)
Updated video/sound drivers (Tested 3 different vid drivers, got latest sound driver from SB)
As of a few days ago, my computer has been freezing irregularily. Sometimes within 20-30 seconds of loading WinXP, sometimes 20-30 minutes. I have to cold-boot it to restart it. However, what's odd is that if I try to boot it up right after it freezes, the case makes all it's usual whirrings and such, but the monitor doesn't receive any information - it stays off. If I wait a minute and reboot it, it boots up fine. Other than a heat wave in the area, nothing unusual has occured. Given the high heat, I'm guessing that I've fried something ;(
Getting tired of it fubar'ing, I did the driver dance, and when that failed, I popped the side wall off, stuck a small fan there, and tried again. No luck. According to my BIOS, it was running at 53 degrees celcius.
After that failed, I pulled out one of my RAM sticks, and tried again. Froze up quickly again. I pulled out the other (so no RAM), and rebooted. It didn't boot, just beeped at me (4 quick beeps in succession), so I turned it off. I've tried putting the RAM back in in various slots (originally was using 1 + 2 of 4), and it doesn't seem to matter what I do - it just keeps beeping at me.
So, I'm stumped. I thought it might be heat, but with the fan blowing directly into the case, it still froze up. The RAM trouble seems very odd. I'd swap memory with this box, but the gaming rig is DDR and this is SD
