I have an old machine that has run like a champ for years, but something is causing it to freeze up and reboot lately (infrequent BSoDs too).
Pentium III-450
Intel 440BX chipset
384 MB RAM
GeForce 3Ti200 video card
I replaced the power supply but that didn't help. I ran MemTest86 against the memory a couple times with no errors. I reformatted the hard drive and re-installed WinXP and all the service packs/updates. I installed the latest video drivers.
The odd thing is that the reinstall completed just fine. But after sitting overnight, I'd find the machine frozen. I figured that was OK and put the case back on and now the machine freezes within minutes of boot up.
I suspect some kind of overheating problem somewhere since the problem is worse with the case on. But how do I narrow down where the problem is? The fans are all working fine as far as I can tell and the BIOS says the CPU temperature is around 40C.
I have another AGP video card I can throw in to eliminate that as the problem, but if the problem is still evident, is there something I can use to test the CPU and motherboard? Am I missing anything else that might be to blame?
