Random CPU lockup

edited December 2004 in Hardware
The subject says it all. On an older CPU we have (about 3 yrs old)

Soyo AMD Socket A VIA KT266A ATX Mobo
AMD Athlon XP 1700+
GeForce 2 MX 64MB AGP
256 MB DDR RAM
Onboard sound I believe (not sure)
Unsure of the hard drive space, brand, or type

This has been happening the last couple months. We have Insight BB cable (I have an itchy feeling that may be part of the problem) and a ZoneAlarm Firewall and a Linksys 802.11g router (this CPU is hardwired to the router rather than on a wireless connection)

After booting up WinXP (Pro with SP2), the system will just randomly lock up completely...mouse dead, keyboard dead, etc. I have to press RESET to unlock the CPU. Sometimes, it'll do it again, sometimes it won't. Rarely, it'll lockup WHILE WinXP Pro SP2 loads.

What could be possibly causing it? Insight BB provides something called a service activator (not sure what it is...I didn't install it)...could there be some sort of crash happening with that, the router, and the ZoneAlarm firewall? Or maybe I just need to reinstall WinXP? I already did a sweep of viruses (eliminated them) and spyware (with adaware) and it still locks up.

Ideas?

    Not 100% sure, but check all the fans in the case, maybe the CPU fan died? I also had a problem like this before and I found out it was a bad stick of memory. Check the memory with memtest heres the link http://www.memtest86.com/

    Well, I did the memtest and everything turned out fine.

    I have a nagging suspicion that somehow my video card may be having problems...it's been acting up lately, but I don't see how that would cause my PC to freeze.

    I did notice that the PC only freezes when it's cold...when it warms up, everything is fine.
