Explorer causing problems.

[dataDude]

My main machine is acting very strange. At random time intervals (2-3 hours or not for days) my Windows Explorer will crash. Sometimes it'll crash multiple times in a row after a few seconds or the computer will spontaneously reboot altogether. I'm running WXP, Athlon 3k+ XP, 512 MB. It was reformatted only a couple weeks ago. Because of that, I'm really confused what's going on. I've also been running larger programs that take up the memory, so I don't believe the reboot is caused by bad memory. I'm thinking a possible cooling problem, but does anybody else have any other ideas?

Make sure there are no floating(non used) partitions, they seem to cause errors. I mostly see "exlporer" crashes on windows 98, first case i've heard from xp.

Nope, only one partition going on in this hd. Also, I've been doing some multimedia work (video file conversions) and sometimes they don't convert correctly on that computer. I'm wondering if there's any kind of deep down correlation between those two issues. Years back when I did have 98, Explorer would crash on me like it was trying to punish me for even using it. Now that I have XP, it wasn't until about a month or so ago that Explorer started giving me issues.

have you downloaded all the updates and drivers for xp and your hardware and do you run a firewall ? all so press ctrl alt deleate and list the processes that are runing and do any of them show high cpu use ?
and last have you run a full anti virus scan and a spybot and addaware scans ?
