Very unusual problem, my WindowsME crashed and my HD was not being recognized at all, so I installed the WindowsXP Profession Evaluation Copy(build 2600) and it was working great. I made 4 partitions, 3 3 GB ones for OSs(still only have XP at the moment) and one 25 GB one for applications/games. It worked fine 2 days ago, but yesterday it started randomly shutting down completely and powering off. I have no clue what the problem is, I thought it was heat but the timing is too consistant, and as I type this it has stayed on for 20 or 30 minutes, unusual. It was almost to the pattern where it would stay on for however long I left it off up to 30-45 minutes max before it shut back down. If anyone else has had this problem and knows how to fix it, please reply. Thanks.
