Every program I try to run, after a few minutes I get a Windows error saying the program needs to close. If I close the window the program closes. If I leave it up I can complete a DVD2AVI file however when I attempt to run TMPGEnc or ReMPEG2, which take about 3 hours on my PC, after about 1 1/2 hours my PC reboots. I have a clean install of XP. Athlon XP 2600+ 1 Gb DDR Mem Gobs of disc space.Any ideas? Does XP not like these programs? (I am using the latest versions of all of them).
