Hey all, hope someone can help me here. For some reason my computer keeps powering off, I mean totally just shuting down and you cannot restart unless you turn the main power switch off in the back and wait for like 30sec to a minute. I noticed that the CPU usage goes to 100% when I am running certain programs and then once it does this for a minute or two it shutsdown. The following are the things I am doing with my computer when this happens: 1. When I use DVD shrink to compress a DVD movie to fit on a DVD-R. I have an older program that works fine, but for some reason DVD shrink always makes CPU usage got to 100%. 2. I have a program Ulead movie creator (something like that). When I use this program to convert mpegs to burn onto DVD, during the conversion process the CPU usage goes to 100% 3. Sometimes, not all the time, when I am playing pretty high graphic games, computer just crashes. In all these cases the CPU usage goes to 100% for one program and then the computer just shutsdown, no errors. PLEASE HELP!!!! Computer Specs: AMD 2700, 2.0Mhz, 80Gig HD, 1064 RAM - computer was built from scratch by a wholesaler, work fine for a a while (6-8 months) suddenly started doing this.
