Hello, I recently built my current PC, which is a 3.2ghz pentium 4, gigabyte GA-8IG100-G motherboard with 2gb of geil value ram (2.5, 3,3, 6) with an AGP x800 XT PE video card. Sometimes the computer will seemingly power down, monitor displays the 'no sigal' message, but the CPU and case fans continue spinning. Normally a simple reset will allow the computer to post, but once I had to reset the bios. I am using a Antec 450watt PSU, which the shop I got it from assured me was the best they have as it cost a fortune. This might be wrong Had a few problems with this PC, and am starting to get worried its going to die again. Any help would be greatly appreciated. edit: Max cpu temp is 35 degrees after pc has been on for a while, system isnt overclocked, all cpu, DIMM and AGP voltages are at default.
