The PC does not start up first thing in the morning or whenever it has rested for at least 3 hours or so. When I press the power button, nothing happens, no sounds, no lights. If I keep trying, especially when I hold the power button in, it comes on but then: Gives: windows protection error. Please restart. or windows protection error while initializing configmg or after restarting it would hang displaying the Win98 logo screen after several attempts and going through to safe mode, it will give different fatal exceptions at different offsets. I have tried the following. Replaced power supply. Replaced RAM. Done regscan /fix. Ran scandisk. This system is a AMD 1000 MHz with 128 PC133 ram and a 16MB Voodoo AGP video card. I have tried all advice on your forums, nothing is helping. Please help. Any advice welcome.
