I have a shut down issue on my pc, KV7 mobo and AMD 3000+ cpu. I have extensively troubleshot the hardware and software replacing or unplugging every item except the cpu and mobo. I also booted up with no HD and only the windows boot disk and it still shuts down. The odd thing about this is when it shuts off i can not power it back up until i unplug the power supply and plug it back in. Thinking it was the power supply i tested that by allowing the system to sit in bios window for hours. Running the computer in the bios setup is the only way it will not reboot. So correct me if im wrong but that kinda rules out power supply mobo and cpu ? Let me know what you guys think. I have also tested heat and cpu is running at 52 degrees c. Thank you for any advice.
