I have just installed a Nforce 2 A&N8XE Deluxe motherboard. I was in the system bios at the time when the computer screen unexpetedly went black. I tested if it was the monitor's fault but the monitor was fine. I noticed in the computer that the video card was pretty hot and when i turned on the system there was no beep and the cpu fan wasn't running as well the screen was still black. I was womdering if anybody knew the problem and could give me the solution. Nevermind i found out my video card overheated.
