I attempted to build my first computer system today and here is what happened:
Powered on the computer and after about 6 seconds of fans spinning, computer shuts down.
Unplugged everything except for CPU (and cooling unit) and RAM. Motherboard beeped 5 times, then it beeped faster, multiple times (like 12 or 13) and then eventually shuts down.
Took the motherboard out of the case and placed it on cardboard. Same thing as above happened.
Removed RAM and the motherboard beeped 3 times (indicating no RAM) and continued to stay on.
Connected video card and monitor and same thing as above happened, but nothing appeared on the screen.
Disconnected video card, and put in one RAM stick. Computer shuts down immediately.
Took out RAM and put other stick in. Computer beeped 5 times, then 12 or 13 times and then shut down.
What do you think the problem is and what would you try next?
