i have a problem w/ my motherboard. And i have no idea what happenned. My cpu fan doesnt spin on the motherboard anymore and the fan connected to my geforce3 fan doesnt spin. I think my mother board isnt getting enough power...but the green light on the mobo is on. I have a ennemax 300w power supply and have been using this machine for about a year. It was working fine until i opened my case and installed a new cdrom. The only thing i remember taking off the motherboard was the power switch, reset, etc. I need help asap...
