Sorry to rehash an old thread, but my computer stopped working again so I decided to finally finish building my new computer. However, it seems that now the computer starts up, the fan runs, but there is no output of a video signal from the VGA output (which is built into the motherboard.) Then after a few tries, when try starting the computer again, the fan comes on for a few seconds then the fan stops. any ideas on what it might be? i took out the battery to reset the CMOS, but that didn't help. I also read that manual but no luck. any suggestions? i just hope I didn't fry the CPU when i put it in.
