My girlfriend has a Gateway 500GR with only an added 128 graphics card. One day everything was working as it should and the next day when she went to turn it on, the power came on, but that's it. Fans were blowing and the mobo light was on, but the hard drive didn't spin (at least I dont think it did) and the monitor receives no signal no matter which card it's plugged into. I don't recal hearing a beep when the power is turned on, but I could be mistaken. Obviously you have to hold in the power button to shut it off. ANY IDEAS ON WHAT THE PROBLEM OR SOLUTION COULD BE? Any help would be greatly appreciated.
