hello, i recently built a computer for someone I know, and it was working flawlessly, installed windows, drivers, etc. No problems at all! Then, my girlfriend wanted me to set up her computer where the other computer was plugged in, and when I moved the computer to the other side of the room and plugged it in, all of a sudden, it doesn't work at all! Nothing I've tried helps - resetting the battery, switching the ram, video cards, removing all pci cards, ide/floppy drives, etc.. It shows nothing on the monitor, and just beeps at me. I've never heard a computer beep like this before, and I know about debugging problems based on how many beeps, how long, etc, as I am A+ certified. The computer beeps in two alternating tones, high and low, and sounds like some sort of siren is going off. WTF?! Any help would be greatly appreciated! The person is starting to get ****ed off and I can't figure it out.
