Problem with L4SMG/651+. A lightning strike. A friend bought a computer on TV. When it arrived, they plugged it into a utility power strip and a phone jack. A lightning strike destroyed the TV and VCR. The computer stopped working as well. The motherboard is the L4SMG/651+. 120GB hard drive. 512MB PC2700 DDRRAM. When it came to me, it did nothing except the power supply fan and the CPU fan spun. I pilled the modem and tried again. This time I got a long beep. There is no video, which is built in, as is the sound. When I push the case's power button, it powers up ok, but does not power down. I must turn off the power supply switch. Anyone have any ideas? I would really appreciate some help. Carl
