I have a problem with my computer. It just won't turn on! Its an eMachines desktop with a Celeron D at 2.93 GHZ, 512 MB of RAM, and a 80 GB hard drive at 7200 rpm. It can't be more that 13 months old, and I think the model number is something like T4010. Yesterday evening I went to turn it on only to find that it was totally unresponsive. Nothing happens, *at all*, when the power button is pressed. No sounds, no lights, no internal activity. The computer and all accessories are plugged in. No wires/cables are damaged. The only thing I can think of - and quite an obvious cause of damage - was the giant lightening storm we had here. But the computer was plugged into a UPS battery back up and surge protector, a very expensive one (Sigh). It was working and fully charged during the period I was away form the desk. Further, the power to the house never went out and the lights never even flickered. I tried another PC (which was also on and running during the storm) with this PC's cables and the UPS, it works. It is completely protected by Norton antivirus, and supplemental AOL protection. (Not conflicting.) I opened the case and didn't observe and physical damage. The power button is mechanically functional. (A small green light is visible on the motherboard when plugged in, but everything else looks totally dead.) Any ideas what this might be? Thanks.
