I had built a PC using an old alienware case essentially gutted and replaced the motherboard and processor. New RAM. New fans, new DVD.Hard drives were still good and bootable. The PC has been working for 7 months now. I went to work with the it powered up, I was running a defrag and didnt want to wait on it. When I hot home my wife informed me there were two power hits where both our computers went on and off a few times. hers (its an old dell) booted right back up. They are on ups but old ups and honestly I have not checked the batteries for a while. Now my computer will not power on. I get nothing, no beeps no fan nothing. I have tried 2 different power supplies, niether worked. I have replaced the motherboard. With a combination of the new mb and new ps still no power. I have tried disconnecting the front panel indicators and jumping them with a screwdriver. nothing.. I have replaced the video card. Is it possible its the ram or cpu? Those are the only parts that are not changed out,
