Computer gets power, shuts off, gets power, repeats, never boots
When I got home from work tonight, my Win7 desktop appeared to be asleep, which is normal. I hit the power button to wake, it, walked away, and when I came back, it was not up as I'd have expected.
I looked more closely and something really weird was happening.
The fan would turn on and the power lights would come on. Not sure if I heard the HD (there's an OS C drive, and mirrored data D drives). Three seconds later, it would power off, without anything ever displaying on the monitor, no bios screen, nothing. This would just keep repeating.
I managed to get the CD drive open and put a boot disk in, but the whole sequence happens so fast that it doesn't even recognize the CD or try to boot from it.
Right now I have the computer turned off and unplugged, and hope that this will rectify itself with the passage of time.
