My wife's PC has been giving random problems, such as refusing to boot into Windows (Win7 64bit), but a bit of unplugging memory and SATA cables and replugging them has usually sorted out the problem.
But now, when switching on, the PS starts up, the CPU fan starts up and then shuts down and starts up continuously. The keyboard lights flash on and off with each cycle, but that is the limit of what happens.
What can I look for, as I have tried the unplug, plug routine, with no joy.
Thanks for any help.
