My old pc has just died. When I go to switch on, the pc powers up then switches itself off after a few seconds. The led comes on and the fan whirrs in to action but thats it, no boot up. Afterwards it just wont come on at all.
Have tried different power leads and sockets, to no avail. Haven't opened it up yet, any suggestions?
If the computer is switching off after a few seconds - and presumably before any POST beep, then your problem isn't in Windows because your computer hasn't got that far. Bowie is probably right and the power supply has failed. Fortunately PSUs aren't too expensive and are very simple to replace. Before you go out and buy a PSU, though, eliminate a few other possibilities. One possibility is a corrupted CMOS, so try resetting that either by the reset link or by removing the battery for about 10 minutes. Next try unplugging the drives from the motherboard. If that doesn't help, then unplug everything else from the motherboard except the processor with heatsink, power supply, power switch and case speaker. If that doesn't help, unscrew the motherboard from the case and place it on an insulating surface such as a sheet of card. After that it can only be one of the few remaining components that is causing the problem.
There was an article in a recent PC Pro where someone "Jump Started" a PC using the power from another. Disconnected from running Mobo and connected to non running. Need a long enough lead of course but saves dimantling.
