Hi All,
I'll try to explain the background to this issue as concisely as possible
Mother-in-law's computer had a virus, so we gave her one of ours that was not being used while I fixed hers. While she had it she tried to update Live Messenger, but it froze doing so. Rather than switching it off by holding in the "Soft-off/on" button on the front of the PC, she switched it off using the switch at the back of the Power Supply Unit! When she tried switching it back on it may or may not have made a pop noise, and of course it now does not power on, no sign of life at all.
My initial thought was she killed the PSU. I unplugged all leads from the suspected dead PSU and connected in a spare known-to-be-working power supply ~~ I had only used this spare the previous day to diagnose a friend's dead PSU in their PC, which worked so we went out and bought a new one and fitted it to their PC, all happy, but I digress...
Once I had the spare connected, I plugged it in to mains power and turned on the power to the PSU all looking good - the blue light and the fan in the PSU are going as well as the fan in the case. I press the power button to turn on the PC, immediately there is not so quiet BANG, a spark and a burning smell coming from the spare PSU. I immediately remove the mains plug and switch of the PSU. I disconnected the PSU from the PC and tried plugging in to mains and switching it on - completely dead now
It would appear something in the PC has fried the PSU, I'm afraid to connect another PSU, lest I fry that one too.
What further troubleshooting steps should I take to work out what is causing this, or am I better off junking the whole thing to be on the safe side? It was a PC I built back in 2005, so not exactly worth much by today's standards, but still I can't exactly afford to go out and buy a new one to replace it at the moment.
Cheers
