PC mysteriously dying overnight

I left my ageing desktop PC seeding a torrent overnight and checked on it this morning to find that the monitor would only show a 'no signal' message.

I tried moving the mouse, tapping a few random keys and ctrl-alt-del to no effect. I reset the machine using the button on the front of the box and eventually ended up manually shutting it down.

Now when I try to turn it on nothing happens - not even the initial beep from the internal speaker.

I'm guessing that this is not a particularly good sign but I'm mystified as to what might have happened. And is there any simple way of bringing it back to life?

At the very least, might I be able to remove the hard drives and get a laptop to rescue my data using a drive enclosure?

Any advice or sympathy would be much appreciated.

Sounds like that most irritating problem, "the undiagnosed hardware fault". Will probably take some hands on fiddling with to diagnose. Usual method is to strip the PC down to basics, ie one stick of RAM and no peripherals, where hopefully it will work, then one by one put things back until you find the problem component and replace it.
Does the desktop have a graphics card, or does it use on-board MOBO graphics ?
As to rescuing data, this depends on what's gone pear shaped. If the hard drive is OK then the data is safe, if it's died then you have a problem.

Thanks for that.

Sounds like a job for the weekend...

Irritatingly, I was in the process of gradually extracting everything I wanted to keep from that PC's hard drives and getting rid of it. It hadn't even been switched on for a fortnight.

No signs of life at all could be PSU, motherboard or CPU.

happened is that if there's lighting the mother board could of been fried up.

i am aware that most computers left plugged in on or off or standby during a thunder storm where there is lightning can affect the circuits of the computer. I always unplug from the socket my computer or use the on off switch if there is one.

Im making an initial guess of what could of happened.

Could be the motherboard battery as you state it's an older system.
