Hi first of all the pc just showed as no signal then after a couple of minutes it said press the ok button within 1 minute too keep it on. I don't know where the ok button is in a pc so it went off.
When I try it now I don't even get a no signal message. We did have a short power cut would it have something to do with that anyone know please ?
It's a zoo storm one and there is power getting to it .
Any suggestions Thanks.

Doesn't sound good. How do you know power is getting to it? Does the computer make any noise as already asked? If not, could be fuse in power lead.If you put your general location in your Profile, somebody here may be able to come and help you.0 -
As already stated, look for any signs of life from the PC: a beep, any lights coming on, a fan even trying to spin etc.
If it appears completely dead, start troubleshooting things from a power point of view:
- look at the keyboard; does it have any LEDs shining, maybe showing the caps lock state or the state of a mode key?
- if you plug a phone or other USB chargeable device into one of the USB ports directly on the desktop, does it appear to be receiving a charge?
- plug some other device into the wall/adapter socket that currently supplies your PC. Does ths device power up OK?
- replace the fuse in the PC power cord - does that help?
If you can establish that power is clearly reaching the box, but the box is 100% dead then I would guess that (at least) the PC's power supply unit (PSU) has gone. That's easily replaceable; the question is were any other components damaged. Only one way to find that out: replace the PSU and see where you're at after that.0 -
Another vote for psu , should be a label on the back showing details of wattage of the unit etc. Fairly generic items so straight swap , undo 4 screws on the back swap output cable connection to various parts.Ex forum ambassador

Had same problem. If pc was running all ok. Switch off and would not turn back on.
Had to use the hairdryer trick to blow though at the fan to get it running.
Eventually found equivalent pcu and fitted it.
Info was on label on pcu inside housing.The world is not ruined by the wickedness of the wicked, but by the weakness of the good. Napoleon0 -
Do you have or can borrow a compatible replacement PSU?
It's also worth trying taking the battery out then try power up from the mains. Worked for me on an old laptop. Good luck.0 -
It's either the PSU or Motherboard

If the PSU is ok try removing other hardware from the motherboard and see if it powers up.0
