Pc cuts off and won't boot.

[Jonny ///M]

I had the pleasure of receiving an insurance replacement pc after my cat decided to kill my old one but a few weeks ago she tried to kill this one by peeing on it!

Spec is:

Asus crosshair 3
Amd X2 250
8gb Kingston pc3-10700
OCZ Stealthstream 700w
Ati 4850

Thankfully she didn't and I managed to get it going again somehow but randomly I'm getting some issues and I want to track down what's causing it so I can replace it.

A while ago it cut off randomly after I took out a dodgy HDD and reinstalled windows on another drive. I got a new 2032 battery,popped it in and it powered up first time. It then worked for a week or two and then cut off again, so I popped in another battery and got nothing this time.

Tried leaving it unplugged overnight and still nothing the next day, left it plugged in but with the switch off on the psu for a day and when I came home it powered up!

It cuts off randomly, heavy load or not and the fans etc keep spinning just gives a black screen with no response.

Anyone have a good shout at what I should replace, I'm leaning towards the motherboard for now.

Ok now it has done it again after putting it into sleep mode! I know people have problems with sleep but mine won't even spin the fans now :S

Jumped the psu and that seems to work ok, the video card has both red lights on now thought.

I'm thinking a short somewhere = no response from the power button?

I would try another PSU, if you can get your hands on one. If it’s not that then next most likely would be the motherboard.
