Hi,

On startup my niether my mouse/keyboard/monitor fail to respond in the slightest. There's defineatly power going to the mobo, all the wires etc. are seated correctly. It happened the other day then randomly started working again a few hours later. Then, yesterday, my PC crashed and when I rebooted this happened.

I'm running windows 7 64 at the moment and am at a complete loss and would really appreciate any help I can get.

Many thanks,
Henry :)

do you get any beep sounds from your system? how do you know the keyboard and mouse are not working if there is no display? do they light up?

if it was me i'd take the system apart so it's just a mobo, cpu, on board gpu, psu and ram then try booting it up then if it works add one device at a time till i find what's causing it.

might just be the graphics card, could try using the onboard.

i wouldn't recommend doing this if you don't have hardware experience though.

Yeah, I was thinking of doing that, but I wanted to see if there were any fixes before I started breaking it down. There aren't any beeps and I can tell that the mouse isn't on as both it and the keyboard light up. I just don't understand why it started working again only to stop randomly. It's really baffleing me to be honest.

so the keyboard and mouse do light up?

if that is true then it's looking more like a graphics problem, i'd disconnect the graphics card and use the on board first of all.

also do you have a 2nd monitor to try?

They do normally light up but not now.

I know it's not the moniter, mouse or keyboard as I've plugged them all into my laptop and they work a treat. Just not with my desktop.

I've tried everything I can think off. I'll just have to break it down and build it up when I get time :(.
