Was playing saints row earlier turned it off went downstairs and left my computer running came back after 5 mins and there was no signal going to the monitor which I thought was fine as windows usually turns the monitor off tried to wake the pc up by both tapping the keyboard and moving the mouse to no avail computer wouldn't wake up so I tried a hard reset the computer wouldn't turn off so I just Flicked the switch at the back of the psu and now whenever I turn it on the same thing occurs I removed everything connected all of my ram except one stick and still nothing
Any help would be appreciated
