On computer last night and I pushed it back against the wall.
As I did it heard a clicking sound. Pulled it out and it stopped. Pushed it back in and it started again.
I then realised that a plastic tie wrap was going into the back and touching the fan (i think)
I moved a few bit about and then suddenly the screen all went blue. You could still see what was on the monitor but it all went a blue colour!!
Turned PC off......now nothing happens...all blank!!
PC fires up but nothing happens and monotor stay blank even though its switched on!
Any advise/help appreciated
