    I came home after the weekend to find this on my monitor when I try to turn my computer on, after somebody had been 'cleaning' around my computer area. I want to try and fix it tomorrow and would just like possible causes. Are these it:

    1. Video card is dead/new one.
    2. Video card is loose.
    3. Something is wrong with the ram/may need to take out and put in/get new ram.
    4. Something is wrong with the monitor/cable. Seems unlikely.
    5. Bent connection pins.

    Is that it?

    check all cables and pins / sockets

    or if they have being cleaning check for water damage etc.

    So i poked around and it started working again randomly. I used it again for a few days and then the same thing has happened! When I cam back to my pc the display was frozen so I rebooted to find the 'no signal display' was back? Any ideas?

    Could be a heat problem, any chance the card is backed up with dust? It would explain it locking up.. but not the original problem. What GPU is it? Maybe it's just knackered.

    nVidia GeForce 8800 GTS, had a look and it's quite dusty, don't wanna feck it up cleaning it, will try to clean though.
    Time to wonder what replacement I should get.

    Just blowing down the fan should move some of the dust. It could possibly be caked. 8800s run fairly hot stock right? Cheap bang for your buck would be a 4850. It should run a bit better than the 8800 and pix are selling them for dirt cheap now.

    cheers, might try and get one. Better is good!

    If it's just heat i don't know why it isn't coming on when it is cold, yet after a week it came on fine for a few days?

    I know that's odd alright, the heat would explain the lock up but not much else.. I'm doubt someone cleaning could of damaged a video card either.. Have you tried the card in a different machine? It's a bit of effort but it could save you the €100 you would be spending on a new low-medium end card.

    No other machine to try it on, dang. Might just try and get a good card. Before this happened my computer did seem to over heat once or twice as it would randomly go off after being on for ages.
