The fact it needed vacuuming to get all the crud out means that the video card could have been running hot and now it looks to have failed.
Hi guys, a few days ago my HP desktop computer started turning itself off while I was in the middle of using it. Now this morning when I turn on the computer the blue HP start up screen goes fuzzy and then the screen goes crazy and shows all different colours (links to pictures below). I have taken my computer apart and vacuumed the dust and put it back together. I have not installed anything in the last few weeks so I don't think it's a software problem. I have tried it with another screen and it does the same thing so it is not the screen.

If anyone has experienced this or can give me advice on what to try, I would appreciate it greatly.
