Hi everyone; I have a dell D630 that I started having problems with about 2 months ago, in the middle of normal functions vertical rows of small green bricks would appear, followed shortly by a crash. Then, I can power it back up but the screen will remain black. It lights up, the pixels are obviously functioning but it is black. Every once in a while it will work again but only for about 1-5 min and the green lines will come back.

This happened shortly after I had it outside during a construction project where it may have gotten some dust in it or something... I am guessing this is relevant?

I have tried blowing everything with a little keyboard cleaner air can, but that is all.

Any help would be great.

Thanks,
Ben

Hi bbblades222,
is that onboard video, or a card? the green lines,bricks, etc sound like an overheating problem, most likely vram. also you indicated that you had to recently move your machine, try re-seating your graphic card (if you have one) . and welcome to Techspot
