I am very well experienced on computers and rarely have a problem I can;t fix, but I have one now.

At times, my laptop would freeze and the scree would o funny, usually with lines going across it or the screen would go mostly white with a big black bar in the center of it (Vertical bar). I have to shake it and smack it to get it back to normal. It's been only doing this for the past few months.

I noticed especially if it's in certain position, like an angle, it does t more. Almost every time I turn it on, the screen is white with the big black vertical bar on the center. But I pick up the laptop or give it a gentle shake it goes away.

I have taken the laptop apart and couldn't find anthing wrong with it. I've never had this problem with computer before. I'm starting to think a faulty video card.

This laptop isn't that old, I ha bought it in February, 2007. it's an Acer Aspire 3680.
