So when I close my screen it'll go into sleep mode. Then when I open it up, it will have my cursor all messed up. I can't really explain it but it's like data matrix barcode or something. Then my computers really slow, when scrolling up and down a webpage it'll lag and whatnot. I'd restart the computer and everything would be working fine. It doesn't usually occur but it happens occasionally. Could it be a defective video card/mobo?
 
i would bring into an apple genius bar for further tests. it doesn't sound good tbh...
 
Happens to me once in a while on my white unibody MacBook, too. I doubt it's a videocard issue, must be software or driver.

Usually it clears out after I login, so no biggie.
