Okay my computer did this before and eventually the lcd went black and wouldn’t work at all. Unfortunately it’s happening again.
What happens is that I will be in the middle of doing anything, and my computer will kind of crash into this. (please view picture)

and the little square is in different places different times and theres not always lines.

Well I still have a warrenty for this labtop and I was wondering if this was a good enough excuse to return it and get a new one. Cause I didnt do anything to the labtop to make it do this and ever since I got it, it has been a piece of crap and doing this stuff.

And is anyone else familiar with this?
Any thoughts/opinions/suggestions appreciated
