you could try to install new drivers for the graphix card...
since you can c logg in screen the card shouldnt have broke... but it might since those stripes are there. my graphix card has crashed once... and then there was alot of those stripes.....
alltough the screen might have crashed...
but atleast try the drivers... that is the only thing I can say... otherwise I dunno....
It can, if your card has crappy cooling
Also, that still means worms 2 fried your monitor.
