Hi, I hope this is in the right forum, but I'm calling for help on the behalf of my friend who told me that his laptop is having some weird problem. I told him it sounds to me like his graphics card has gone bad, but I wanted to get a second opinion. Initially, the symptoms he described to me was like he was playing a video game and it would have like messed up colors on the screen and then the computer would freeze up. Then he also told me that when he boots up now, he gets like green bars on the screen, like when you load up your computer and it shows the loading bar at the bottom with the Microsoft windows logo. He also mentioned that when he gets to the login screen he can't really login because he can't see what is going on on the screen. Here's some of what he said to me: "when i start up, the screen will be black and then I'll get green bars that will slowly appear until the screen is mostly green and then it just stays like that the whole time so you can't see anything; and when the problem occurs in the computer when it's normal the screen will suddenly go mosaic color , freeze up, and then shut down." Can anyone confirm my hunch, or have any other thoughts? P.S. - I got some new information before posting this so I thought I'd add it: He also says that he did some searching of his own online and that people with XPS laptops (that's the model laptop he has) seem to have a problem like this and that it has to do with the computer overheating. Which does seem a logical conclusion. So, the GPU overheats, which then causes the GPU to become damage, thus the messed up problems I described above.
