I've had my laptop since about March, and it's been working great up until about a week ago. Sometimes when I power it on, a lot of vertical lines will show up on a black background, and then everything will turn blue except this specific area in the middle. Also, my laptop will suddenly lock up at random times and parts of the screen will turn blue. Sometimes, at the lower right of the screen, a balloon will come up saying "Display driver nvlddmkm stopped responding and has successfully recovered." I've updated the video drivers, but haven't uninstalled/reinstalled them since I've had bad luck with that in the past and don't want to be stuck with a paperweight again for any stretch of time. Any and all feedback is greatly appreciated. Thanks!

I would suggest that you back up your personal files and contact Dell. You probably need to have the Laptop serviced. Dell may walk you though some steps.

I had a laptop with a problem that sounds similar. I tracked the problem down to the graphics chip. After a freeze up, the chip would become red hot. The problem was brought on by flexing the case. The graphics were integrated so the laptop was worthless. In any case it sounds like a hardware problem. I would take OtheHill's advice.

Seems to be a fairly commom problem with NVIDIA/Vista. Google the error, Lots of possible solutions. There is nothing to learn from someone who already agrees with you.

Take a look at this page... http://www.laptoprepair101.com/lapt... If one of the screens there matches your problem, the solution will likely be the same. If under warranty, I'd let Dell sort it out. Like OtheHill said, don't send it to Dell with any files you want to keep. Skip
