Video Card Dying?

[JasonLee]

My laptop video card used to be fine a few months ago, but in July, it started acting weird.

I used to play games on this laptop and it was running fine. I will have to say that the most hardcore game I ran on this laptop would be Call of Duty 4, but other than that, it was just those free mmorpg like maple story and flyff. After I reformat to try windows 7, vista, back to windows xp and then back to windows 7, my card started lagging badly. When I'm in game, it would be fine for about a minute (nice fps), then it starts to lag. And when I ctrl+alt+del, it takes a bit of time before it pops up. Sometimes, I have to just power off my laptop.

About 2 weeks ago, I reformatted and installed windows xp pro sp3 to see if it was just the OS and drivers, but the problem still remains. Also, I can't watch flash video on youtube as it starts to lag, but I'm able to watch .avi and such video with media player classic without any problems.

You'll need to get the laptop opened up and remove the accumulated dust on the radiator fins that is causing a lack of air flow to cool your system components (CPU and GPU). The long you wait on this the more damage it will do to your video card.

After the video card is run at high temps too long, the internal components will start to fail. ***anytime*** you feel like your laptop is overheating you need to stop what you're doing and shut the thing off. Overheating is a serious problem - not only can it harm *you* but it can easily make your laptop nothing more than a paperweight.
