My Gateway NV7802u laptop is doing weird things?

Okay, so recently on my Gateway laptop, I have been having crashes at random. Windows 7's error management said it was a problem with the Intel graphics driver, and that it couldn't get the solution. I saw in the windows updates there was an update for my graphic's driver, so I though I should try that and see what happens. I decide to download all the updates. About 30 minutes into downloading the updates, the screen goes black for a few seconds, then says the optimal resolution is something like 33,000 by 10,000. A few minutes later , this happens again, but the resolution gets really small for a few seconds. At the moment I am sitting beside my updating laptop. This is from my IPod. My laptop is used for playing minor games, since the graphics card is old and bad. I would get a pc, but I am still a kid, so I cant afford one. Anyone have any ideas what's going on?
