My dh the pc guy says it's your video card or its driver - it's having to work too hard to keep up and is causing your overheating problem. He said it's a very common problem. He went on to say a bunch of stuff about standard resolutions and 3-D thingamagummies but my brain rolled over and I didn't catch it all.
OK, he's typing now...
Hey,
It's more than likely your video card is the problem, at standard resolutions running day to day applications like your internet browser or Word/Excel the card isn't required to do much processing at all. When you engage a game or application that requires the card to work much harder to process the greater amount of data necessary to render 3D images, particle effects and the like it creates more stress on the card and correspondingly more heat. Most video cards are designed with heatsinks or fans to dissipate the increased heat under load but if your card is faulty or improperly cooled you will see all kinds of malfunctions from your computer freezing or running slow to video artifacts and glitches on the screen. From what you describe I'm almost certain your video hardware is faulty or possibly your software driver that interprets commands to your card is corrupted, replacing the driver is just a matter of finding out the model of card you have (most likely ATI or Nvidia) and downloading the correct driver from the hardware website. I can give you exact details on how to do that if you like but I think it is just as likely that your hardware is the problem, I wouldn't let the store you purchased from give you the run around on that.
If nothing else, you should be able to bring it in and make them look at the problem with the DVD player. With any luck solving the one problem will solve the other, and it should be easier to convince them the DVD playback is faulty.
And if it has a general overheating problem they should fix the overheating problem. It should work even if it is not on a chillmat.
