You may have a heat issue in your laptop. I would contact acer about warranty if you have any left. Have you backed up your windows files yet on a dvd? You'll want to do that in the event your hardrive is failing. Regarding heat, only thing you can do is get a laptop cooler with fans; some are only $15 or less on sale. Other option is to reinstall the cpu heatsink with fresh thermal grease. It all depends on your level of experience and warranty situation. If acer will take it back, then let them fix it.
