I have a Sony VAIO PCG-GRZ610. It's got a 2 GHZ processor and 512 MB RAM (Well, it comes stock with 256, but I added another, but under System it's only showing 256 now... not good). Anyway, it used to run quite well, but now, after a little over 2 years, it's running awefully. It takes 10 or so seconds to open up the start menu, and it shuts off after about 20 minutes, then if you turn it on, it shuts off after about 5 minutes. I know it's overheating. The bottom is so hot that it almost burns to the touch. Is there any way to cool it down? Is there a way to salvage this computer? It is running like it has absolutely minimal processor speed, and I need a little more power out of it. Any help would be wonderful.
