So, my grandma was being very generous and decided to buy me a new laptop. I had told her to get me at least a pentium, and at most a dual core (after that I wasn't very picky [besides hd and memory]). Well AFTER she had already paid for the laptop I get to find out that it is a Celeron R 900 @ 2.20 GHz, 2.19 GHz Toshiba with 2 gigs of ram. What can I do to make this darned computer better/faster/not freeze up when I play simple games? I've thought of getting an external hard drive and more memory, but I don't know if either of those will make a real difference in the performance. Any help?
