I'd hate to tell you to buy a new machine without first trying to find out what's wrong with this one. You might want to call around to some local computer repair shops (particularly those who might be authorized Toshiba repair facilities) and see if they would give you an estimate just for a diagnostic check. As an alternative, perhaps a local school has computer repair courses. The instructor might be willing to use your computer for training purposes either for free or at greatly reduced cost. Once you know what needs to be repaired/replaced you could decide if it's worth it or just get a new machine. Which ever way you decide to go, you might be able to get a few bucks for the old machine as a trade-in for parts, etc. Good luck and let us know what you find out.
