I have a problem with my TI-83. Every once in a while, when I turn the calc on, it just resets. I dropped it once a while ago, and I think that might be the reason this is happing. I have an even worse problem with an 85, if I bump it, even lightly, then the calc resets, or if it gets shaked a little the same thing happens. Can somebody help with this? Michael Riso riso@jps.net
