*sighs* Only you, TJR, would manage to post a non-FPSC related question on a FPSC-related board and then have the idiocy to inform us that you hit your computer as a solution to what could have been a software problem. Avid's right--if even the slightest thing gets knocked loose on the motherboard, there goes your entire computer.
I'm telling you this for your own good--take your comp to a professional and have them look at it. A hundred bucks or so to fix a simple motherboard issue is going to be a better option than paying $500 for a Walmart-brand PC that may not even have half of what your current comp's got now because you were enough of an airhead to abuse your comp further.
