help with 'exception_access_violation' error

Doesn't give a code. Just says Windows Exception in top border and EXCEPTION_ACCESS_VIOLATION. I'm trying to play a lousy 100mb game and getting this error when I try to open it. This is the only time this has happened. Most games I play are 1gb or less. Been going round and round on the googles looking for a fix and can't find anything. At least anything I'm actually capable of doing...

What I've found are references to both Java and file errors in the system. I just don't have a clue. Have latest Java and all other updates. Run Malwarebytes, use MSE. Running Win7 home premium, 8gb RAM. let me know if you need other info.

And, if I may also ask - is there any software that checks your entire computer for bad/missing files/dlls.I MAY have a bad sector in my HD but was told since it's 1TB, another sector would take over for the bad one? I have to sleep now. Blathering...

Any help is greatly appreciated. I really hate losing to a computer...
