Everything worked fine for almost a whole year, then my tablet started acting strange last night. It got really bad this morning so i was trying to install a antivirus thinking that might help, but it wouldn't open. Reports of program failures were popping up like crazy, so i turned it off and back on about five minutes later. Now its been over an hour and its stuck in the cyanodenmod loading screen, its never taken this long.

Is there any program i can use on my laptop to wipe everything on my tablet and install another os? I'm not sure how it'd work seeing as how its stuck loading. Do i need to let the battery die? I really just want to plug it in and wipe the whole thing but i haven't a clue where to start.

Please help? :(
