I've been having issues with my laptop that gradually got worse, making everything run super slow or not working at all. Firefox kept on crashing and eventually stopped working altogether. I've been getting persistent script errors and computer shutting down every 10 minutes or so. Took it to the nearest Geek Squad and I was told everything was fine except for the fan, which is causing the laptop to overheat and shut down automatically in order to cool down. So they sold me a cooling pad and promised that it would solve everything.
I do take care of all the regular maintenance that is required to keep the computer running properly...defrag, deleting Internet files, virus scan, Windows updates, etc...so what could be the problem?
Finally after uninstalling 21 programs that I never or rarely use and uninstalling/reinstalling/updating the ones that I do use and still getting nothing resolved, I looked at my computer problem reports [Control Panel>Performance Information and Tools>Problem Reports and Solutions] and discovered THE antidote to all the issues I was having: Windows Live OneCare safety scanner for Windows Vista and Windows 7
After countless hours of running the full service scan, I got a report stating that there were about 1500 unnecessary/orphaned/misplaced files clogging up the registry, causing the computer to run slow and programs not running properly, so they had to be deleted to fix the problems.
YES!!! Done done done!
Now it's running like a lean mean super fast machine again!
I would highly recommend it even if you're not having computer issues as serious as I was having.
