Aright, you have 2 options here.
A: Either download system mechanic standard trial and have it do afull scan of your computer.
If it fins any system problems which I'm sure it will let it fix what it can, next use defraggler and ccleaner and let it clean out any temporary clutter and gargabe laying around.
B: if that does not work at all, and you keep getting the same error and more problems I recommend you try some new ram for now and do a clean install if your os.
If you have any success without your laptop going mission impossible on you, feel free to leave me 2 packs 24 cans of diet mountain dew.
