My comp has started to have a bad habit. It can crash on me, any time, anywhere. Notepad has just crashed

on me in the most unexpected moment. I am planning a complete re-install soon, but first, I would like to know something:
Is it possible to avoid my computer starting with Scandisk? If it crashes and I abandon scandisk, it will still demand that I run through all the files at the next reboot. It's not a serious problem, I can simply press ESC and quit scandisk, but standing in front of the computer just to do that is tiring. So, is there a way to stop scandisk from running at reboots?
