Boot Driver Error

Hi guys, this is really weird. My tower is brand new, I’ve had it for only 4 months, and it works great…but lately, I’ll have the computer running, and everything’s working fine…then all of a sudden, this blue screen pops up that says “corrupt driver….explains a little..then “if this is the 2nd time you’ve seen this screen contact technical support”. When i look at the “system tools”, the boot driver says “critical” while evereything else says “normal”. What does this mean? How do i fix it? Any ideas?
