Is there a program that can scan all my hardware and check for damage? Either one of my components is broken or I have a virus. How likely is it to get a virus if you have AVG Free edition?
 
The computer starts up WAY slower than before since instaling my GTX 670. I had a theory the HDD may be damaged, used WD scanner and did the quick scan and said it was fine. The long scan is HUGE so maybe for another day.
