I i recently been getting this werid crash for my games, i could be playing then all of sudden it just crashes to desktop. it's followed by a error message that this application has crashed. If i were to try to replay the game i get, flickering, werid sound noises and then followed by another crash. This happens to any program using direct x i believe, youtube, flashplayer and even my internet search engine is messed up after that one crash.
Heres an example

Did this issue happen all of a sudden or did you do any upgrades prior to the PC crashing?
