I have an HP desktop p6716f - 6G. I used CCleaner a month ago & have experienced 4 blue-screen crashes after watching video replays on Major Network websites; including with my now-deleted Hulu. I'm thinking I may've deleted a vital component or hardware piece. After temporarily deactivating my Flash Player, I've reactivated it. I've scanned for hardware abnormalities but none in Device Manager. Can someone help me, please. Thank You in advance.
