I have a HP Pavilion Entertainment PC and when i play games such as TF2 or even minecraft my laptop crashes after a while. And i Know its not a visus because i have (titainum Maxium security) done full scans on my laptop at least 5 times. they take 5 hours each time. the strange thing is that its only been happering the last 3 months or so. ITs getting worse because i was watching a youtube video today and my laptop just crashed. when my computer crashes its somrtimes a striped screen or blue or even green. some one please help
