In League of Legends (LoL) my computer randomly freezes during gameplay. My screen just goes black and my sound card repeats the last sound over and over and i have press restart. Recently i installed Jedi Kngiht 2 Jedi Outcast again and i got the same problems there, but every other game is no problem. My System: Acer Laptop Aspire 5930g with Win 7 Intel 2 Duo T9400 2,53 ghz 4 gb RAM GForce 9600M Gt I usually solve these kind of problems by reading other forum articles but i couldnt find a solution (only many people with the same problem) I can pretty much rule out a overheat problem, i had several diagnostics running during those freezes and no indication there ( no unusual temp spikes in gpu or cpu). Nevertheless i tried cleaning/replacing my fans. I think its curious that it happens with LoL and this really old game Jedi Knight 2 Any thoughts what i can do? Thank you!
