I have a Toshiba L50-B-1P1. It has 1TB hard drive, 8 gb Ram, 2 gb AMD Radeon R7 M260. Games such as Dirty bomb and Dota used to work fine with around 50 fps. My laptop had a hard drive problem, it wasn't turning on. I sent it to the repairing dude. He fixed it and everything else is working fine except games. Fps now fluctuates between different points in the game. On the main menu its 60, but in game it falls to 10 or 5, it lags alot. It has windows 7 64 bit. All drivers are updated. This problem started since the hard drive issue. Any ideas how to solve it.
