Crashes the video driver.

Good day to forum users. The fact that I have a 2011 laptop (ASUS K53TK-SX075V). Some two radeon 6520g and radeon 7670m. When you load cs GO and start the stress test in furmark, the screen displays artifacts and crash the driver. While loading the GPU to 99%, and the temperature in the region of 50-60 degrees. Install the new driver gave me a BSOD. Reinstalling Windows is not an option.
Please help!
