Games freeze on new computer.

Hello! 2 days ago games like (GTA 5, HITMAN Absolution, Dying Light) started to freeze 10 minutes after launch. Namely, they hung on the last picture, but the sound was heard only the picture hung tightly. I checked the temperature, neither the processor nor the video card overheats, the latest firewood is installed. The computer was bought just a week ago, as before this was not the case, it was checked for viruses by Kaspersky and Norton, the system is completely clean. Computer configuration: Video card AMD Radeon R7 200 series, Processor AMD a10-7700K Radeon R7, Motherboard Asus Socket FM2+ a88XM-A, RAM 2x4GB, Win7
