Hello, I have a problem with my pc. Every time i turn the pc on and start browsing the internet or gaming my pc goes black from 0.5 sec to 3 sec and goes back its like a blink first its black then white then black again and its all in few secs. This repeats over and over again and some times even freezes whole screen and i have to rr pc to use it again. The freeze is just a big black screen or a white screen with a sound rrrrrrrrrrrrrrrrrrrrrrr.
Iam using:
Motherboard-Gigabyte-ga-h81m-s1
GPU-Asus Radeon r7 200 series- Asus Radeon R7 260x - OC - 2005.
PSU-Dont rly know the name of its but is 500w ATX
CPU-Intel core i3-4160 CPU 3.60 GHz procesor.
SSD-Crucial M500 1TB
4GB ram by Crucial
Windows 10 pro

Things I tried:
Updating and reinstalling drivers.
Increasing fan speed(I thought the gpu is just overheating)
Changing the monitors

Its happening even when i write this. Please help to fix this

(Sorry for bad English)
