a. Windows + R
b. msconfig
c. Boot - Safe mode - minimal - OK - Restart
2. Uninstal drivers
a. Right click on My Computer
b. Devices
c. Uninstal Graphic and Network drivers - it can be one of them
Try to uninstal all possible drivers
d. Restart PC
3. Return from safe mode
a. Windows + R

After restarting download and install the proper graphic driver for your computer
