Question FM2A88X Extreme6+ problem

[M_G_M]

Hi everyone,
I have a problem with my motherboard FM2A88X Extreme6+ .
The system starts normally until it starts booting Windows. (Windows 7 pro 64 ) Windows starts to load normally and after a few seconds the monitor turns black and starts flashing. The system continues to work and does not display any errors on the motherboard. The only way to stop it is to unplug it. When I enter into the BIOS, this problem does not exist. The monitor works without a problem. I appreciate any help. Please!
What I use: CPU - AMD A8 6600 series,
RAM - Corsair DD3, 2x4GB, 2400 MHz
SATA SSD - 120GB
video - onboard
Power - 600 W
