Hi there! I want share my problem with you. I upgraded windows and and everything seems ok, but! Suddenly after default driver instalation (AMD Catalyst 03.00.0808) from my manufacturer, screen started to flash. I tried restart, but it doesnt help. I just reinstall Win 8 5th time because of this.

I need help to find some solution for my video card. I have switchable graphics (AMD 6650m + Intel 3000)
I found new Catalysts, but nothing seems to work. It just doesnt distinguish that AMD. Intel works.

THX for reply.
