I also have the same problem of your part before. It's a problem with ati hd 5670 card , but only watching videos not gaming. Then I use VLC player and chrome browser because it's ok. Somehow gfx not the same, so can u detail your specs?.

I have built a new system because the problems can't be solved. The old system which has problem was replace with NVidia gt 520 and good now for my sis.

Checked!

Your CPU not compatible with current mobo because this motherboard support upto AM2+ only not AM3.

AMD Phenom II X6 1045T = Socket AM3

These issues cause u are not read manual before upgrade.
