I have a quad core AMD and an ATI 4350 and it plays all SD and HD videos fine as long as it has been rebooted. If I have woken the computer up from sleep all the video I try skips or barely plays at all. Both SD and HD video.
I have my power setting set to "balanced". I am pretty sure it must be related to that but I don't know where to go from there. I am running windows 7 64 bit.
Does anyone have any suggestions??
PS I have updated all my drivers
for my video card
