New Build Hanging/Hard Locking

I just put together a new build yesterday. Everything was running fine, but the system consistently freezes when I try to stream 1080p videos on youtube at full-screen. What happens is basically my computer just goes black for like 10 seconds, and then white for 10 seconds, and some times i see parts of my desktop. I can see my mouse but I can't move it. (When I try to move it, it takes like 10 seconds to show on the screen.)

Though it does work if I turn "hardware acceleration" off on Flash settings. Note that I was able to stream 720p videos at full-screen and 1080p videos in window mode fine, even with hardware acceleration.

Here is my build:
OS: Windows 7 Professional
CPU: Intel Core i5 2.66Ghz Quad-core
Motherboard: GA-P55M-UD4
GPU: Sapphire ATI Radeon HD 5850
PSU: Corsair 750 TX (Should be more than enough for my components.)
SATA harddrive on AHCI mode.

(It is also playing games at max settings fine.)

Also, my monitor's resolution is at 1680x1050.

I've ran MemTest for 2 passes and it was fine. (I'll run it for 7 passes later tonight.)

CPU and GPU temperatures are also pretty cool (20-30 for the CPU, 30-40 for the GPU).

During the hang, I am getting a bunch of these messages in my event viewer:

It also went to a BSoD last night, but I am no longer able to reproduce it. I'm really stuck and any help is greatly appreciated! Thanks in advance.

You are experiencing one of the many problems ATI has been having. Do a google on "ATI grey screen" and you will see tons of them. Try updating to the new ATI 10.3 drivers and see if that handles your problem.

Thanks for the advice. My graphics driver is already at the latest (10.3). This is probably a bug with ATI or windows 7 as I got the same hardlock when I tried to stream a 720p video fullscreen when I set my desktop resolution to 1152x648.

Seems to be a bug with flash displaying a resolution higher than the resolution I'm setting. I probably shouldn't worry about it right? It doesn't seem like a hardware issue.

If its flash you may need to update flash (assuming its not set for auto-update).

But flash is not exactly a robust client and trying to interpolate different resolutions probably is making flash go bonkers.

My flash is already fully updated. I will look around more to see if anyone else has the problem. Thanks for the replies!
