Brent N asked:

Fullscreen Hulu Freezes my PC.

I have what I consider to be an extremely capable computer: AMD Phenom II Quad core black, running two Radeon 4850s in crossfire mode. OS is Vista 64 Ultimate, 4 gigs ram. However, when I expand video like Hulu to fullscreen, it plays the video for maybe 30 seconds, then the screen goes black. Sound continues to play in the background, but my cursor moves VERY slowly over the black screen, and there’s a 5-6 second delay between moving the mouse and the cursor moving. Then the computer freezes completely, requiring a reset.

Fixes I’ve tried:

Updated all drivers to latest versions. (Radeon drivers, Vista SP2, newest flash version, etc.)

I’ve tried running it in 5 different browsers (Opera, Safari, IE8, Chrome, and Firefox.) All of these are the latest editions, and the freeze happens in all of them.

I’m kind of worried that my power supply might be a bit low for my setup, it’s a BFG 550W. It meets the guidelines for running both my graphics cards, but just barely. However, the computer has been running fine and plays all games fine. Could an anemic power supply cause this video problem?

I’m pretty computer-savvy (I built this one), but this problem has me completely frustrated. Any help would be greatly appreciated.

The most common cause of computer freezes is a corrupt registry.
Corruption within your registry keys, registry classes, and registry settings are the most common causes of Windows error messages.
The Computer registry is a database that stores all of your computer
settings. The computer registry becomes more complex as you use your computer. The more programs you use the greater the chance your
computer registry will develop errors and become bloated over time. Without cleaning the registry on a regular basis it is very likely that your PC will freeze.

Cleaning the Windows registry improves the performance of your computer and will reduce the number of PC freezes. The Registry cleaner cleans the registry and frees up Windows registry space.
Completely clean your windows registry with a few clicks of the mouse

I am having the same problem. I also built my machine: Gigabyte mother board. AMD Athlon II Quad Core processor. 600w power supply. 4 gig ram. Using onboard video.
Symptoms: This usually occurs while hulu is in full screen mode sound begins to sound as if a CD is skipping. The cursor begins to slow down and then the computer freezes. Once or twice there were white and black vertical lines. I have updated flash and bios but still same issue.

Right click on your flash video go to settings and UNCHECK Hardware Acceleration.
