Videos cause sudden lockup on Windows 7 64 bit.

[jpesh]

Hello,
In all browsers I try to stream videos from youtube, facebook, etc. All of them cause sudden lockup of browser, including the mouse not being able to move. I have an ATI 5450 graphics card and have downloaded most recent Catalyst Control Center and updated Java/Directx/Flash.
The computer is stock from Dell with i7 processor and 8 gigs of ram. Any help would be greatly appreciated, as it seems to me that Dell has no f***ing clue how to fix it.

Maybe it is cause your cookies are disabled, delete all history, and uninstall Flash and reinstall. You might have a registry error or virus too. Try deleting you cache/history first.

It only happens in browsers ?

Well, the GPU is probably doing most of the work, so my suspicion lays there first and formost. Could also be RAM, but I'd be expecting BSOD's instead of lockups...

I've tried deleting history, checked that cookies are enabled and have no viruses.. the problem is that the computer is totally stock and practically brand new and this problem has occurred since purchase.

What kind of PSU do you have?

Disable your Flash hardware-acceleration in your Firefox's configuration.
