win 7 64 bit freezes when watching video in explorer, firefox, or chro

Also I assume this is a desktop with integrated graphics, have you tried an add-on card to see if that helps?

Also, since you are sharing with system RAM, I would check in your BIOS to see if there is a setting to limit that, sometimes there is. (Limit the amount of System RAM that is used to VRAM).

HI
it is a desktop but it has a separate graphics card
nvidia geforce gts 250 video
I think the card has 1gb of memory
Will check the bios
thanks

If it is an add-on card, BIOS won't have settings for it.

What brand did you get? I know it is Nvidia, but who is the manufacturer of it? PNY, MCI, Evga, etc...

Keep us updated, I haven't heard of Evga having this issue, they make pretty good cards.

Have you tried backing up your files, and possibly doing a clean install of Windows?
