9400 gt is hanging computer in youtube or any online streaming

[b]Hi, there

[/b]

        I have a complex problem? I've tried youtube without  installing driver of nividia geforce 9400gt, and it is working. And when I install it's driver it hangs my computer in one second in youtube or matacafe or any online streaming sites.

when I plug out 9400gt. My mother board (DG43NB)'s vga also works well, wheather it’s drivers are installed or not.

I’ve upgraded 9400 gt’s driver but it’s also in same position.

So, I’ve no any idea. wheather there is my software problem or my hardware problem.

please tell me it’s solution please.

Try and disable your on-board VGA in the BIOS and uninstall the Intel Graphics drivers then install the nvidia graphics drivers. The whql drivers is here: http://www.nvidia.com/object/winxp-258.96-whql-driver.html
