Which specifically? IIRC some are very heavy.
I watch DVD's and the o/b graphics ( Nvidia Geforce 8200) w/256mb memory gets hung up occasionally
Then turn off GPU video acceleration and use the CPU only.
and has resulted in BOSD more than once.
huh? aren't you using Windows 7 64bit? With windows vista and windows 7 the computer will reboot the video card if it crashes, it should not cause a BSOD... Do you even use a video player that uses the onboard GPU for video rendering acceleration? most do not, I would suspect a CPU, RAM, mobo or PSU problem if it causes BSODs. If that is the case then enable GPU acceleration might make things better... go try

I need a PCIE card preferably 1Gig memory.
If you don't do any gaming, why do you need 1GB of memory?
I had purchased one from Tiger Direct a Sparkle Geforce 8400 1GB DDR3, which rendered my PCI audio card useless even though there were no known conflicts I could fine (Worked on it for 2 weeks).
PCI audio card? thats a red flag right there... is it a CreativeLabs audio card? Creative is the PLAGUE! get rid of it! burn it in a FIRE!
Seriously creative has the worst, most unstable, most shittiest drivers ever made. Always had... they make nice hardware but their drivers are so bad that using it is unacceptable. If you are having BSODs and using a creative audio card the first thing I would do is unplug that sucker... use the onboard audio, its more then good enough.
