DDR3 Video RAM is different than the motherboard RAM. They are both completely separate systems.

And yes, it will run in your system, this 5450 uses very low power.

go into safe mode (sorry it was boot mode, but I meant safe mode) and have you updated the driver?

If that doesn't work, do you have another PCI slot you can use?

I think he needs to down load the AMD drivers and take out the nVidia drivers and he might have to disable his integrated GPU. Just a thought

Go into your BIOS once

You restart your computer, as soon as it starts booting press F8 or the delete key. It should bring up your BIOS screen. Then you move around with your arrow keys, Enter (selects a menu option), ESC (go back out of an option). You have to find something that that says Display or Graphics Display then change it to PCI as primary display, after that to save it might be F10 (not too sure on your BIOS). Also, find integrated graphics if it has it and disable it, if it's there.

DDR2 is your board's RAM slot it doesnt really matter when they are diffrent so yes you can use it

Okay, just being extra cautious. Hmm, is it possible for you to try the card on someone elses computer? It may help figure out if the card has problems.

Yeah if you tried the drivers and disabled the integrated GPU or just disabled it. How did you get the new AMD drivers in? Did your GPU come with a disk? If you have covered all that then I would do what fantastik said try the card in another rig.

Your card might be bad. I have another question what games are you planning on playing with that card? But first lets get you up and going. Let us know what you have done so far.
