Hi,

Did you have crashing and freezing problems prior to the hardware upgrades?

Did you connect the 6 pin PCI-E power connector the the video card?

Try reseating  (remove and replace) the video card.  Be sure that the video card sits down all the way into the PCI-E x16 slot and is level from front to back.

You might also try the latest driver from the NVIDIA web site.

Try this bootable memory diagnostic CD. Download memtest86 iso file and burn it to disk using Imgburn.

The NVIDIA GTS 450 should be compatible with your PC.  It's possible that you have a defective card.
