BSOD just started

[JaBuLs]

I've gotten the BSOD twice in the last week, seems to occur at random times. I did just get a new video card and 4 more GBs of RAM about a month ago, but I formatted and got all the correct and up to date drivers installed. Other than that, there have been no changes in my computer. The two .dmp files for the two crashes are attached, any help is much appreciated.
