Blue Screens and Game Crashes

I just built a new machine and did a clean install of Win7 RC last week. For the most part it runs like a dream, very much up to par.

However, there are occasional Blue Screens and game crashes that happen while putting little strain on the PC, in my opinion.

My Machine:
Intel I7 920
GIGABYTE GA-EX58-UD3R MoBo
Geforce GTX 260
6GB G.Skill DDR3 1600
260GB Seagate Barracuda HD

I am typically running Firefox, Ventrilo and World of Warcraft when the issue occurs. Occasionally I get dips in my frame rate from around 60fps to 15-25fps. I received a notification that it was in relation to my video card and that I should update the driver, however I installed the 185.85 nvidia driver when I assembled it all.

Is there anyone that has experienced similar issues? if so what was your fix?

Thanks for the time

Check the event viewer logs for info, under windows logs. Type event viewer in the search box on the start menu. It will show up.

Also, posting as much as you can about the information in the bsod such as error codes and descriptive line can only help figure out what is causing them.

I will post those as soon as i get back to my home PC. Being at work restricts the amount i can post about the issue, my appologies for being vague.
