BSOD supposedly due to driver error.

I recently upgraded my CPU from an e6550 to an e8600. After doing so occasionally when on the internet using firefox I get a BSOD. Windows error report tool is suggesting that it is driver related. I have a Dell Optiplex 755 minitower with the following installed:
-intel e8600 core 2 duo
-corsair GS700w power supply
-2Gb DDR2 667Mhz Samsung Ram(stock) plan to upgrade speed and size in very near future
-XFX ATI radeon HD 5770 single slot
-1Tb HDD western digital Black caviar
-Creative Xi-Fi XtremeGamer sound card
-Linksys WMP600N Wireless-N PCI Adapter with Dual-Band wireless card

After installation I checked my fsb:dram ratio and it's1:1. Then I updated my chipset Q35. Bios was also updated to A20 before installing the CPU. Before the CPU upgrade I had zero problems/troubles while all drivers where upgraded to the latest versions.

Any help or suggestions would be greatly appreciated. Thanks

 

Reseated the memory and graphics card and haven't have a BSOD. It's a little strange that is all it took but I'll take it. Thanks a lot.
