Doubled my RAM, now BSOD!

[Ilsimen]

I built this computer over 2 years ago. The original build is as follows:

Motherboard: ASUS M4A78-E
CPU: Phenom II x2 555 BE
RAM: 2x2GB of GSkill DDR2-1066
HDD: A couple of old HD's I had laying around

I ran this rig with onboard graphics for awhile, then added a Saphire Radeon HD 5770. About a year ago, I replaced the old HDD's with a 40GB SSD for my boot drive and a 1TB HDD for storage.

A couple days ago, I decided I wanted to double my RAM to 8GB, so I ordered another set of 2x2GB GSkill DDR2-1066 (exact same part number as my orginal purchase.) This is actually my 4th set of this same RAM over 3 seperate builds, never had a problem until today.

When I put my 2 new sticks of RAM into my computer, the BIOS shows up with 8GB, but Windows failed to load, and crashed to a blue screen (about 7 times in a row.) I pulled the new sticks out, and everything works fine again.

My question is, do you think I got a couple bad sticks, or am I forgetting some setting in the BIOS, or is it something else completely. Although I've built a few rigs from scratch, I'm still a noob when it comes to troubleshooting. Any help would be appreciated.
