BSOD More frequent after new ram install

Hey guys, new here, found site through google
I have a serious problem here, I bought this laptop less than 1 year ago at best buy.
Its a Toshiba Satellite M645, Windows 7 home premium 64bit, 4gb ram (When i bought it), 500gb hdd, core i5 cpu.
Ever since i bought it I've had BSOD's about once a month, didn't bother me too much, never found out what the problem was. Last week i bought 8gb of ddr3 memory to upgrade my laptop, and ever since i installed it I've been getting BSOD's several times a day, it happens randomly, when i'm browsing, playing a game, listening to music, watching a movie etc. So what i want to know is if the new ram i installed is defective so i can return it, or did it make the previous BSOD's worse (when i had 4gb installed).
The exact memory type i installed is this PNY Optima MN8192KD3-1066 Notebook Memory Kit - 8GB (2x4GB), PC3-8500, DDR3 1066MHz at TigerDirect.com
I will be doing a RAM test with memtest86+ shortly, but since i had a BSOD problem before i installed the new RAM i decided to post my dump files first. I hope i did everything right, first time doing it.
Thank You :)

first pass of memtest resulted in 5 errors, going to continue testing ram sticks individually to see if the problem is with the ram or mobo slot.
