Windows 7 Crashing constantly, please help!

Hey everyone I am having major issues with Windows 7 install on a new build. This is my fifth PC to put together but my first windows 7, I am having nothing but troubles out of it.

At first I was crashing during install after many many tries I finally got it to install. Now it will either freeze or give me a BSOD while inside of Windows. I tried booting into safe mode and it still does the same thing, generally freezing instead of blue screen. I have changed power supplies, updated bios, installed MSI drivers for motherboard but I can't seem to get anything else to work. Everytime I try and install the video card drivers it will crash and I have to do a hard reboot. I am at wits in and am about ready to start RMAing once piece at a time back to newegg till something works.

Anyways these are my woes and I am hoping that you guys can help me to figure out what the heck is going wrong with this PC.

PC Specs are as followed.
MSI 870S-G46 AM3 AMD 870 SATA 6Gb/s ATX
Microsoft Windows 7 Home Premium SP1 64-bit
AMD Athlon II X4 640 Propus 3.0GHz Socket AM3
G.SKILL Ripjaws Series 4GB (2 x 2GB)
VisionTek 900310 Radeon HD 5670
APEX AL-D500EXP 500W ATX12V Power Supply
ASUS DRW-24B1ST/BLK/B/AS Black
SAMSUNG Spinpoint F3 HD103SJ 1TB 7200 RPM SATA

I have also uploaded the data I retrieved from the dump files I received today.

Oh ok. I am at work right now. I will upload them this evening when I get home.

Ok here are the dmp files that I got yesterday while trying to get windows up and running. Hopefully one of you guys can make sense of things and help me get this PC up and running. Thanks in advance.

Anyone?

Can someone please help me. This PC is being built for my cousin and I would really like to get it working by the end of the weekend.

Ok so I downloaded memtest86 and burn the ISO to a CD using imgburn and alcohol, it looks like files were written to the CD but when I tried to boot off of it nothing happens.

I switched my ram around today and windows stayed up much longer than yesterday but still crashes after a while giving me a blue screen.
