Random BSOD today

[BSODequalsTEARS]

So my computer was completely running fine and when I turned it on today it brought me to the Windows Error Recovery screen. When I choose the option of Start windows normally the BSOD flashes and restarts. If I choose the launch startup repair option, it runs fine but my keyboard and mouse stops functioning and I can't click any options. This is also the case when I boot my Windows 7 DVD for repair. I get stuck at the language screen on windows 7 boot menu with my mouse and keyboard not functioning. The mouse and keyboard stop functioning right before each of these two "fixing scenarios" load. The last software that I installed was Itunes. It was working with Itunes for about a week until today. I also tried getting windows to safe mode which it didn't. I'm just absolutely confused with which options I have left.

Running: Windows 7 Ultimate x64
My computer is custom built:
Q6600
6GB G-Skill RAM
Corsair 650W
EVGA Geforce 7800GT
Soundblaster X-FI
Western Digital 74GB Raptor Hard Drive

Again everything was working perfectly fine until today. I took a quick picture with my phone to get the BSOD error:

"STOP: 0x0000007B (0xFFFFF880009A9928.0xFFFFFFFFC0000034.0x00000000000000000x00000000000000)"

Any advice or help would be great!
Thanks!

Hello, and welcome!

It seems this is a hardware problem; let's start off with some hardware diagnostics right away.

Run Memtest86: http://www.sevenforums.com/tutorials/105647-ram-test-memtest86.html

Also, run SeaTools for DOS, to test the hard drive.
