New build, OS load issues

Long time lurker, second time poster, first class nublet.

This is my first custom PC project and, though proud though I am, I know when I ought to ask my elders.

So here's the thing: Brand new build, just created yesterday and everything boots up just dandy and all seems to be going smoothly until I hit the Windows 7 splash screen. As soon as I hit the splash, BSOD for maybe half a second before the computer auto-restarts. It goes to BSOD so quickly, I can't even go into safe mode.

So, here's the build:

CPU: Intel i5 750
MOBO: Gigabyte P55M-UD4
RAM: G. Skill Ripjaws 4 GB (2x2GB) DDR3 1600
HDD: Western Digital Caviar Green 750GB
PSU: Corsair 650TX
Case: Antec 300 Illusion
OS: Windows 7 32bit RC 7100
and oddly enough..
Video Card: nVidia 8600GT, 256MB

It's also important to note that I have actually been able to perform system recovery attempts just fine--it's just when I try to run the OS normally, it dies on me.

The drive runs just fine on other PCs: I installed Windows 7 on the drive from another computer (which is now scrapped).

And the OS load problem persists with all drives with all SATA drives. I connected a Hitachi Deskstar 250GB with the same Windows 7 build and I still can't load the OS but I can load the system recovery. On IDE drives, however, I connected a WD Caviar Black 160GB with Windows XP Home 32bit SP3 and everything loads but I can't use my mouse nor my keyboard.

I've also tried running the rig with just one RAM stick and I get the same problems. I haven't tweaked with the built in MOBO settings either.



I need tickets off this failboat, friends. Help me out.
