BSOD on Boot

I have a new build (4-5 days ago) which was working fine until today. When trying to start-up today I get blue screen error "process or thread crucial to system operation has unexpectedly exited or been terminated"

The Stop error is 0x000000F4 (0x0000000000000003, 0xFFFFFA800E763AE0, 0xFFFFFA800E763DC0, 0xFFFFF800033868B0)

I have done a little poking around, checked that everything is seated, changed out SATA cable for harddrive, and checked BIOS that Harddrive is set as Master... no luck! I have also tried removing RAM sticks and booting with just 1 of them- tried that 4 times (once with each) and no luck.

I know I am supposed to post the dump report- the problem is that I cant even get into the system to get it!! The BSOD opens even when trying to boot to safe mode.

Hello MikeS71, welcome to SF!

Do you have a repair or retail W7 install disc you can use?
Since you can post, I assume you have access to another PC... can you create a W7 DVD there?
