Wdfldr.sys 0X7E Bsod.. Please Help ..!!

[ashwarsadh]

I have a Windows Server R2 64 bit . It was running Fine till Yesterday, but Microsoft Excel Stopped opening suddenly, it started getting updated and gets failed everytime. So, I restarted the PC and it stopped booting up, it just restarts after a Black Screen.
I tried Safe Mode, but It loaded all drivers till HWPOLICY.SYS , so all Drivers were being loaded and then it just restarted. I tried doing Startup Repair, Chkdsk , sfc etc. but nothing helped..!
When I tried Disable Restart on System Failure Option I Got Following BSOD (0x7E):


After researcing google for 6-7 hours I found only one Resource on this :
