Cant start Windows 7 Ultimate 64bit

[BluerjB]

When i start computer my the mouse and keyboard weren't working.. so after a few restart the computer would only get to the part where the mouse shows then the computer restarts...

Right now my computer works because I'm running windows 7 32bit from a different HDD..

What could the problem be?

thanks

theres nothing wrong hardware wise but I've been told that there was something wrong with my driver signature enforcement.. but right now i cant even do anything when i get to the welcome screen its just reboots. is there a tool that can diagnose the startup. i know there a tool like that in the boot menu but that one didn't help at all.

and if you want i think this should be move to software since theres nothing wrong with my hardware
