Windows 7 stuck on reboot loop just before login

OK so the problem started when I was playing a game and it crashed on a loading screen, I then could only boot into windows extremely slowly so I knew something was wrong.

Since then I have booted into safe mode and done a virus check and it found nothing, I had then done a start up repair multiple times and for one reason or another the system would then reboot just as the login screen is loading.

I have recently de fragmented the drive externally and run a slow disk check which found nothing. I've launched start up repair again which says it's unable to fix the problem and I can't boot into safe mode because it'll reboot.

I should also mention I was having problems with the drive a few weeks ago where I was getting different error messages before booting but I managed to sort that out. If a solution can't be found it would be safe to say the drive is failing.

Here is the bsod when I disabled automatic rebooting along with the startup repair error.

STOP: c00002e3 Security Accounts Manager initialization failed because of the following error: A device attached to the system is not functioning (presumably the hard drive)

Error Status: 0xc0000001. Please click ok to shutdown this system and reboot into safe mode, check the event log for more detailed information.

Any help would be seriously appreciated.

Thanks for the reply, I can't get into windows to do a disk check but I took out the hard drive the other day and did a disk check with another computer and it found nothing.
I'll the system file checker report back

thanks again!

OK I tried the system file checker which found nothing wrong, and I made a bootable USB drive of the samsung utility which ironically gets stuck in a loop that says automatic boot in 10 9... I tried re-download the iso and making it bootable again but got the same problem
