Windows 7: 64 bit ultimate crashing on loadup

My computer is loading up to the point the windows logo starts to flash before changing over to the chose user screen and then just frezing. I have tried runing the boot fix and it came up as unable to repair, i have tried restoring to most recent restore point and got the same problem. Has no issue booting into safe mode.

Am currently trying updating NVIDIA drivers to see if that fixes problem but just thought i would try here to see if there is anything else i should try

Work through these Troubleshooting Steps for Windows 7

Ok I thought I had fixed it, deleted display drivers and it starts perfectly

Then tried installing new NVIDIA driver and it got as far as black screen with mouse pointer and then screen turned off because no signal (no chime from speakers either)

Tried NVIDIA Beta drivers and same problem

Tried letting the computer auto install drivers and restarted and got it working fine, played Diablo 3 for 3 hours, left computer sitting there in character screen (so not doing anything) came back and it was switched off

Turned back on and freezing at windows logo problem back, tried installing beta drivers and got the same thing

Boots fine into safe mode
Boots fine when drivers deleted

I'd Google the card to see if others have had the problem, and how they resolved it.

If not then try all other available drivers, try without the Nvidia services starting up with Windows by turning them off in msconfig>Startup and >Services (after Hiding all MS services), then if necessary try another video card.
