Windows 7 shutdown Doesn't turn Off PC

[vackillers]

Been having shutdown issues for the last several weeks following some issues i was having with an SSD drive and after a few hours of some hard soul serching in safe mode boots, i figured out that its an Nvidia driver that stops the machine from powering down after i hit the shutdown on Windows 7, i've tried reinstalling old drivers as well as the latest ones but i still get the same issue, it shuts down and powers off just fine NO PROBLEM!!! when i uninstall the nvidia drivers, but the second i load them back into windows i get the same problem again, if anyone has any thoughts or solutions i would really apreciate it, i've been trying to sort this bloody mess out for 2 weeks or more, and finally got it pined to the nvidia drivers.

Spec is : Phenom II X6 1080XT / 8GB DDR3 1333 / 2 EVGA GTX 560 Ti's in SLi mode/ 1TB 7200RPM HDD / ASUS M4N75TD Motherboard / BFG 1000WATT PSU / Using Antec DF-85 case


I've done bios settings and cleared the bios completely, nothing is overclocked, everything is at factory defualts, i've tried updating the bios , and i've also disabled the SLI mode and nothing effected it, and also done several install of windows. One last thing, it shurts down and turns off perfectly fine in safe mode.

any help pls would be apreciated

PS. The IEE host bus controller in device manager tweak doesn't work, it doesn't matter if the power saving box is checked or not.

Did you ever check for firmware updates for your ssd?

Many of them have functionality updates for their firmware.

yes the firmware update was the very very first thing i did with the SSD, 2nd thing was a secure wipe of it

Hmmmm, You Should Take this up With the NVIDIA Company and get a refund or a new PC, What Video card and What Driver also What Version?
