BSOD 0x0000007B

Hi all,

I am having problems with my Thinkpad T500!First off It's been having problems installing the most basic of drivers.

I went to the Lenovo site and downloaded all the most up to date drivers. On doing this and installing some updates from Lenovo it has caused me real problems! My laptop gets to the windows screen just before the log on prompt it then freezes and gives be a BSOD message then reboots. I then get the repair windows option or just boot to windows option, I tired the repair and it doesn't seem to work. I've tried a chkdsk /f chkdsk /r and that reports no problems. I then tried the SFC/ SCANNOW command and it gets to 30% and says windows could not start the repair service! The only way I can get back to Windows is via the F8 option then using last know good configuration I've used this option to get back to Windows and get the SF Diagnostic tool and get the dumps.

I am running Windows 7 Professional 64bit OEM Edition. I have no recovery CD as this as it came preloaded on the laptop. I hope I am not up the creek without a paddle on this!

Any help would be greatly appreciated. I have attached the SF Diagnostic dump
