Updated GTX260 GPU drivers - 2 days of BSOD!

Hi all,

I come with my tail between my legs and a begging bowl for advice...and old story on i'm sure :) I have tried everything I can think of and have followed every bit of advice I could find. Here's the story...

I have a home build PC: Asus P6T2 Deluxe V2, 12GB (6x2) identical DDR3, i7 920, 650W PSU, GTX 260 Gainward GS GPU (896MB) in a CM sniper case, Corsair H70 water cooled. It has been running like a dream for 12 months now with only 1 BSOD when establishing a safe & stable OC at 3.6 Ghz with super cool temps all round - the BSOD came after 10 hours running Prime95 @ 4.0 Ghz, so I resorted back to a safe OC.

2 days ago I updated my GTX 260 GPU drivers, from the official NVidia homepage...and all went well, until 4 hours later the PC just crashed to black, no warnings, no BSOD, nothing. It just crashed on it's ar$e and tried to reboot and ever since then it was thrown up a BSOD every single time I try to reboot. Even in safe mode. (for some reason, about 139 reboots ago it did manage to boot up the OS into safe mode, whereby I attempted to uninstall the NVidia display drivers using Add/Remove program and...it crashed to BSOD when it started the process!)

I have tried system restore, repairing, memory tests, all attempts at safe mode booting are failing too. They all fail just after the log in screen. The W7 log in screen loads up fine and I put in my password hit enter then after a varying amount of time (5-60 seconds) the BSOD happens. 1 in every 20 attempts I can see my desktop icons loading before it crashes.

I have had a variety of codes including 0x000000A, 0x000000Ex, 0x0000007x, 0x0000001E and the line 'IRQL_not_less_or_equal...'. I read up on this, but I can't seem to action anything as I can't even get the OS to boot and stay up long enough.

I have updated the BIOS to the latest ASUS release to no effect and everything is set to default. I am at the end of my tether since I use this PC for my work as a photographer, my images are all safe on other drives but all the software I need to edit is on there!

Can anyone offer me any advice? (I don't have a spare graphics card to swap out unfortunately). Thanks in advance :)

ran the .dmp files through MS diagnosis SW and have discovered that ntkrnlmp.exe appears to be a culprit...just trying to work out my next move...

Blimey...I am literally over come with the level of assistance! :)

Never mind, i'm having to reformat a drive and install a fresh copy of W7. I tried uninstalling anti-virus and firewall programs, all the usual mem tests and HD tests, restore, repair, updating the Bios, chipset and GPU drivers all to no avail. Unfortunately I simply don't have the time to find the solution to this mess as I need Lightroom working tonight.

This is the first time i've been completely stumped with windows and it has left a bad taste in my mouth. Time for an Apple, perhaps...?
