Windows 7: BSOD upon boot up IRQL_NOT_LESS_OR_EQUAL

BSOD upon boot up IRQL_NOT_LESS_OR_EQUAL

I bought a Lenovo B570 laptop the other day. First thing I did was pop in Windows Ultimate to give it a fresh install without all the bloatware. Windows installed fine, and then I start installing the drivers. The first time I just let the drivers install via Windows Update. Windows Update finished and then requested a reboot. I rebooted and it gives me a BSOD right after the "Starting Windows" splash screen.

I launched startup repair and reverted back to a system restore point before the Windows Updates. Boots up fine. Reinstalled the drivers but this time from the Lenovo site. Same thing, BSOD.

So, it seems to be something to do with the drivers. But what the heck am I supposed to do to get around that?

Here is the entire BSOD:

You'll need to go into safe mode and post us the dump files so we can examine them. http://www.sevenforums.com/crashes-d...tructions.html

Hello, I've recently had a BSOD with the IRQL_NOT_LESS_OR_EQUAL error. I've had this BSOD a couple of times in the past, but after I rebooted it was alright. However today every time, shortly after I log in on Windows, this BSOD pops up. I've attached the BSOD report. Thanks for your help

BSOD on boot: irql_not_less_or_equal
When my PC boots, I *usually* get irql_not_less_or_equal BSOD. Sometimes it boots successfully (maybe 1 in 15 or so). Safe mode seems to work OK, so it must be a driver or similar. I have attached the SF Diagnostic Tool zip file. Many thanks in advance for helping me out !
