TurboB.sys and Impcd.sys are both related to Intel Turbo Boost. You were supposed to uninstall it the usual way via Control Panel > Programs and features (Add/Remove).
Ok, time to round up,
Errors:
BSOD's are caused by either HARDWARE or SOFTWARE. Finally you have updated all the drivers and uninstalled Intel Turbo Boost utilities, as you report. You also report that the hardware tests have detected no errors. Up to you to figure out what causes your blue screens. I would much recommend to set your hardware at its stock values as recommended by the manufacturer. Unplug all peripheral devices except mouse and keyboard. Uninstall INTELL TURBO BOOST utilities. If you haven't, run 10 passes of memtest.
Good luck.
Ok, time to round up,
My Windows 7 Lenovo ThinkPad X201 X-64 system experienced 3 BSOD crashes today, after 6 months with no issues. All three bugcheck codes seem to be for different errors.
I have attached SF Diag output, CPU-Z screenshots, and RAMMon screenshots.
Thanks in advance for any help.

OK, I ran CHKSDK /F and HDDScan for a couple of hours, with no errors, and all parameters well within valid ranges.
I ran HDDScan for several hours on Saturday; it showed no errors or out of range conditions. 3 or 4 stable days before another BSOD this afternoon; Bad Pool Header.
OVERCLOCKING ---> Core i5 M540 @2,53, and yours is 2,93Ghz at the moment.
SET ALL CLOCKS, VOLTAGES, TIMINGS, MULTIPLIERS EXACTLY AS RECOMMENDED BY THE MANUFACTURER.

Check your CPU-Z CPU tab to see how you're doing. The frequency is definitely supposed to go down at idle. For now, it must not exceed the stock value of 2,53.
Test your hardware if the blue screens don't go away:
RAM - Test with Memtest86+ - Windows 7 Forums
CPU - Stress Test with Prime95 - Windows 7 Forums
Video Card - Stress Test with Furmark - Windows 7 Forums
Link Removed - Invalid URL
Run everything at stock values.
Ran DriverUpdate, and applied all latest Intel and Lenovo drivers around 2pm yesterday (3/29). Stable until about 30 minutes ago, when another BSOD happened, with laptop basically "idling" with almost nothing going on and no user interaction at all.
Still putting off the "new HDD and start over again" route, but hoping for an "aha" moment and breakthrough soon.
