A few days ago, my T500 (Windows 7 Ultimate, 32-bit) crashed and went through a startup recovery process. When it was finally logged into Windows, I was unable to detect or connect to any wireless networks and Google Chrome (my primary browser) was gone. After I couldn't find any restore points when running Windows Restore, I decided to just manually restore the missing components. I was able to connect to the internet via ethernet and reinstall Chrome (albeit missing all of my bookmarks and plugins), but still had issues with the wireless connection. Windows Network Diagnostics returned "There might be a problem with the driver for the Wireless Network Connection adapter," but was unable to troubleshoot the issue.
Windows Device Mangager showed no missing network adapter drivers, but under "Other devices" each of the four items were missing drivers:
I've downloaded a number of drivers, (including several variants of Inter AMT and the Multi Card Reader, as suggested by similar threads), but none have addressed the four missing drivers. All attempts to update the drivers were unsuccessful.

I ran sfc /verifyonly and sfc /scannow; it said there some corrupt files and to check CBS.log. The file was fairly long, and I couldn't really discern any relevant information from it. Ctrl-F didn't find anything related to the driver. I don't know what, if anything, was fixed, but the driver issues still remain.
I've tried to manually delete the old 188.8.131.52 drivers with no sucess. Even as an administrator in safe mode, I still couldn't modify anything. SYSTEM and TrustedInstaller are listed as having full control over the files, and there was no option to change the permission settings (check boxes were grayed out).
Is there anyway to modify those permissions so I can delete the old drivers? Would it helpt to reinstall 184.108.40.206? I've looked for a download online but haven't found anything yet. The only other solution I can think of is reinstalling Windows 7. Does that sound like the right course of action? The wireless card and the other drivers haven't had any issues up until now. It seems like some system files were corrupted when it went through the startup repair that started all of this.
