I just got an E540 and upon a Windows install, after updating the AHCI driver, the screen glitches out (crazy colors, lines, etc) and the system locks up. After a reboot, during Windows startup, the screen glitches out again and it completely powers off. System restore removes the driver and restores the ability to boot.
I've installed the driver from both Lenovo and a newer one from Intel and get the same result.
Windows has the driver already and I'm not opposed to leaving it the way it is, I'm just really wondering about this issue and would like to eventually update.
This happens on both Windows 7 and Windows 10, by the way.

Thanks in advance!
