Intel HD driver BSOD

[HammerSandwich]

I've seen this on 2 PCs lately, both Acer Veriton X480G, running Win7 Pro x64.

The PCs boot normally & run for a few minutes before BSODing in the Intel storage driver. Both PCs run fine in safe mode. Also, both PCs worked for at least a few weeks before the problems started.

First PC's BIOS was set to RAID, even though it has a single HD. I switched to the default Win7 driver & had the exact same behavior. I tried the latest Intel driver & had the exact same behavior. Next, I used devmgmt to uninstall the HD & controller in safe mode, switched to AHCI in the BIOS, booted & installed with the MS driver. This caused the PC to fail while booting Windows. A full Windows reinstall worked perfectly, running the default driver.

Second PC's BIOS showed AHCI. Crap! I didn't even try further debugging, just reinstalled Windows.

Questions:

1. Has a recent update caused HD-driver problems?
2. How do I switch a Win7 boot drive's storage mode without reinstalling?
3. Something funny about these Acers?
4. What am I missing here?

Many thanks.

No one?

revert back to the previous driver or install a newer one

Think I tried both...

boot the machine to safe mode and then delete the intell storage driver and then reboot machine. you can also delete the hw local machine key as a last restor and that will force windows to redetect all hardaware.

I've tried the 1st but not the 2nd. Need a 3rd PC to act up now, so I can test that angle.

Thanks.
