General Computer Support / Re: A doozie: W7 will not verify digital signature of drivers and W7 updates nogo

Hi Shane, after spending more than 15 hours on this I decided it was time to cut my losses and the customer agreed. He will be replacing his laptop because it cannot be made secure even though I explained to him that using Sandboxie could (maybe) do it. The error was plain: "Windows Setup could not configure Windows to run on this computer's hardware." It was W7 Home Prem 64 bit = both giving the same errors regardless of using the Acer Restore Disks or OEM version on DVD & flash. As far as disk drivers are concerned, the restore disks did install all the drivers but it made no difference, the OEM has the hd driver as well. Regardless of which install, it continued to not recognize the digital signature of approx 3 drivers: video, audio and Turbo Boost from Intel, would not allow any Windows updates or any AVG antivirus updates. MSE would not even install. Yes in one of the installs, I did shut down UAC but it made no difference. Thanks for your time and effort.

Shane & Rolemodel, Thanks for your suggestions. I did as you suggested and burned the image on a usb flash drive. Unfortunately the same error appeared: "Windows Setup could not configure Windows to run on this computer's hardware."  From there I can run Msoobe and enter a profile name and reboot to Windows but the same hell starts over with the lovely BSODs starring luafv.sys. Even though the HD tests perfectly I went ahead and tried another known good working HD and the same error appeared. There must be a defect on this mobo preventing it from properly installing. This is a first for me.

Anyone have any further suggestions?

Hi Shane, yes thanks for replying and send me the link. In 10 years however I can count on the fingers on one hand the times I've had issues with DVD-CD drives.... over 100s of re-installs. This would mean that in addition to the built in DVD drive on the laptop, my external DVD drive would also not be reading both my OEM and the 4 restore disks provided by the customer.

To date, I have passed Spinrite twice and Seatools and the disk seems perfect. I have switched power supplies.
I have run memtest overnight without any errors. I have removed one ram chip and reinstalled and still get the same issues. I plan on purchasing another 4GB DDR3 chip just in case both original chips are bad (extremely unlikely). Once I reinstall with the new chip and get an error I will try a reinstall using a flash drive and that will be my last attempt at repair.

Rolemodel, thanks for the advice. I will do these things and report back. I previously did a chkdsk and memtest for one full pass. I'm not holding my breath however as the client used this OS for a couple of years without any hardware symptoms. It was working smoothly while I was removing the rootkits and other viruses, and I was able to install several programs without any issues. I'm running Spinrite now and will follow with Seatools. As I have an external DVD drive I will try an install from there. And as memtest is not perfect I will likely swap mem sticks to see.

This newly re-installed W7 laptop will not update, and even says the Intel drivers are not digitally signed. Please read below for the background story.

I don't know how much background info on this issue I should provide because I don't want to overwhelm anyone, but I guess it's better to have too much than not enough.
Acer Laptop with W7 Home Prem 64 bit belonging to a customer. He had issues with it and brought it back to the store several times after which they finally replaced the motherboard. A couple years later he started getting popups and that's when I entered the picture. Instead of using the original OS license that came with the PC the store must have used an unattended install that was later declared by MSFT to be not genuine. The customer did not then get all his updates and several rootkits were found and removed. Clearly the MacAfee av he was using did not detect and remove them so I wanted to remove it and replace it with MSE. When this did not work I proposed reformatting and re-installing so he could use the genuine license he paid for. The store he bought it from had lost his restore disks during the mobo so they burnt him a new copy which is what he gave me. I thought this would be a walk in the park...

I made sure to reformat and wipe the partitions to ensure any rootkit presence would be destroyed. I then started with his 4 restore disks that worked until they were installing the Acer drivers and software. It got stuck at installing AHCI driver (2/29 items), and stayed there overnight. The next day I removed the DVDs and rebooted and it seemed to load normally... However whenever I tried running or installing a software it would BSOD Stop 3B luafv.sys. I thought to myself: OK the OS is not loaded correctly so I will just use an OEM version of his W7 Home Prem 64 bit. After again deleting partitions, and 3/4 through the OS install I get an error: Windows Setup could not configure Windows to run on this computer's hardware (?!).  I found what I thought was the solution to this error on tomshardware.com website but no... FYI it was saying to go to a command prompt at that error and then run Msoobe located at %windir%\system32\oobe. Guess what I started getting the BSODs with the finger being pointed at luafv.sys again.

I was able to download the drivers from Acer website and even tried a few of the BIOS updates. Several of the drivers indicated issues on install with Windows saying they were not digitally signed. I turned off the digital signature enforcement temporarily at bootup to install the drivers and everything looks fine in Device Mgr until reboot where those drivers that had signature issues have a Yield sign with exclamation point saying that Windows cannot verify the digital signature... MSE will not install. AVG Free will install but will not update.

I did a file integrity scan and it found corrupted files that could not be repaired. I am attaching the CBS.log.

I've never seen this in my 10 years as a tech and am lost... and a bit discouraged. Any help appeciated.

In any event I am stuck there. I can't give this laptop back in this shape
