Cannot Boot Windows Except with "Disable Driver Signature Enforcement" Option

Anonymous

I installed the lates ATI drivers on the computer in July and since then I have been unable to boot the computer except by using the option in the title. If i boot windows any other way, including the three Safe Mode options, all that happens is it crashes and then loads the Windows Startup Repair. However this sits there saying that it is attempting repairs for several hours and then asks to send information to MS - at which point the &*%$ HP recovery software kicks in and prevents me from clicking the send button.

I tried running system restore back in July but I was unable to restore the system for reasons which I cant work out, I just get an error message saying "Restore could not be completed, the system has not been changed".

I have recently installed the latest ATI drivers (10.8) and that hasn't helped, nor has installing the drivers from the manufacturers website (HP Touchsmart TX2-1340ea).

In device manager there is no Yellow ! and Windows reports that the drivers have valid signatures.

I am wondering whether uninstalling the drivers back in July removed another driver that I hadn't noticed. Is there a program or tool available from Microsoft to scan for drivers that are corrupt or have improper signatures to help me locate the problem driver?

Hopefully someone will be able to help, as I am currently at a loss, and would very much prefer to not have to use the recovery partition to reset the laptop back to the way it was when I bought it.

    I have managed to get it to boot in Safe Mode by using msconfig, and then selecting Disable Driver Signature... from the F8 menu. From that I managed to work out where the problem possibly lies. This is an extract from ntbootlg.txt from before getting Safe Mode to work but after the problem began:

    Loaded driver \SystemRoot\system32\DRIVERS\pciide.sys

    Loaded driver \SystemRoot\system32\DRIVERS\amdide64.sys

    When booting Safe Mode the loaded drivers stream by and then it freezes at PCIIDE.sys . This is where it crashes when booting normally. After about 30 seconds after it freezes, with Disable Driver Signature Enforcement option selected, the next device is AMDIDE.sys , then AMDIDE64.sys

    Could this be where I am having problems, and if so how would I go about fixing it? (According to sigverif.exe amdide.sys has a valid signature)

    Hi TCWORLD,

    I suggest disabling your anti-virus temporarily and attempting to reinstall the drivers.

    You need to uninstall the anti-virus temporarily to fully disable it, provided you have the means to reinstall the software afterwards.

    8.632.0.0 is the current driver version installed yes. I found the sigverif.exe tool and ran it, but the only unsigned signatures it found were the modem driver which has been reinstalled from win update  but hasn't fixed the problem, and a file called wdfcoinstaller01009.dll, which doesn't seem to exist in the directory listed by the tool.

    Just to be clear, did you install Ati drivers provided by HP, version 8.632.0.0? and if so in Device Manager under Display Adapters do properties show this driver vesion?
