Problem with Windows 7 PC failing to start after turning off driver signature protection!
Problem with Windows 7 PC failing to start after turning off driver signature protection!
Good day,
I am using a Windows 7 Pro 64-Bit system with an Intel Core 2 Quad Core processor. I recently installed the Sound BlasterX AE-5 Plus and the latest driver package AECMDMasterInstaller_3.4.92.00. However, I encountered an issue in the device manager:
"Windows cannot verify the digital signature for the drivers required for this device. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that could be malicious software from an unknown source. (Code 52)"
The Sound Blaster only functions correctly with the standard Windows drivers.
To temporarily work around this, I disabled driver signature enforcement by pressing F8 during startup and selecting the option. This did not resolve the problem.
I then permanently disabled it from the command prompt (CMD) using the command:
"bcdedit.exe /set nointegritychecks on" and rebooted. Still, the drivers failed to install.
Later, I re-enabled the restriction with:
"bcdedit.exe /set nointegritychecks off" and restarted.
But a bigger issue emerged: the PC no longer boots normally. It repeatedly enters startup repair mode and attempts to fix itself, but the error persists.
The only way to access Windows is by pressing F8 during boot and choosing the same option.
I removed the Sound Blaster card, uninstalled all recent drivers, and used CCLEANER to clean the registry, yet the problem remains unresolved.
Any suggestions would be greatly appreciated!
Thank you in advance!
