I just recently installed Windows 7 Home Premium 64-bit on my desktop computer. I had had 32-bit installed and working fine, but I decided to reformat and throw on 64-bit for increased performance.
Unfortunately, when I finished reinstalling the OS and compatible drivers, I noticed something strange in my system logs and in my device manager.
In the device manager, I have this error message for my processor:
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 might be malicious software from an unknown source. (Code 52)
I right-clicked each processor entry for my Intel i5 processor and clicked on Uninstall
. After doing so, I click on Action -> Scan for hardware changes...
Then all the processors reappeared, with the same error message as before.
In the system logs, I noticed warning messages errors for event ID 219, source - Kernel-PnP
The error message for the event is:
The driver \Driver\intelppm failed to load for the device ACPI\GenuineIntel_-_Intel64_Family_6_Model_30_-_Intel(R)_Core(TM)_i5_CPU_________750__@_2.67GHz\_0.
I tried downloading the latest driver chipset from Intel and installing, but nothing has helped me. I am having strange issues that I did not experience in Win 7 32-bit:
- Digital output from my Soundblaster Audigy is intermittent
- Desktop Manager (Aero) stop working and the theme changes to the basic
appearance. Then after 1 - 2 minutes, switches back to Aero. I looked in the
logs and also saw that some application had caused Aero to stop working.
Oh, I also have Microsoft Security Essentials installed. I'll uninstall that and see how she runs without anything else running in the background - other than Windows processes.
Curious if any of you have seen this issue before and what you had found as the solution.
