Frustrating Huh!.....Here's a few more......when you use these, try to do them
just one at a time.......otherwise we won't know which way is up!
Swap to a different Keyboard....ideally with a PS2 lead, just for testing mind you
In BIOS.....Turn Off All wake features if you have them....."Wake on Keyboard"....."Wake on Mouse"
Some of the system files might be corrupt.
To fix this you need to do a automated system scan, ...or a SFC scan
Steps to perform sfc scan:
1. Click Start, click All Programs, click Accessories, right-click Command Prompt, and select Run as Administrator.
2. Click Continue or supply Administrator credentials if prompted.
3. In the Command Prompt window type the following, and press Enter:
sfc /scannow
4. You should see the following on-screen messages:
Beginning the system scan. This process will take some time.
Beginning verification phase of system scan.
Verification % complete.
And here is some reference material to go through......I'm starting to believe that it's a configurable setting as you generally believe as well.....there's a lot of people out there with simular bugs in the last two years with no really common answer......
