I've activated again the Enable memory protection to help mitigate online attacks in the IE8, and it works ok for a while. Then the Bugchecks come agian.I've activated the driver verifier again, but this time with the all drivers option. After restart the computer and ask for the user/password, the computer goes to blue screen with this message:IO SYSTEM VERIFICATION ERROR IN Wmiacpi.sys (WDM driver error 20e)
