Password Not Recognized Periodically by Win 7 Home

I am running Windows 7 Home Premium on Acer Ferrari 200 (pre-installed). There will always be times where after waking the notebook from sleep, the password will not get recognised. I am very sure password is correct.
The occurance after a number of sleeps and wakes varies. And the only way to get in again is to hard reset. My account is admin privilege and the only account in the notebook.
I have checked the security event log but there is not denied messages.

I have the latest Zonealarm Extreme 9 installed and Bit Defender disabled. All recommended Windows 7 patches installed.

Any advise. Thanks ahead

Hi Richard

Created a new ID but the problem persisted. This time was 4 hours from where notebook sleeps.

I now resort to disable password on wake up as an attempt. Thank.

Try opening a new Account, yours may be corrupted. You may also want to check the event viewer.

How to Create and Use a Password Reset Disk in Windows Vista - the How-To Geek

I have uninstalled the Zonealarm Extreme Security 9.1 that is compatible with 64-bit and has not encountered any issue for 1 full day. I will update further if this does not solve the problem, else you can assume that Zonealarm is the cause.
I have now turn to Microsoft Security Essential.

Hi Rich,

Appreciate your response and I am (as I type) in the process of making a password recovery disk already. I also already have a second profile with Administrator privileges.

I may very well end up following your recommendation to delete the problematic account, however, am resisting that at present, as I will lose many settings, etc, that are not established or accessible under the second Administrator account. Any solutions that don't involve completely abandoning the present problematic Administrator account?
