User Account is disabled

[amission]

Have had this machine over a year, 3 weeks ago, I started getting a random message that my account has been disabled, contact system admin.

Well, that's me! started in safe mode, enabled the administrator account (no password) then tried to login as Administrator....SAME MESSAGE!

Rebooted a couple of times, was able to finally login as my user account: GENE (who is an admin as well)

Double checked security profile to ensure *something* hadn't set that - nope.

I then used the system restore DVD to do a restore anyways...

Things have been fine for about 2 weeks, but then this morning..same thing.
Tried to login as user GENE (an admin account) received the message, your account is locked out and to contact system admin.. After enabling Administrator through safe mode command line, I rebooted into Administrator fine. When I go to the Control Panel, user GENE is not there, however the user profile exists AND the files are there under c:\users\gene\

really really weird

System: Win7 Pro, SP1, Alienware, Intel i7 12GB ram, 64bit workstation - no domain

help!

Ok, I followed this thread http://www.sevenforums.com/general-discussion/157552-admin-account-disabled.html
and re-enabled GENE, but why the heck does this happen in the first place?????
