Firstly - go to the 'user accounts' icon in your control panel. Check to see if you can reset your access lvl here.
If this fails, follow the below instructions:
Boot your laptop into safe mode
(Do this by pressing F8 while the machine starts up)
When you have selected 'safe mode' you will ultimately be presented with a variation of your normal logon screen.
Click on 'Administrator'
Once the machine has logged on, go to the user accounts section in the CP.
Reset the privelidge lvl for your account
Restart and log on
Job Done
Note:
I've assumed you are running on Windows XP
I've also assumed that there is no Administrator password.
Don't panic about the 'iffy' graphics whilst in safe mode.
