hi i have got a inspirion 1525 laptop and i cant remember the password for dell account so i have had to do another account to get into the laptop but i cant uninstall any programmes as im not the administator

Do you mean your account with Dell, or your account on the computer? It sounds like you forgot the password for the admin account on the computer. That may not be recoverable. I've had clients with similar problems when an employee that was subsequently fired had changed the admin account password. We had to remove the drive, use Linux to mount the drive, copy the data to a backup thumb drive, and then reimage the system completely.
