This seems to happening a lot at the moment!
From experience it can be a number of things, the worst being a failing hard-drive These imacs are now at least 6 years old and unfortunately HDs don't last forever anymore.
Try starting up from your install Cd and run the disk first-aid found in the utilities menu. Does it fix anything? does the Mac now start up properly. Also while you are in the utility, look to see how much free space is left on the HD. You should have at least 10% of the HD's total capacity free. if not then the system has to work overtime and that invariably invokes the beach-ball.
If the utilities found nothing wrong and you do have plenty of free space then the next thing is to do an "Archive & Install"
This will reinstall the system software which may have become corrupted. The down side is that you will have to run all the updates that you already had done all over again.
You have got everything backed up haven't you?

Rainbow vacuum

Sounds like the other owner did not take care of it. If it sat with water in it, then the motor could have big corrosion issues.

Hi i have forgot my parent password on my home access toshiba laptop so now i cant do anything how do i recover this or put my laptop restore please help

A Windows password reset bootable disk could do all the job for you, it can reset your forgotten or unknown Windows password safely and quickly without login, you can create one with the tool Windows Password Breaker, then use it to reset your password.

I need to change the password on my acer aspire 6920

If you are referring to the BIOS password, you may reset the password by removing the CMOS battery.
If you are referring to the Windows Login password, please follow the below steps:
you may crack(reset) the password by using the "Ophcrack" Application.
Ophcrack is a free Windows password cracker based on rainbow tables. It is a very efficient implementation of rainbow tables done by the inventors of the method. It comes with a Graphical User Interface and runs on multiple platforms.
You may download the Application and burn it on a Disc.
Once this is Complete, insert the Disc in the Computer.
restart the Computer and select the CD/DVD Drive as the primary Boot device from the Boot options menu.
then, follow the On-screen instructions.
This will automatically reset the password without deleting any personal Data.

E2 Rainbow vacuum motor protector

Some possible ideas:
Make sure the cone shaped air impeller does not have hair/thread/fibers wrapped around it. This will cause the motor to work harder, and trip the protector.
Make sure you are not overfilling the vacuum with water. If the water is touching the impeller, that will also cause it to move slower, and trip the protector.
Other than that, i'd have to examine it.
Hope that helps!

Acer Aspire M1100 Desktop - lost password, can't login in User Login. Is there a way to bypass the password?

If you're having trouble logging into Windows, you can attempt to use the Administrator account to edit/remove the password of the user login. The Administrator account is hidden by default while in normal mode. You'll need to boot the PC into Safe Mode and login as the Administrator account. Follow the below steps:

  1. Reboot the PC and before the Windows boot screen appears, tap the F8 key about once per second.
  2. Eventually you'll be faced with a screen asking you how you want to boot Windows. Select Safe Mode.
  3. You will see some dll, sys, and com files scrolling down your screen, this is normal. Eventually the PC will boot up and you'll have a login screen with your User Account(s) and a new account, Administrator. Select Administrator.
  4. As long as you haven't, in the past, altered the password for the Administrator account, you should be able to simply click this account and have it log you in. If it requests a password, you might try "password" (without quotes) for the password.
  5. Once in, Navigate to Start -> Control Panel -> User Accounts
  6. Select the User Login information that you're not able to log into and remove the password for the account or change it something you know.
You can now reboot the PC normally and be able to log into this account without a password or with the password you created.

Rainbow effect has more to do with color wheel style and speed.
