I just installed a Maxtor OneTouch 4mini hard drive and the computer wouldn't allow me to eject it, there were no options available to eject it. So i just turned off the computer before taking it out. So i took it out and now,whenever i turn on my computer it works fine.
But, when i try to turn off my computer it just turns itself off and then after a few seconds it just restarts. In the end i have to press the power button to turn it off. I tried using system restore, but it wouldn't work and cleaning up my registry didn't even help.
