BIOS passwords are used to add an additional level of security to your machine. Without the correct BIOS password, your Dell Optiplex 745 will not complete the boot process. The password can be reset whether you know your current password or not.

Navigate to the "Exit" screen. Select the "BIOS Password" setting. Enter your BIOS password and a new password if desired.

Hello,

To remove the side of the Dell Optiplex 745 cases you need to push the release latch on the back either top or side depending on whether it is a tower or a desktop. The latch just slides back and the side will release and the cover will pop loose. The normal issue with this model is not a bad video card, it is bad capacitors on the motherboard. We repair these boards all the time for a federal prison that is located near our office. Look over this guide we have posted on our site that explains what to look for and what to do about it. http://www.ccl-la.com/blog/index.php/dell-optiplex-745-repair/ The repair is easy to do if you can solder, We have 4 units in right now for repair. Check out your board, I would bet his is what your problem is.

I hope this helps, if so please rate our solution.
