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.

Hello,

The Optiplex 745 units have been having a good deal of problems related to failure of parts called capacitors on the motherboard. We have a repair guide posted at: http://www.ccl-la.com/blog/index.php/dell-optiplex-745-repair/ that explains the issue and what to look for. The board can be repaired for less than $15.00 if you can do a little soldering. Check your board and see, my bet is you have the bad caps.
