Dell Optiplex SX280 Tags: Dell Optiplex Computer Computers Last response: October 9, 2011 1:54 AM in Computer Brands Share emlo68 October 8, 2011 12:51:14 PM Hi all, I have a Dell Optiplex SX280 and having loads of problems with it. It started when the computer fan would kick in really loudly and then the computer would automatically shut down. Now I can't even turn it on. When I press the ON button the power light flashes orange but it doesn't go beyond that point - the screen remains blank. Any help would be greatly appreciated. Many thanks in advance.

Ubrales October 9, 2011 1:54:17 AM Mine (Optiplex GX 745) will do that if there is an external storage device connected to the front USB port. When I start the computer, I make sure that there is nothing plugged into the front USB port. Can't find your answer ? Ask !
