Orange Light permanently on motherboard. PC won't start
I cleaned the fans of my Dell Optiplex GX260 desktop PC's fan and power supply unit. Thereafter I turned the PC on and it worked fine. I then replaced the hard disk and the PC didn't start again. When I checked inside, I observed an orange light on the motherboard. It stays permanently on but the PC won't start. HELP!

Re: Orange Light permanently on motherboard. PC won't...
1. motherboards for atx form factor pc's are powered even when the computer is off, particularly if you leave the computer plugged in to wall outlet... you better do not work on you computer while power cable is still connected to both, your pc and the wall outlet..

Steady Amber Power LED generally indicative of a failed MB. Remove all Memory, Expansion Cards, peripheral items, if still same, replace the motherboard. If you get a Green LED with jusr RAM in system, then an expansion card or peripheral might be the issue. 95% sure it is mothebroard
Gx260-Gx280 have a known issue with the motherboard capaciators. Take a look at the capaciators on the motherboard and check if any look like they have bludges at the top particularly around the memory banks. If any of them look like this the motherboard most likely needs to be replaced.
Open up the case and remove any add in cards and memory modules. Try to start up by adding these back one at a time until the unit stops booting normally. The light combination is not one recognised in the user manual so I am guessing you have a non-descript fault with one of your components. Be careful when you open the case as to not disturb the ribbon to the motherboard which controls the power, I have had a very long experience trying to get one of these reconnected!
I had the same issue and accidentally discovered a temporary solution. Unplug the power from the back of the machine, open the case and unplug the ATX power connection from the motherboard. With the ATX cable unplugged, plug the power cord back in. When you try to turn the computer back on the power light should turn orange and fans should be spinning, with it powered on plug the ATX connector back in. That should turn the computer off. Turn it back on and it should boot fine. You can even shutdown and restart, but when the power is unplugged you will have to go thru the same process to get it back up. This sounds crazy but it worked on mine. Good Luck!
Have you checked the post lights located in the back of the system by where the keyboard plugs in?
There are is a row of 4 lights; either yellow or green. If the systems gets stuck at a particular post location, the lights will tell where.
