I had just removed dust from the fans on my Dell Optiplex GX260 desktop power supply and processor. I started the PC and it worked fine. I now replaced the the hard disk and suddenly an orange light appeared on the motherboard. Since then the PC has refused to start, and the orange light comes on whenever the system is connected to the power source. HELP!

Either the motherboard or power supply are bad. I've had both be the cause of the problem. Check the motherboard for bulging and discolored capacitors. The same can be true of the power supply.

To the guy above who said his were out of warranty. If the motherboard is the cause of the problem, Dell will replace it until near the end of January. Just call them up and try to convince them. We are an educational customer, but everyone should be able to get it. It's a known defect.

Did you check the Power Volts At the back of the system? you will find one red colored power switch 220/120. If its on 220, and you plugged in 110 power then you will get that light. Regards

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. Good luck

My Dell Optiplex gx260 Pentium 4 Flat CPU doesn't Display anything, and Power light is Orange.. Please help me out

You say the power light is orange--I'm assuming that you mean the monitor.
This indicates the monitor is not receiving a signal from the computer.
Assuming that the computer actually powers up (fan runs, you can hear the hard drive being accessed, etc) then your problem lies in the video card.

If, on startup, you do see the BIOS info and maybe even the Windows splash screen before your monitor goes dark, then the problem lies in the video card drivers. In this case, starting in safe mode will work and allow you to download and install new drivers.

Optiplex gx 260 steady amber light - done all things on dell website - still doesnt turn on. got a new PSU and it still has the same problem. theres a whirring sound which is the fan and the power supply...

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

Orange power switch light Dell Gx260

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.

Dell PC Desktop Optiplex GX260 Doesn't boot

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!

Orange Light permanently on motherboard. PC won't start

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..

2. I found this thread that may be helpful, it may be the motherboard may have gone bad, cmos is corrupted or something may not be seated could also be one of these: Bad CPU, BAD ram, Bad power supply.. read the thread for details:

Orange Light permanently on motherboard. PC won't start

If all you did was change hard drive
I suspect the hard drive has been installed wrong
Ensure blue or red stripe goes to the number 1 pin on M/board and the stripe goes next to the 4 pin power supply on hard drive

Optiplex GX260 won't boot

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!
