I have a Dell Optiplex GX260That was given to me, When i turn it on the push on/off button turns amber and the little light below it is green. I get no picture on screen, the motherboard has a light beside the power supply that is amber... I tryed the 4 lights on the back thing and i odnt know if im doing it right or not, but nothing lights up. What i am doing is just pressing the on/off button and looking for the lights but nthing happens. The fan is turning on. The boy that had it before me took the processer out but he put it back in... Please help.....

Here is the service manual:
Note that there is no mention of the diagnostic lights. The big issue here is the removal of the processor. It is not a good idea to remove it unless the person really knows what they are doing. A lot can go wrong. If I were you, I would check the processor to make sure that there are no bent pins and it is inserted correctly. The grease they use on those to transfer heat is important. If it is not put back on or is not correct, then the processor can overheat. Another basic thing you can try is remove all the things attached to it, take out the ram etc. Leave the monitor connected though and see if it boots up with nothing attached, including the drives. If it does then you start putting things back one at a time to see if you can isolate what the problem device is.

SOURCE: Workstation POST

POST measn power on self test. It happens as soon as you switch the system on and the CPU runs the BIOS POST code. During POST the screen is initialised and then you may see some text and messages. Before the screen is initialised, the speaker may beep with error codes to tell you that something is wrong. e.g. two long - one short beep. Different sounds  means different things.
Do you have a specific problem?

Start button flashing

It depends on the color, if it's green or amber. This may indicate the computer is in sleep mode. Press the power button to see if you can turn on the pc. If it doesn't press and hold power button for five seconds. You may give more details. I hope this helps

Power light not turning green just amber.not a power flactuation problem

There are a few things you will have to do. First, remove any newly installed card in the PCI socket if any. Try to re-sit the memory chip modules, that's removing and re-installing them. If they are two, try replacing one after another. Thirdly, try another VGA card incase you using the onboard one. Finally, swap your monitor. It must work. Good luck

Dell Optiplex Power-on Problem

An Amber or Yellow power button means that the power supply is receiving power from the source but is unable to properly distribute it to the components. This can be caused by a defective power supply or a defective motherboard. Just to make sure that nothing else is causing the problem, remove any PCI cards like modem, video card, sound card, etc...
Look at the USB ports to see if any are damaged.
