DELL GX 520 Motherboard power led is orange, power button led is orange, the fun is running, no beep, no display....somebody help me with this dell gx520. sometimes it displays 3 and 4 lights on the front...

you should replace the motherboard or the power supply of your computer. to determine which one to replace is a simple test. disconnect all that is connected to the motherboard and if the problem is still there, then the problem is the motherboard.

Why would the on/off button be yellow-orange instead of green when the computer is turned on?

Solid yellow-The Dell Diagnostics is running a test, or a device on the system board may be faulty or incorrectly installed

Blinking yellow- A power supply or system board failure has occurred

THe pc gives a steady orange light when power

Sounds like its in either standby or hibernate. Try unplugging it if it wont power on, press the power button, wait for 2 minutes then plugging it back in then turn it on. Afterwards, go into power managment, and find where it asks what do when you press your power button change from hibernate/standby to ask what to do.

Unable to upgrade onboard graphics on dell gx520

Try disabling your onboard graphics in the BIOS. Some BIOS allow this. If you have a sound card, disable the onboard sound too. Count your beeps. they contain a code. Go online and "Google" bios codes. This should give you a starting point to diagnose the problem.

Hi guys, just been given a dell optiplex gx520 to tinker with. when i plug it in, the power switch on the front flashes orange and the unit doesn't switch on. any ideas??

Did you open the case up and do a general inspection. Things to look for:

Is the CPU installed correctly and tight?
Is the RAM installed correctly? Are they the right type?
Is there another PCI cards? If so, make sure they are inserted tightly.
Are the power cables for the mother board attached correctly.
Look at all the unused power connectors for drives. Make sure the metal part are not touching anything conductive.

Good luck.
