Optiplex 330 power button is orange - Dell OptiPlex 330 Desktop Desktop Computer

Hi

The symptom you describe indicates a power issue, the most likely cause the PSU in the unit is failing, if you have a lot of USB devices connected try removing some of them, You could also try removeing all connected devices other than monitor keyboard and mouse and see if this will allow it to boot, but the most likely fix is going to be a new Power Supply unit.

change power supply (SMPS)

An Amber blinking power button indicates a low voltage problem. This can be caused by a defective power supply or a defective motherboard. Since you replaced the power supply, my guess is that the motherboard has a problem.
Just to make sure that nothing else is causing the problem, remove any PCI cards like modem, video card, sound card, etc... Remove the memory modules and disconnect cables to CD/DVD drives. Look at the USB ports to see if any are damaged.

replace the power supply

Flashing Amber, bad power supply

Solid Amber either a bad component connected to motherboard of the motherboard itself has failed

Try to clean the RAM and place it again in the motherboard.

If you are getting no video at all, then we can use the diagnostic LEDs and the power LED to help determine the failure.

Solid Orange/Amber generally is a Motherboard failure. Remove all expansion cards and all external connections, see if anything changes. If not, replace motherboard. If you get a change, then add items back one at a time till you ID the Fault

Please try the following and let me know

Turn off the system
Disconnect power cables
Press and hold the power button for 30 seconds
Reconnect power cables and try to turn it on.

Let me know if you get any beep sound

get a new power plug

Do you have a lot of accessories plugged in? You may have overloaded the power supply, and if that happened then you will need to buy more powerful power supplies. If that's not the problem, they systems may have overheated if they don't have enough ventilation in the back.
