Dell Optiplex 760 Diagnostic Lights Flashing
Hello, I seem to be having a problem with my Dell Optiplex 760. I have tried unplugging and replugging all of the connectors from the motherboard and I have also tried removing and reinserting the RAM. However, the problem is still apparent. When I plug the computer to a power source (have tried UPS, surge protector, and directly to a wall outlet) and press the power button, the power button flashes amber and the numbers 1 and 3 flash in green on the front of the computer. Does anybody know what's going on or have any suggestions? Thank you.

Manual (page 162) doesn't say anything about the LEDs flashing, but a blinking amber power button with LEDs 1&3:
A possible motherboard, powersupply, or peripheral failure has occurred.

Hello UsvartJ,
Ron has provided an awesome step by step troubleshooting for testing the power supply and motherboard. If you need a video, here is youtube link that walks you through the process: http://en.community.dell.com/support-forums/desktop/f/3514/p/19534032/20480041.aspx#20480041
Please let us know if you run into any difficulty.

We are having problems with about 4 760s, SFF. Blinking Amber power button, LED's 1&3 are blinking as well. Have replaced psu, checked with known good front panel, etc. I don't see a link to the youtube video, but we are starting to have lots of problems with these.

I pinged my Dell tech contacts and they're going to look into this problem.
Stay tuned...

Hi,
I had the same problem with 2 PC's. Blinking Amber Light (Start Button) & 1,3 Green Lights.
I solved the problem by replacing the SMPS.
