Dell Optiplex 980 Flashing Error Lights
My friend and I are attempting to take a school computer (Dell Optiplex 980), and using our HDD, GPU, and PSU, take it to a competition for video editing. All of our components work, but we're still getting a flashing 3 4 lights when turning it on. We've taken RAM from another Optiplex 980 that we know works, but still it doesn't work. We're thinking it's the motherboard, and have found a cheap one to replace it, but we were wondering if there is anything else we can try before buying it.
Thanks in advance for any help!

Lights 3&4 is shown as memory problem. But, since you have used memory from a working 980 and it still does not work, that points to likely motherboard problem. Because of the proprietary motherboard, connections, case, etc, anything other than another 980 likely will not fit or have the correct front panel connections.

blindseal,
The 3,4 diagnostic leds would mean the following issues. If you remove the memory from the computer do you get any beep codes? If not, the MB is possibly dead.

Maybe politely request the school for a working one, so you can complete your project. Maybe the instructor can help?
If you were in Texas, I would let you borrow a computer (or help you get a suitable one). :Smile:

That was our backup plan but our instructor had a few broken ones lying around and using those would be a lot easier than trying to go use the working school PC's as they care more about them. So now we use the backup plan :BigSmile:

What is your current error code, 1-2 or 2-3-4?
Try changing the size 2032 CMOS battery (on the motherboard) and How to Perform a BIOS or CMOS Reset and Clear the NVRAM on Dell Computers.
