Hard to say what the code means without some specs and without a description of the length of the beeps. See the link below.


Likely is a problem with your graphics card. If you have no video when you first start the computer then try re-seating the graphics card with the computer unplugged.

"Processor runs continuously but no display"

I'm fairly sure the processor IS working because if it wasn't, there would be no beep codes. But I'm curious how you came to the conclusion that it "runs continuously"? Just because the CPU cooling fan is working?

Anyhow, you didn't list the make/model of your motherboard or which BIOS it uses (AMI, AWARD, Phoenix, etc). Each BIOS manufacturer uses different beep codes. I'm going to take a stab at it & guess that you have an AMI BIOS. 3 beeps = memory error.

Hi Riider......

I am using ASUS M5A97 (Auto O.C. Tuning & Mouse-controlled UEFI BIOS on AM3+ Platform) Mother Board.

Do you have on board graphics you can try instead of the card or another card to test out? Sounds like the video card, 3 beeps is usually ram or the graphics card depending on the bios maker.

Is this a new build? Post detailed hardware specs for CPU, RAM, power supply model, etc.

I have no experience with UEFI type BIOS settings.

If you are not seeing anything at start up then you have some sort of hardware issue.

My guess is you're not fully seating the RAM in it's slot.
