building a new pc - no display, no beeps

Building a new pc using this motherboard: GA-MA785GMT-UD2H

and a 500W power supply (1 x 20 pin & 1 x 4 pin connectors).

The CPU fan, hard drive and power supply all spin up but no display on the monitor and no beeps.

Have tried: taking out all of the memory and still no beeps

used a different power supply and still no display

I only have the Motherboard, memory, CPU, heat sink & fan & power supply connected.

Any ideas?

Do I have a faulty motherboard?

Solution 1:

Things to check;

• Make sure all the power connectors are connected and secure
• If you can, try another monitor or a dedicated graphics card

The problem could be with CPU or motherboard. Did you use thermal paste when seating the heatsink?

Solution 2:

Did you add a motherboard speaker? GA-MA785GMT-UD2H doesn't come with a speaker so I added one from an older motherboard (it uses two of the pins in the same slot where the other connectors go for pwr, hdd_activity, rset) in order to get the beep codes - in my case a continuous series of long beeps :-(
