Custom Built PC beeps three times and won't show hdmi output

[YuriyTheGamer]

I built a custom gaming PC yesterday but when I turn it on, it beeps three times. At the same time, my monitor doesn't display nor detect my PC. The fans are working and the graphics card lights up. What could be the problem? Btw, it's an AMD build. Thank you.

It looks like a memory issue. Try testing with single RAM module each slot. Make sure that the module is properly inserted (both latches in closed position).
If still 3 long beeps, then try borrowing a RAM module and testing.

I just tried that. Still no luck. Could it be that the ram modules are broken because when the package arrived, I could easily open the package without any tools? The package was slightly open when they first arrived. Could that be the problem?

Hard to believe that both RAMs are defective. But not impossible.
Can you borrow a RAM module from a friend?

I just got a replacement package from Amazon for the memory modules. I'll check each slot and update you.

 

[alexoiu]

ok.

 

[YuriyTheGamer]

ok.

Everything seems to work now. I'm just a first time PC builder so I don't how things work. The ram modules weren't properly sealed in the slots. It's supposed to click in twice not once. I thought it had to click in once from one side but I was wrong. Everything works now. Thank you.

No problem.
