Help! New PC wont work!

[OldFord76]

I just finished building my first computer ever, literally an hour ago. I pugged in the monitor to the motherboard, turned them both on, and no signal.( I'm using on-board graphics, I don't have a gpu, so that's why I connected to the mobo) I've tied everything I can think of but nothing happens. The fans just spin and the monitor stays blank. I connected the monitor to my laptop with the same HDMI cable, both work fine. But nothing will connect. I've tried connecting keyboard and hitting delete but nope. What should I do? I don't have a disk drive, do I need to install drivers or something? I hope to God its not broken. Please help!

What CPU do you use?

[Acuitio]

I had this too when I finished building mine it’s expected if you don’t have windows installed yet

@Acuitio no it is not. You should ALWAYS get into your BIOS no matter if or what OS you have installed.

Are you using a CPU that has integrated graphics? Just because the motherboard has display outputs doesn't guarantee that all CPUs will support them.

[Pixelfie]

What cpu? Not all cpu's have integrated graphics (for examples Intel's ending with F and most Ryzen 5's). Also, if your mobo has a light indicating what's wrong, maybe that can help?

Its the Athlon 300g from AMD. The motherboard does support integrated graphics, according to the manufacturer and several other websites.

No, the keyboard and mouse were unresponsive.

Did the computer POST properly? (keyboard, mouse, all light up). When you hit the num-lock key, does it function? (light on and off)

 

If you hear the fan spinning, keyboard is functioning properly, mouse is lit up, and num-lock functions properly. Then everything is fine. The problem will just be your HDMI cable. Most start-up PC does NOT support HDMI without first installing the driver and this doesn't happen until you finally log onto Windows. Instead of HDMI, use DVI cable (if your monitor supports it.) Then restart your PC, and you should have visual.

no, nothing happens. The case RGB comes on and the fans spin and that is it. Nothing on the keyboard, mouse or monitor. Any ideas whats wrong?

Visual is fine. Improper connection. You need to do a checklist that you installed and connected everything properly and is in the correct port.

 

Checklist for POST

I have, everything is in place. I talked to a friend who is a tech specialist and he says everything looks like it is connected fine. Thanks for the help, but im not sure what to do at this point.
