Just booted newly built computer for the first time and nothing shows up on the screen. Help!

So I've just finished my first build and powered it up. All the fans appear to be spinning, some LEDs come on but my monitor doesn't recognise that it is connected to anything.

By build was:

  • Corsair TX 650W PSU
  • ASROCK 870 extreme3 mobo
  • G.Skill 4GB RAM (2x2GB)
  • Samsung F3 1TB HD
  • Antec 300 case
  • GTX 460 1GB GPU
  • AMD Phenom II Processor

I know the monitor works fine, so do you have any ideas or help for this problem? Thanks Reddit =)

Thanks Reddit - it appears one of my sticks of RAM is faulty .

Are your 8 pin CPU (up and to the left of the CPU) and PCI-e (on the rear of your video card) cables connected?

I think so. Just to check, from the power supply I have connected an 8-pin and a 24-pin to the mobo, and then 2 PCI-e cables from to the GPU from the power.

Those are usually the most looked over problems. It could be RAM, try reseating and making sure it clicking in all the way, then trying one stick at a time. If you have your motherboard speaker hooked up it should be giving you some sort of beeping error code.

You sir are a God amongst men.

I removed one stick of RAM and it has gone into the BIOS. Does this mean one of the sticks is faulty? I've tried reseating it but the original problem reoccurs.

Check Page 15 of the manual...you need your ram in the right hand sockets.

That is correct. You have lights and the fan is spinning...so power is good to the MB

Have you tried both video connectors?

Is there a system speaker - did it beep?

Both video connectors yield the same result, and unfortunately I don't think there is a system speaker.

Take both sides off the case and check each screw thru the motherboard engages with a post and you have no extra posts and no extra holes!

Meantime if you could cannibalise a speaker from somewhere it would help you a lot.

What brand GPU? Do you have access to another PC to test the video card?

2
ChumpesqueOP•

It's a Gigabyte. No other PC close to hand at the moment I'm afraid.

Have you tried all the ports on the video card? If you don't have another pc to test the video card or video card to test the system, you're at a standstill.
