System won't boot

Penf0ld · 17 Feb 2020 at 13:51

Hello, I recently purchased a new ASUS B450 Gaming Pro motherboard. When I turn the system on the board receives power and the fans spin up but all I get is a black screen, no beeps or anything.

This board has 8 pin connectors for the CPU and my PSU only has 4 pins so I'm wondering if this is the problem? I've seen elsewhere that some people are fine with just connecting 4 pins...can someone confirm if this would be the case for my particular board or if they've had similar problems?

Thanks will see try a new PSU and see what happens. I was trying to build on a budget hence the 1600x CPU and one stick of RAM (idea was to buy another stick in future.)

Tried RAM in slots A2 and B2 so far, GPU in both PCI slots.

Yep GPU is connected with power to it and to monitor as well.

Unfortunatley no spares to play with so might have to bite the bullet with a new PSU and hope that works...

New PSU has arrived today so going to give that a try later tonight, the local PC store said they would charge £20 for diags

Sadly not

, just wish I had a few more spare parts to swap around

Tried clearing the cmos, left it on for a while for memory training as mentioned by Steven but still no luck.

Don't think I'm going to be able to flash the bios in it's current state (black screen is all I'm getting). Thinking of now taking this down to the local PC shop over the weekend so they can find out which component is causing the issue.

I only have one stick of ram

, I could buy another but if it's not that then it's either the CPU or board.

I have a Ryzen 5 1600x, the product specs said it would support 1st gen Ryzen so I assumed it would be ok out of the box.

No RAM? not tried that yet, the board does power up but I'm not seeing any video ouput. What would happen if I tried with no RAM?

I'm not sure my case has a speaker, will take a look later this evening

It stays on, I've got an LG monitor can't remember the exact make / model but I've tried all inputs

Penf0ld · 19 Feb 2020 at 16:59

actually I've managed to borrow a GPU from a friend, it's a great big hulking ATI of some sort can't seem to find the model of it on any of the stickers...

I'm thinking it may be the RAM, just looking at the QVL and the stuff I've got isn't listed on it but then I guess they can't test every single vendor and model

Penf0ld · 19 Feb 2020 at 19:43

Monitor and cable are fine as I used them on my last PC (Intel build), just swapped out the loaner GPU and still nothing, took the RAM out as suggested but no beeps.

The problem is I’ve no case speaker as I’ve checked and can’t see it so I’m troubleshooting blind.

Just to let you guys know I finally managed to get this working. I took the board outside of the case and only then could I see that the RAM wasn't sitting flush. On this board there is only only one clip / lever to push the RAM in so the other side wasn't all the way down.
