PC Powers On, No Post, Please Help!

Howdy!

 

I've just put together a new tower, and cannot get the sucker to post. Spec below:

 

MOBO: ASUS AM4 TUF GAMING X570-Plus ATX

CPU: AMD Ryzen 9 3900X 

RAM: Corsair Vengeance LPX 32GB (2X16GB) DDR4 3200 (PC4-25600) C16 1.35V

SSD: addlink S70 512GB SSD NVMe PCIe 3x4 M.2 2280

GPU: Two Radeon R9 290X (Reused from previous build w/ bad mobo, could not independently confirm working)

PSU: Seasonic 850w (Reused from previous build)

Monitor: Monoprice Zero-G Gaming Monitor - 27 Inch, WQHD With AMD FreeSync, 2560x1440p@144Hz, 1ms, HDR, 400nits, TN

OS: Will eventually be Windows 10 Home 64 bit, but haven't gotten that far yet.

 

Everything powers up, green LED (for Boot), no post. I try both DIsplay Port and HDMI out of the monitor into the motherboard and both GPU slots, no luck.

I confirm all cables are plugged in.  My motherboard CPU power has an option for an additional 4-pin but my power supply only has an 8-pin.  Some internet research reveals that the extra 4-pin is only needed for overclocking.

I try every possible configuration of RAM, including a single in A2, no luck (this memory is new, so likely not the culprit.

Yes, the CPU has plenty of thermal paste and is seated correctly.

I try booting with no GPUs, in addition to the Green Boot error, I also get a white VGA error.

I try the GPUs one at a time in each slot, checking both mobo & GPU ports with HDMI & DP, just the green Boot error and still no post.

 

The only thing I can think is that BOTH of these GPUs, recycled from an old BTC miner, are bust.  That would be a real shame, so I'm hoping y'all can point out something I've missed.

 

Many thanks!

There are no integrated GPUs in the 3900X, so thus you will get a VGA error because there is no VGA. 

Do you have another graphics card laying around besides the two R9 290Xs? 

 

Is there anything on the SSD (addlink S70) or is it completely new?

It does sound like these are bad.

Are all the other components new other than these and the PSU?

This doesn seem like a power issue so i would suspect the video cards themselves.

And the onboard port wont work as mentioned above, no graphics in the CPU.

Sadly not, if I did I'd be using it.

 

SSD is brand new.

Thanks for the insight, y'all.  Looks like my concerns are validated and I'll have to get a new gpu.

I agree, good luck. Come back and let us know if that fixed it, if you think about it. 🙂

Hey, if you are using a modular PSU then try unplugging all the cables from the PSU and plug them back in afterwards.

Update: after further testing I determined that it was one, not both, of the gpus that had failed.  Computer is up and running now, though I've run into another issue that I'll post about shortly!
