New PC Will Not Post

Hello Linus Tech Tip friends,

 

I'm having an extremely frustrating issue. I have made my own PC in the past and never had a problem like this before.

 

First off I'm currently running a Asus ROG Strix B55O-F Mother Board with a Rhyzen 5. The computer will turn on and all lights including motherboard, GPU light up and run as well as all fans are spinning. The PC seems to be running completely fine except that it will not post.

 

I tried forever by trial and error to see if any part was not inserted all the way and had no luck. Then I got so fed up with it that I brought the computer to the local computer repair shop and had the guy try to figure out the problem. He told me that all of my parts worked in his computer and he can verify that they aren't the issue. He recommended that I get a different motherboard and that it was an extremely rare issue that the motherboard at the time (a new Gigabyte motherboard) was incompatible with my video card and that I should get a different one. I have since returned the old one and bought two completely different motherboards (one an MSI and the latest being the Asus I mentioned in the beginning). Neither of these motherboards worked and the problem persists.

 

 It might be worth mentioning that the monitor I am using also is working just fine with my laptop.

 

Help would be much appreciated. Please let me know what else may better help narrow the problem down.

 

Parts in computer:

CPU: Rhyzen 5 3600

Motherboard: ASUS ROG Strix B550-F Gaming

RAM: Crucial Ballistix 3200 MHz DDR4

GPU: Sapphire Pulse 5700 XT

HD: Intel SSD

I dont want to sound rude, but do you have the monitor plugged into the GPU or maybe the HDMI or DP in the motherboard? The R5 3600 doesnt have an internal GPU, so it wouldnt even tell you to plug your monitor into the GPU, as Intel does in some occasions.

 

It should not be possible that a motherboard is not compatible with the graphics card.

Not rude at all. I know you're just eliminating possible problems. Unfortunately I did plug the monitor in the GPU so it is probably not that problem.

tl;dr: obvious milking is obvious.

 

It might be dumb and useless, but try to reset CMOS on the motherboard itself.

more easy issues, are you sure your GPU power cables are plugged in properly, and the 8pin CPU cables are plugged in to the motherboard?

does that motherboard have debug LEDs?

We can't Benchmark like we used to, but we have our ways. One trick is to shove more GPUs in your computer. Like the time I needed to NV-Link, because I needed a higher HeavenBench score, so I did an SLI, which is what they called NV-Link back in the day. So, I decided to put two GPUs in my computer, which was the style at the time. Now, to add another GPU to your computer, costs a new PSU. Now in those days PSUs said OCZ on them, "Gimme 750W OCZs for an SLI" you'd say. Now where were we? Oh yeah, the important thing was that I had two GPUs in my rig, which was the style at the time! They didn't have RGB PSUs at the time, because of the war. The only thing you could get was those big green ones.

Glad I refused further help from him.

 

I can confirm that after CMOS reset I have no changes.

Do yo have a way of testin the cable with a different monitor?

 

Also, i always have some problems if in want to go from HDMI or DVI on the GPU to DP on the motherboard. The best thing is to always use a 1:1 cable, meaning the same connection on both ends. Try a different monitor cable and of course, make sure that the monitor is set to the right input.

To the best of my knowledge they are plugged in properly and unfortunately my motherboard does not have debug LEDs.

I just tested it with a different monitor and I had the same result. Also I am using an HDMI to HDMI cable. Both monitors are confirmed to be set to the direct input.

Shouldnt the GPU display that there is no PCI power plugged in? I had that on my old GTX660, and it displayed the text, that the GPU needs additional power.

some may, some my not. 

I have a gtx560TI that will, but a gtx1070 that won't, and i'm not sure about my rtx2070S

I can confirm that the GPUs letters are lit with bright red LEDs when the PC turns on.

Do you have a different powersupply you can try?

 

And check if the Num LED lights upp and shuts off when you press it. If it doesnt, then the system did not post.

 

 

Unfortunately I don't have another one. The Num LED show up but then change to AA.
