[SOLVED] Yet another "won't post" question

Sorry ya'll, I'm sure you guys see a million of these posts everyday. I've done a lot of research, but I'm still not completely clear on how to proceed, so if you could help me out that would be great.

I've looked over and read this thread too:
http://www.tomshardware.com/forum/261145-31-perform-steps-posting-post-boot-video-problems

I had to scavenge parts from my existing one PC at home to do this build, so I don't have a working computer at home I can use to help me troubleshoot, so I'd like to come up with a tight, concise plan of action to make this work while I'm at the office that I can execute at home instead of having to look up solutions on my phone.

Here are my parts:
* Mobo: ASUS ROG B350-F GAMING
* CPU: Ryzen 5 1600X + Arctic Freezer CPU Heatsink/Fan (comes w/ thermal compound applied)
* RAM: 2x Kingston HyperX Fury 16GB 2666 MHz DDR4 - 32 GB total (HX426C16FBK2)
* SSD: Samsung 860 EVO 500GB
* PSU: EVGA 650 GQ
* GPU: MSI GeForce GTX 1060 *scavenged from current computer
* Case: Rosewill Rise

The mobo lights up, but I can't get anything else to run. No fans, nothing.

Here's what I've done so far:
* I tried shorting the power pins on the mobo but that wouldn't start it either.
* I double checked all my connections to make sure they're in snug.
* I wore an anti-static wrist band most of the build (forgot a couple times, but I worked in a very non-static environment and in my undies so I doubt static was an issue).
* All the proper standoffs came already installed w/ the case and I used every single one, so I don't think there's any risk of having standoffs touching the mobo at the wrong points.
* Checked to make sure RAM is installed in the proper recommended slots. Have not tried removing one stick though to see if that fixes anything.

Based on my research, here is a list of potential issues as far as I can tell. Let me know if you guys think one of these is the most likely culprit, or if its something else. I've done these in what I believe is most probable to least probable.
* Incompatible RAM - the RAM I got (HX426C16FBK2) shows up on the QVL for my mobo, but only on their Raven Ridge Ryzen QVL. It does not show up on their generic QVL. My CPU is a Summit Ridge Ryzen. With that said, Kingston's website says my RAM should definitely be compatible with my build, as did pcpartspicker. Don't know who to believe.
* My PSU is bad - I don't have a spare PSU to test though, as my current computer was a pre-built HP and the PSU appears to be caged into the chassis.
* MOBO BIOS issue - Read a lot of stuff online about a lot of B350 boards (including mine specifically) having issues w/ newer Ryzen chips due to needing a newer updated BIOS to POST, which causes a catch 22 since you can't update the BIOS without posting? With that said, most of those issues seem to have happened middle of last year, AND I believe my Ryzen 5 1600x is not one of the chips that had that issue anyways?
* Damaged GPU - When I installed my GPU into my old computer, the HP case was super small and I had to jam it in really hard to get it in. Worked fine after that, but I had an equally hard time removing it as well. Since Ryzen 5 1600x has no integrated graphics, I assume if my GPU was damaged during the rough removal from my previous computer, maybe it might cause some issues with posting? There are a bunch of superficial scratches on the graphics card, and I did have to use a significant amount of force to remove it from the old case, but I really don't think I damaged anything important though. Didn't hear any cracking or anything like that. It worked fine before despite undergoing similar difficulties during the original installation.
* Damaged CPU - Installing the CPU cooler was difficult. Had a lot of trouble latching the heatsink onto the mobo. At some points I was concerned I was pressing too hard on the heatsink and CPU to try to latch the mechanism.
* Short somewhere - maybe I dropped a screw somewhere or something and its causing a short? I really doubt it though, I was very thorough and careful every step of the way, and did not unpackage any screws or parts that I didn't end up using.
* Dead MOBO - really hoping its not this.
* Didn't wait long enough - I read somewhere on here that AMD builds can take up to 5 minutes to post the first time? Seems unlikely this is the problem, but I guess worth a shot to wait.

When I get home, I'm gonna remove the mobo from the case to check for shorts, try using one of my spare PSU power connectors OR try to somehow make my other computer PSU reach, and wait 5 minutes for the system to POST. After that, I am not really sure how to proceed to resolve this issue...
 
Solution
OK so I got the replacement CPU on Friday, realized I ran out of thermal paste so ordered that too, got that in on Monday, finally found time to work on this again tonight. Re-hooked everything up. Plugged it into my living room TV since that's where I was doing the build, and turns out that TV just died (shows a Toshiba splash screen but then none of the controls work) so I had to move everything back upstairs to my room and plug it into my monitors there. and its FINALLY up and running,. The build from hell is finally over.

Still have a few other issues though:
  1. system only identifies 16gb of RAM although I have 2 sticks of 16gb installed in the correct slots.
  2. i get massive amounts of background static on my Rokit RP5...
Based on this test, I assume if it works, PSU is probably okay, if it doesn't, PSU is probably the issue?

Do you know if there's any way I can test to see if the RAM compatibility is the problem, without buying, installing, testing, and returning more sticks?
 
OK so I removed everything from the case. Tested it with just the PSU, motherboard, CPU, and CPU fan (no RAM at all, no GPU, etc.) and same deal. LED lights on the mobo but no fans or anything running. When I short the pins, still nothing either.

I tested the PSU by plugging it into a different computer and it powered up and all fans spun (didn't have any outlets left for a monitor so I didn't see if it actually posted). I tested the CPU fan by plugging it into that different computer's mobo and it spun on just fine. I also removed the CPU and checked it again to make sure there were no bent pins and that it was seated correctly and it looks like it was.

So I guess this means I definitely have a bad mobo right?

ALSO again I'm still worried that even if my mobo is bad and I replace it, will I have any compatibility issues after that w/ my RAM? The RAM I have (HX426C16FBK2/32) does not show up on the mobo compatibility list for my (Summit Ridge Ryzen) CPU, nor on mobo compatibility lists for any of the other similar mobos I was looking at as a replacement. It only shows up on Raven and Pinnacle Ridge Ryzen CPU compatibility lists. However the RAM manufacturer's site (Kingston) says it should be generically compatible with any Ryzen CPU + mobo combo. And pcpartspicker says it should all be compatible as well... should I return the RAM I have now and preemptively swap it with something else?

Oh and just to make 100% sure I'm not making a dumb mistake, the pins to turn on the power that I should be shorting on my board should be the 3rd and 4th column top row pins, right?
 
ryzen 1 and 2 have same memory controller, summit ridge QVL is old, nobody will update it, that QVL is valid for first bios revision, later bios version (agesa updates) made plenty of other ram kits compatible

do u have hooked up speaker to mobo?

anyway, pull out your CPU, see if your fan will spin
 


Yes, those pins.
I would RMA both board and CPU firstly and then decide about RAMs.
 
I don't have a speaker to help me diagnose. Should I buy one? I don't think they're too expensive right?

Which fan am I testing for with the CPU removed - the CPU fan I assume? Can't test the PSU fan because the one I bought has eco mode so it doesn't turn on until it is under load.

Thanks for the help!
 
Any updates on this? Even RAM that is incompatible should still allow system to power up, just not POST. The memory controller was improved for 2000 series pinnacle ridge Ryzen as well as improved compatibility with kits. Getting no power up/startup at all from a system is usually power supply, wiring connection, or motherboard itself.
 
OK so I got the motherboard replaced by Amazon. Still the same problem - motherboard lights up, but CPU fan doesn't turn on even when I short the power switch pins, system doesn't POST.... I tried this test without any RAM, GPU, etc. connected, also with 1 stick of RAM connected, AND with 1 stick of RAM + GPU connected.

So I guess by process of elimination the issue is the CPU?.... I hope Amazon will switch it out for me too... I'm not a serial return-er but I feel kinda bad using their return policy as a trial and error system.

Any advice? Am I correct in my assessment to think the only remaining potential issue is the CPU?

I checked the PSU by plugging it into an older build (though that one only had 4 pins for the CPU power, not the 8 pins for my current build so I tested both sets of 4 pins) and all the fans turned on. Didn't check to see if the system actually posted by connecting up a monitor, since I ran out of outlets testing multiple different computers at the same time, but seeing as all the fans turned on, which is further than my current build got, I assume its unlikely to be the problem?

RAM compatibility is probably not a problem - it shouldn't affect the CPU fan not turning on. CPU fan isn't the problem since I tested it on a different computer and it ran fine. The new motherboard is highly unlikely to be the problem, since this would be the second defective in a row then. BIOS shouldn't be a problem since my Ryzen 5 1600+ should be fully supported even with non-updated boards. There shouldn't be a short in the case, since this time with the new motherboard I kept it outside the case the whole time...

I guess I could get a speaker like someone earlier suggested just to see if it points to any other potential problems, but otherwise I'm going to try to swap out my CPU?

Solution
OK so RAM wasn't pushed in all the way. Dumb mistake. Static in my speakers ended up resolving itself on its own somehow. So we all good now. Although my brand new (less than 6 month) corsair mouse left click stopped working now. Hopefully I can dig up the receipt and its under warranty... This computer build must be possessed. So many things died or went wrong.

How do I mark this issue as "Solved"?
