Intermittent CPU POST code

[Chokichi]

TL;DR: Ryzen 5 3600 won’t POST after restart from Windows 10. Just upgraded to X570s Aero G and 3070 Ti. 

 

Backstory: I had an ASUS X570-p and used the BIOS to overclock my 3600 to 4.2 Ghz. After overclocking the system would fail to POST after a restart from Windows 10, but hitting the power switch on the PSU would let me boot again. I just avoided restarting and completely shut down instead. Never had any problems with shutting down. I got selected in the Newegg Shuffle last week and bought a bundled Gigabyte 3070 Ti Eagle and the Gigabyte X570s Aero G. I installed both last night. Things worked fine after installing some initial updates, but when my computer tried to restart for a Windows update, it failed to POST and the CPU post light was solid. I hit the PSU switch, waited a few seconds, and turned it back on. The CPU POST code remained though. I tried unplugging all the usb and displays. I tried removing the RAM and only using 1 stick. I cleared the CMOS. I reseated the CPU. I put the CPU into my old MOBO with my old 2060 and it still didn’t post. After blowing what looked like dust out of the pins and putting it back into the new system it finally POSTed like nothing was wrong. I made the mistake of rebooting again to turn on XMP and I once again have the CPU POST code. I don’t know what fixed it before, but I’m afraid that the CPU is damaged in some really specific way that affects restarting only.

 

Please help…

 

System:

CPU: Ryzen 5 3600

GPU: 3070 Ti

RAM: 4 x 8 GB Patriot 3000 Mhz

Sound like a bad seating of the CPU. This can be bad.

Inspect your CPU pins before seating it in the 570. If you have bent pins, there's your problem. 

Once you reseat it, make sure you cooler put equal pressure on the socket.

Thanks for the response. This makes a ton of sense. The problems started when I upgraded my cooler from a hyper 212 to a NH-U12S. The CPU came out of the socket with the Hyper 212 and probably damaged the pins then. I almost never restart the computer so I didn’t notice until I tried to overclock and had to restart to BIOS several times.

Well I can’t find any visibly damaged pins, but after reseating it did boot and after restarting I got a RAM POST code, but I think it is some damage to the CPU. I’ve been wanting to upgrade anyway so I’ll try a new CPU.

Update: Bought a 5800X and it doesn’t work either. I think there’s something wrong with the power delivery to the CPU because neither of them is getting warm when booting. I tried a different cpu power cable and reseated the ATX power cable. At this point I’m thinking there’s something wrong with the motherboard.

If anyone stumbles upon this, I think there was a problem with my 3600 and the X570s motherboard. I returned the motherboard and stuck with my old one which was also an X570 just not as nice. I upgraded the CPU to a 5800x with the money from the MOBO RMA.
