So far I have always been able to boot eventually, but it can take multiple power cycles and re-seating the GPU or completely powering off and disconnecting the PSU power before I can get a successful boot. Sometimes I get a nice, fast, normal boot, but mostly it's the above issues. I feel like the issue is likely the motherboard, but it is out of warranty and I'm trying to avoid replacing it if possible.
Here's a video of 4 total cycles until a successful boot showing boot codes:
I also get distorted boot screens from time to time right before the windows login. The POST screens are not distorted prior to the Windows loading screen. I've experienced this with both GPUs tested.
I doubt that there's anything I can do on my end to fix this, but I am hopeful. If nothing can be done I am considering an out of warranty repair, but I have no idea of what that might end up costing or if its possible.
My RAM was already set to defaults with XMP disabled, I did try manually setting my ram to 15-15-15-35 @ 2666MHz 1.2V, but the issues have persisted.
I'm going to completely take apart my PC and reassemble it while checking for any possible damage in each component. Will also inspect the CPU socket and make sure to evenly attach the cooling block from my H115i AIO. If the issues still persist I'll switch to the 2nd BIOS chip and see if that makes a change.

Completely disassembled and reassembled my PC, checked the CPU socket and CPU for anything odd. Nothing there. Applied new thermal paste and reattached CPU cooler making sure every screw was tightened evenly. First boot with 2nd BIOS chip had multiple power cycles with the new and old BIOS so no change there [Both at defaults]. I think the motherboard is on its last legs, getting harder and harder to get a successful boot.
I'm open to any other suggestions, but I'm interested if anyone has any idea if I can get an out of warranty repair, and if so what the cost might be. Since it's not the BIOS chips and all PCI Express slots seem affected, I don't think a "repair" can be made.

Hi, I did a clean install due to some boot issues and then performed some startup testing:
10 Boots with RAM at 1.20V default resulted in 2/10 boots taking 4 power cycles to boot
10 Boots with RAM at 1.35V default resulted in 1/10 boots taking 4 power cycles to boot
When I initially reassembled my PC it took 9 or 10 attempts (Stuck on GPU not detected and had to fully shutdown), but since the clean install I think I've booted around 30 times this weekend including the above tests and now it seems a lot more stable. Nothing seems conclusive about the RAM voltage unless I were to do a lot more tests. I really just want to know what the actual issue is.
Since the clean install I've only had the issue of taking 4 power cycles to boot, none of the other issues have presented themselves (yet). I'm hoping that it might just be a stability issue and not a hardware degradation issue.
Had only the occasional 4 power cycle boot since my clean install till today. Got another display artifact screen at the windows login which then prompted my PC to reboot into Windows diagnostic mode where the repair said my pc could not be fixed and shutdown. Had to reboot about 4 times with GPU not detected beep codes till I could get back. Ran sfc /scannow and there were corrupted files! I have booted my computer with no drives attached at all and still got the same issues so my 850 EVO can't be the cause of my main issues (I woudn't think).
Also, I found some residue near my first PCI Express slot, not sure what it is. It's mainly on and below the Asus ROG chip (ID'd as just "ROG" in the manual) that sits between the first 2 PCI Express slots and directly to the top-left of the chipset heatsink. The picture kind of makes it look like the ROG chip has burst, but It is just more residue. Solder flux?
