It seems like a RAM problem. Originally it was 18 GB of DDR4, now it's 14 GB? That suggests you mixed the RAM types. Your issue stems from mixing and matching. It doesn't function properly. Please choose a single kit. If you plan to add more RAM later, purchase the complete set you need. Avoid simply adding RAM without proper setup.
I concur this is likely the cause. Even with 4 stick kits, the voltage to the memory controller might need a slight adjustment.
Yes, I believe it could be related to RAM as well—it's similar when power is lost, though it might work if the RAM speed and brand match.
It may be a dual-channel configuration; in that case, you should detach the "pair" from the dead RAM chip to resolve the issue.
I thought you were mixing RAM because your numbers changed—from 18 GB to 14, then to 12. That doesn't add up.

sounds like a ram issue. (originally) 18 GB of ddr4, now it's 14GB? Which means you mixed and matched the RAM. Your problem is the mixing and matching. It doesn't work. Drop down to your bigger kit. Just one kit. If you want more RAM in the future, buy the full set you need. Don't just add RAM to your system.
I agree this is most likely the problem. Sometimes even with 4 stick kits, the voltage to the memory controller needs a slight increase.
Yes, I think it could be RAM too—it's similar when power is cut, though it might resolve if you wait a while. I plan to test it tomorrow with just one stick. By the way, where should I adjust the voltage for the memory controller and how much? Is it different from RAM voltage?
My friend says there used to be no issues if the RAM is the same speed and brand, but you might still have problems.
It could be a dual-channel setup; you'll need to detach the "pair" from the faulty RAM chip to fix it.
I assumed you were mixing RAM because you mentioned the numbers changed—18 GB to 14, then to 12. That doesn't make sense.
Aha, sorry m8, I mixed the figures. I'll try again tomorrow, thanks.
I've already booted the computer with just one RAM stick. It starts, crashes, and restarts once. I'm unsure what's wrong. The first failure was code B6 (NVRAM clean-up). Maybe it starts for about 2 seconds on BIOS, then shows 0 and restarts normally.
It's odd. If I turn the power back on to the PSU and try to boot, it works with one stick but fails again with zero code.

a 650W psu should suffice for a r9-280x and an i7, unless it's failing.
Regarding the RAM, let me explain further.
What motherboard are you using? That’s important.
Thanks for the advice. I mentioned this earlier—it’s a Gigabyte GA-Z170X-UD3 / Z170. Now it stops working after code 19 during pre-memory South bridge initialization.
It might be due to a BIOS update, but it seems it started without the GPU every time. I can hear some faint beeps or buzzing from the PSU, possibly indicating it’s failing.
Boost the vcore power. I encountered the same problem during my previous build. It was a Sandy Bridge i7 with a large motherboard. Whenever I powered it up from sleep, it would repeat this issue. Initially, it wasn't getting enough voltage, at least that was what happened. Make sure you're using only three RAM sticks and that the three closest slots to the CPU are filled. Also, remove all the RAM. Get a quad kit with all four sticks in one package. Personally, I prefer dual kits, but they're identical. I got them from the same store at the same time without any problems.
Ensure your boot drive is connected to port 0 on your motherboard; the PSU might also be problematic. If it's making noise, my approach is to invest in essential parts like the PSU, which people often overlook. The PSU is crucial. Whenever you skip two or more generations, replace it as well. This is my standard. With a PSU from 2015-2016 you might manage skipping three generations, but newer models are so affordable that it's surprising. You can find a Corsair semi-modular 750W power supply for around $89 at Best Buy, possibly even cheaper now.
JustEthan reminds to connect your boot drive to port 0 on the motherboard, as the PSU might be the problem too. If it's making noise, he advises prioritizing essential parts like the PSU, which many people overlook. The PSU is crucial; always replace it if you skip two or more generations. He notes that newer PSUs from 2015-2016 might work without them, but older ones should be updated. He also mentions finding a Corsair semi-modular 750w PAU for around $89 at Best Buy, possibly cheaper now.
JustEthan suggested boosting the vcore, mentioning a previous issue with his Sandy Bridge i7 running on a Giga MMO. He advised filling the three closest CPU slots and removing all RAM, recommending a quad kit with all four sticks in one unit. He also noted that dual kits were an option but had faced similar problems at the same store.
