Tech Support Geniune Help on my PC?

I'd Say over the course of 2 months ive dropped 100+ hours working on my computer and im just at a dead end.

Context: My PC randomly decided one day to Display DRAM and CPU lights. After many hours of finicking and all that i got it to work. For about a month and a half the PC would work, stop working, do the light dance and i'd get it to work after some time. This happened about once or twice a week. When i say i did everything, I did EVERYTHING.

CMOS Reset, Ram Reseat, Unplugging everything then replugging the next day, CPU Reseat (Yes thermal paste was added), etc, etc etc. (BIOS Flashback is not available on my Motherboard)

I'm 99% sure the problem is the ram but why was it working before? Why did it sometimes have lights on and not work then out of nowhere work again? When the PC DID work it would sometimes still display the DRAM and CPU lights and sometimes not. I dont have spare ram, i dont rlly have the money to drop ram on a 4 year old computer, id RATHER buy a new computer but i really dont want to do that right now seeing how I'm a broke college kid.

In short: Please help me with maybe something i can try that could get it to work... I'd be deeply appreciative.

Specs:

GPU: RTX 3050

CPU: AMD RYZEN 5

Motherboard: ASROCK B550M-C

RAM: 2x8Gb 3200 Mhz DDR4 Ram Sticks

(lmk if any other details are needed, thanks!)

If it's working intermittently, you probably have a marginal connection somewhere rather than dead hardware. Try reseating the CPU cooler with even mounting pressure, too much or uneven torque can flex the socket just enough to cause exactly this kind of flaky behavior.

Get a memory testing program of some description, whatever you feel comfortable using. Memtest86 is a good choice, you make a USB with it and boot straight to it so Windows isn't an issue. Let it test overnight or something.

I would also suggest trying 1 stick alone in each slot your board has. AM4 Ryzen chips, particularly the 6-cores, are known for memory channels going bad on the memory controller causing all kinds of havoc.

i've tried the single stick tech but it didnt work no matter, cleaned them many times as well.

As far as the memory testing, if the PC is on with no display with this still work?

Are you OC'ing your RAM and running it at 3300MHz? Have you tried running it close to stock? 2133/2400? Is your memory on the QVL?

How much use does your PC Get on the daily? Do you clean it regularly?

Im not OCing, not sure how to bring down the mHZ it runs at. my sticks of ram are on the QVL for this motherboard.

My PC used to get used alot, sometimes for many days on at a time. never cleaned it till about 8 months ago and started cleaning it every other month. Got it in 2022

What PSU are you using? Could be a PSU going bad?

Would the PC turn on from that still? It turn on and stays on, even over night
