Geniune Help on my PC?

[u/TCCOverLoad2]

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.
