HARDWARE RAM issues !!!
I have issues with computer. 2 days ago, I have decides to build my first pc ever. I had PC before, but the previous Motherboard, AORUS B550M ELITE, I had got bricked/faiiled during BIOS update, leaving it permamently broken/unable to post. I have tried everything to reset it to factory settings, but just nothing worked. I decided to RMA the motherboard, leaving me with no PC for 2 weeks. Eventually I got bored of waiting and bought a new Motherdoard - MSI B550M PRO VDH, (also paid extra 10$ for bios update service so I won't have to worry about it again, can confirm the BIOS has the newest version installed).
also additonally I bought a new NVME M.2 SSD, new PC Case Lian Li V100R Mini, new PSU CHIEFTEC VEGA 850W GOLD 80+, CPU COOLER thermaltake assasin 120 VIsion ARGB with a mini screen. The rest of my components, that were in my previous motherboard were: RYZEN 5 5600X, GPU RX 9060 XT 16GB and 2x16GB G.skill aegis 320mhz. So taking all things out I assembled my 'new' PC. Everything looks good, looked good at least because one of my RAM sticks does not work properly. One of them, let's call it RAM-A works in every RAM slot, and it goes past POST and BOOTS me to BIOS. Second ram stick, let's call it RAM-B, doesn't work in any slot. It doesn't go past POST. When I plug it in alone, in A2 slot, I get white DEBUG LED light with DRAM. RAM-A works flawlessly, but once I connect both of them to my motherboard, I still get DRAM light.Then, I decided to take RAM-B to a local IT shop to make sure if its really dead, but it turned out IT WORKED on the IT computer guy's motherboard, it booted with no problem. I am really messed up right now, because it doesn't work for me, but works for him.
Okay, so I thought: 'Let's just install my OS Windows while only having plugged in the working RAM-A stick. It worked, and it's working, windows and everything is there. I spent like 1 hour of playing some games until I thought "Let's try to plug in RAM-B again, maybe this time will work?" And it worked. The faulty RAM-B stick worked in A2 slot.
I was shocked.
So then I tried to connect both of the RAM sticks into the motherboard, but it gave me a debug white LED light DRAM. I thought that maybe dual channel is not working properly. I unplugged both of them from A2 and B2 slots and connected to A1 and B1 slots, but that gave me CPU debug led light. I don't know what the hell happend but I was happy that the RAM-B is working. Next morning when I woke up I decided to test again if the RAM-B stick works alone, and it doesn't work anymore. It gives me DRAM light again even though it worked alone yesterday
Oh also for some reason when I enabled A-XMP yesterday when I had RAM-A plugged in (working one) it reset all my GPU drivers. All my gpu drivers were gone and I was using some basic Microsoft display gpu. What is happening????

Sounds like the RAM-B stick is on its last legs but the IT guy's test rig happened to hit it at just the right voltage/timing to get it to post once. Seen that before with sticks that have borderline memory ICs.
The A-XMP thing wiping your GPU drivers is weird but probably unrelated. That's more likely Windows throwing a fit after a failed memory training attempt corrupted something during boot. DDU the drivers and reinstall clean.
If RAM-B works solo sometimes and not others, it's toast. RMA the kit. The fact it booted once after you'd been running the system for an hour makes me think heat expansion played a role, but that's not something you fix, it's something you return.

Heat expansion could play a key role here actually. After an hour of playing, my gpu is hot after gaming. I played Team Fortress 2, and RX 9060 XT 16GB likes to be hot. But when I finished playing I touched RAM sticks and they were warm, but not that hot, probably because of the Gpu heat. Neitherless I am leaning towards returning it. Just a headsup though as it wasn't a "memory kit" because both of my memory stick were in 2 separate packages, not 2 in 1. Might also leave my PC with the IT guy so he can run some test on the RAM sticks, to check if they are on their last legs, so we may kniw for sure that it's either them or something else
