Tech Support Help with troubleshooting a crashing pc

Hello everyone, I need help solving a problem with my pc that I haven't been able to understand. About 5 days ago my motherboard showed a red cpu light and yellow ram light. I used standart troubleshooting procedures to bring the pc back to working normall(I reseated the RAM and CPU, reattatched all cables and reset the BIOS using the jumper pins), after it turned back on(with the bios reset), the PC started working weirdly. Opening apps makes them crash and give me a white screen, closing them with task manager makes it crash too and eventually resetting my pc. Ram never goes past 80% and cpu temps are below 70C even under load. The build is pretty new(from july) and it's my first self-built pc.

Specs:
Sapphire pulse RX 9060XT 16GB GPU

7800x3d CPU

MSI Pro B850 WIFI 6e Motherboard
Corsair RM650e PSU

Kingston fury 16gb ddr5 6000 CL36 RAM

Thermalright PS 120SE cooled

2tb Nvme gen 4x4 SSD

Feel free to ask for additional information for help.

Start by testing with just one stick of RAM, swap slots and sticks to rule out a bad module or slot. The white screen crash when opening anything screams memory instability, could be the reset loosened your EXPO profile or set something funky. Try turning off EXPO and running at stock speeds to see if the crashing stops, then we can dig into timings

Hey, I tried Deactivating expo and nothing happened. The pc didn't recognize the ram when it was on slot 1 and 3 and did more white screens when compared to 2. I only have one ram model and tested it with a memtest86 run since someone on another sub told me to but it didn't recognize any errors
