Hey guys. I have an issue. My computer, which i built about 2 years ago with my father, crashes about once a day, usually not long after booting it up from a long rest, and has hangup issues whenever loading a piece of software, often the screen flickers purple and then back to normal. Programs will crash and usually i'll be able to anticipate a crash when several things start breaking in sequence. What should I do? I'm almost positive it's a RAM issue but i'm really not sure. I can't update the graphics drivers without it completely failing and requiring a system restore. Could I get some help? Online searches aren't doing me any favors.

Specs:
-Motherboard: B550 Taichi Razer Edition
-OS: Microsoft Windows 10 Home
-Processor: AMD Ryzen 7 5800X 8-core processor, 3801 Mhz, 8 cores,16 logical processors
-BIOS: American Megatrends Inc. P1.30 12/1/2020
-SMBIOS 3.3
-ASRock board manufacturer
-4 TridentZ G Skill DDR4 16gb RAM sticks totalling 64GB, and i believe they're 3200 mhz
-AMD Radeon RX 6600 GPU


I've tried replacing the graphics card once since at first i thought that might be the issue and it didn't work, I'm FAIRLY certain it's a RAM issue but i want to double check with ya'lll, it's been like this forever, not once did it NOT crash, so it's either something faulty, or some incompatibility. When i crashes i'll usually get issues like DPC Watchdog violation, kernal security check fail, pagefault in non paged area and memory management. If I could get some help that'd be greatly appreciated.
