Can anyone help me with this Minecraft problem?

I got a new computer about 8 months ago, and it's a beefy computer, with an i5 processor 32gb of ram and 8gb graphics card.

For the past 7 months, I've been able to play minecraft with 100+ mods, shaders, and a few different resources packs. All while watching YouTube on my other screen. No issued at all.

Recently, though, after playing my game for about an hour or two, all of my textures will turn pink. And after restarting the entire program, I'll get maybe 2 minutes before it turns pink again.

I've tried shutting down any background processes I can, watching YouTube on my phone, any combination of in game settings, allocating more RAM, optimization mods. But unless I turn off shaders and resource packs all together, my game will become pink soup.

I've become so accustomed to using shaders and resources packs that regular minecraft looks so ugly in comparison.

Is there any way I can keep them without seeing pink?

it could be a corrupt mod, id trying chaging them one by one, it could also be a texture pack thing, also check if you gave Minecraft more than 2gb of ram (its limited by default, you hae to changue it from the launcher), it might help :p

did you update your gpu drivers after you got your pc? if not you might wanna give it a try

also, is it only in minecraft or have you noticed any similar bugs in other games?

sounds like a graphics driver issue? maybe?

I would rollback to base Minecraft and slowly bring mods back to see what the offender is. Seems like an issue on that end if it’s Minecraft only, less inclined to think gpu driver issue, but to be safe you can always uninstall drivers via DDU, just make sure you have the driver installer physically present on your computer before you do. I genuinely don’t think you need to touch drivers though. 

I put the allocated RAM down to like 15000MB and that looks to have worked, so yeah I guess I was letting it use too much RAM and there was some kind of memory leak or something?

Okay so I did a bit more tweaking and I think I figured out what caused the issue

1. Too many world generation mods. I think this was the final change that fixed it for real. There was just too much stuff in the world. Though I kept Feature Recycler just to be on the safe side.
2. I took out Fresh Animations, I have mods like ZAWA that it doesn't work on anyway so it's kind of a waste to keep it, I'm sure it was conflicting with Oculus anyway.
3. Cleared out all of the config files and cleared out the ModernFix cache. This completely reset any graphical changed I could have made. And I decided not to change any graphics settings either.
4. Removed a bunch of optimization mods and replaced them with c2mef. As well as installing Lithosphere which probably helped get rid of any weird terraforming glitches that could put a strain on the processor.
