Bo

yeahhh first, boot the previous kernel 😂 in GRUB pick Advanced options (Debian/Ubuntu) or the older entry in teh list (RHEL family). if the old kernel boots, ur data is fine and the problem is teh new kernel or its initramfs.

Warranty matters a lot, i don't want to figure out which part is broken if something fails. idk what else to say tbh

reset any overclock or undervolt, especially meomry clock. artifacts that look like small coolred blocks are often VRAM instability, and a driver update can change memory behavior eonugh to tip a marginal OC over. worked for me anyway 🤷

lol same thing happened to me this. so much this
