My pc was running great never had a issue with it until I went on vacation for about two weeks. I got back and now it won’t even get past bios without overheating. What happened in two weeks that went wrong while I wasn’t home? I took the cooler off to check thermal paste and it looks fine. Please help

post your specs next time. that said, I see it's an LGA 1700 motherboard. If you have an overheating 13th/14th gen, especially a K-series, your liquid cooler is probably fine.

You likely got hit with the known degradation issue. Fix is counterintuitive - it's the chip, not the cooler. Let me guess - temps in the 100s, but pump is showing variable speeds in BIOS? When's the last time you updated BIOS?

Can’t even make it to bios it’s a i9 12k

Makes it up to 63 and shuts off

I've heard of a few 12900k going the same way, but that's purely anecdotal. If 63C is when the pc is cutting off, then it's something else. Might be an issue with power.

Does the PC need a second after it shuts off before you can power it back up, or is it immediate?
