wtf, all ram back, gpu back, original psu... goes to bios just fine
@f0x bad seated ram?
@stapper messed up ram it seems, from memtesting in various configurations
@f0x memtesting can mess up ram?! Damn
@stapper ah no, it was memtesting that showed the ram was messed up, with loooots of errors
memtesting was very fucky, and new motherboards for this cpu seem difficult to source too...
i have a decent upgrade list thanks to @erikk@chaos.social so might just go for that in the end
