wtf is wrong with my computer (hexbear.net)

recently there has been this problem that has been getting more frequent, my computer just randomly freezes up/blackscreens and then fails to post when i do a hard restart. this doesn't resolve itself until after i open it up and play musical chairs with the ram for a bit.

shit that i have tried:

swapped the ram around to different slots. sometimes it works, sometimes it doesn't
cleaned out the case
wd40'd the ram pins (helped with the posting but seems to have increased crash frequency, not enough data to tell for sure)

no idea where to begin with this one, can't tell if it's a motherboard or a ram issue or something else entirely. the sticks are of differing sizes and manufacture so that may also be an issue. would give specs but the thing just died on me in the middle of posting this and i can't boot in just yet. motherboard is a supermicro x9 something server board.

This could be any component, including MB, CPU, GPU, power supply. This could be damage that temporarily fixes itself once the thing cools down again. You'll want to remove as many components as possible, and swap out the rest with alternatives, or swap your components into another computer. Maybe you know someone you can visit to swap stuff out with?

Also, have you tried running memcheck86 on the RAM? There's also other diagnostic software for other components.

Just running a stress test like a benchmark might reliably trigger the problem, so you have a reproducible way of triggering the issue instead of just waiting for it to happen.
