I recently bought some used parts. A Asrock p67 pro3, 16gb ram, i7 2600k
when i launch the system task manager shows insane clock speeds then pc bluescreens when i try to run a cpu intensive task. I tried different cpus and they work perfectly. I also tried this 2600k in a different motherboard and it works perfectly too. No idea what could be wrong. I resetted bios and windows installation a few times..
