Well....I doubt you will hurt anything unless the drive is writing at the time you press it.i am just pushing it you normally would do.
i have the ram set to 3200 MHz. but when checking in task manager, the ram is running 3200 MHzsounds like the bios is having a hiccup, maybe ram is stopping it booting normally and bios is booting in default mode, have you any changed settings in bios like xmp or something else?
