Sounds like the cpu got hot and shut down due to the fail safe. Then you turned it on again and it got even hotter for the few seconds it could and shut off again. Off hand Id say cpu. Can you see any damage to the mobo where it broke off? Being plastic this item would have nothing to do with the electric workings of the mobo. ie no grounding issues. Any idea how or when it got broke? Might of been broken awhile, not really doing its job and this is just the end result...
Get the bracket and see what happens after you install it. X figures for ya here! Good luck
