I got a new motherboard for a backup computer and i didnt have all the stuff for it so i put it off too the side and over time of it sitting around the heatsink off the top of the northbridge came off!! ( came undone from the glue holding it on to the chip. is it still good? or do i have too take it off and scrape the glue off and reaply it? there is two tabs on the heatsink that might prevent me from taking it off the board. please inform me of what too do.
