so i sent it in to intel but rejected it because of the "thermally damaged circuit board." however, when i sent it in to them, they had me put the little cover over the cpu area and in the process, i think it damaged a couple of the pins (they won't go back in.) do i dare put the CPU back on it (to try to fix the bios again)

No. If you've damaged the socket then your motherboard is junk. It is possible to get the socket replaced but it would be expensive and not worth it.

R.I.P.
