yeah, you need the 4 and 24 pin plugged in. when you removed the heatsink, did you reapply thermal paste before reseating the sink? and did you plug the cpu fan back in? sounds heat related.

did not replace any paste...not that knowledgeable im afraid... it stays on for roughly 3 to 5 secs...could that be due to paste

both 4 and 24 were plugged in when i removed and cleaned heat sink...all back together , fans work, old past still in place but not new, i removed the 4 pin troulble shooting from another web site to see if it stayed on and it did with 4 pin disconnected, but shuts down in 5 connected, not sure that it means anything what so ever, checked power from 4 pin but not sure what i should read.. was less that a volt
