From my other thread I need a standard socket 478 retention bracket to mount heatsink/fan. [Thank you MAT ALAN :) ]
I found one on an old Gigabyte P4 Titan GA-8KNXP board so I decided to check the board before risking possible damage removing retention bracket.
I added suitable (old) CPU and borrowed a suitable memory from another PC (mine). The MB was resting on cardboard.
On connecting old PSU I saw the fan turn on the Titan module. Then there was a loud CRACK.
On re-powering, this fan no longer turns and there is no sign of life but no burning smell. The PSU does seem to have developed a rattle which I don't think was there before. Returning the borrowed memory results in Belarc finding it so I guess it is undamaged.
Two questions please.
1. Any idea what might have caused the short? I want to avoid any damage on further testing other items.
2. Any tips on removing retention bracket without damaging MB?
