Have an HP Pavilion m9425f desktop, the NVIDIA GeForce 9500 GS video card fan has failed (again). Out of warranty, I am replacing with a EVGA GeForce GT 640 (Single Slot). I noticed there is a motherboard external/additional jumper connection (Blk & Wht 2 pin 2 wire - mboard label says PDIF out 2 ) to the existing 9500 vid card that does not seem to be on the new GT 460 EVGA card. Jumper needed? Motherboard video card slot makes all connections? What to do?
