Posted October 13, 2016 i switched my Geforce 9400 GT for Sapphire Raedon RX 460 2GB a few days ago. installed the new GPU and connected it with DVI-D cable. But monitor receives no signal. GPU fans were spinning. replaced new GPU with old one which uses VGA ; display works. what is going on ? some things to keep in mind are : 1) GPU has no external power supply slots , i triple checked. 2) I have a 450 Watt PSU , the GPU needs 400 minimum. 3) The DVI-D Port on my old monitor has not been used for 6 YEARS , i think that it may have been broken by dust/rust. 4) No beeps from the Mobo when i start PC , it just says no display signal. SPECS : Intel Core 2 Quad Q8300 @ 2.50 GHz Intel DG43GT Nvidia Geforce 9400 GT (old gpu) 450 Watt crappy PSU 2 x 2GB DDR2 RAM Windows 7 64-bit 500GB HDD Samsung. Help !

Posted October 13, 2016 Put your old GPU in, run display driver uninstaller (DDU) to uninstall your driver (especially important when going from one brand to another).
