My monitor get display when pc is running on onboard gfx but whenever i install 4850 , for 1-2 attempts screen shown weird colours but windows did not detected any external gfx card hence i was not able to install catalyst too ... now there is no signal to monitor ...
HDD: 160+250 GB
Monitor: Dell 22" HDMI,DVI,VGA
PSU: Coolermaster Extreme Power Plus 500W
Graphics Card: Palit 4850 Sonic
Well I was running same card for 4-5 months ... but one day there was no display , i thought there is some prob with card so gave it to service center ... back from service center , there was same problem ; No display...
So m not getting whether its problen with monitor DVI port or PCIe slot of mobo isnt working ...
