Gt 610 fan on but no signal?

A few years back I bought a gpu for light gaming like Minecraft and stuff my friends got new motherboard and processor so I got his old one my graphics card wouldn't work with it I have no onboard graphics i tryed all the ports on like 5 different monitors and tvs still nothing.

Its not unusual for graphic cards to play up especially when they haven't been used for a few years, however the problem is probally within your bios
on your pc press the power button then hit the "delete" key ( or appropriate key ) to enter the bios and when there locate the option marked "init display first "… This tells the bios which graphic card/adapter to use and you need to change this to "pci-express" or "peg"… Then locate the option "onboard graphics "( on the cpu ) . And make sure this is disabled ( if you can't find it don't worry but make sure the "init display first" option has been changed ) … Finally before exiting the bios make sure you press "save and exit set up" on the main bios screen… Your pc will restart as the changes are made
note: you may need to use another graphics card to see the bios so bare this in mind
you may also want to reset the bios as this can fix many problems… Locate the cmos battery on the motherboard ( round silver coin shaped battery ) and remove this for 20 seconds before placing it back… This will reset the bios and may fix your problem but you may also need to reset the time and date and any other user specific settings you have made
I hope this helps Austin… Any questions let me know
