You need another pc you can install it in to test.

But you can remove it, then reinstall it to make sure it is seated in the slot correctly, it just may have come loss.

Also check the device in manige, right click mycomputer, manige devices, look for the tab videocard/ display card setting. See if it gets picked up there, if it does you need to reinstall display drivers. If it doesnt display there, you can right click properties, go to adjust screen res etc, see if a higher one is greyed our, if greyed out you qlso need to reinstall driver. , but atleast the card is picked up. If not, follow addrams advice and see if it is seated properly in the slot and the monitor/s conected properly etc
