Graphics card issues

[pcmr69420666]

i just bought a EVGA GTX 980 from ebay and today when i tried to put it in my pc, there was video, but there was lines all over it and it would randomly crash. i tried installing the latest nvidia drivers and when i opened the they said 'an nvidia graphics card was not detected in your system'. i uninstalled the amd drivers from my integrated graphics already. i dont know what do to. i dont know if i got a bad or dying gpu or if its my OS or the drivers or my BIOS. please help. im running windows 11 with the insider program and my specs are Ryzen 3 3200g, MSI B450 A PRO MAX, 16gb 3200mhz corsair vengeance rgb pro ram, samsung 870 500gb sata ssd and an aresgame 850w psu

Do you have a picture of the lines on your display? Sounds like bad card.
