i recently installed a new graphics card, a dual-x r9 270x Radeon graphics card. When I turned on the screen there was a black screen saying there was an error with one of the cooling fans.I disregarded the message and installed the software for the card and wanted to see if the card worked. I started playing a game and within an hour the game started acting funny and I noticed the tower was putting out a lot of heat. I turned off the computer as quickly as possible and let it cool down. When I opened the tower I found out that one of the connectors from the power supply to the card was not connected all the way so I fixed it. When I turned on the computer I got two beeps and a third long one and found out it meant an unreadable graphics card... I've tried cleaning it, removing it and making sure the connections are plugged in. I can't seem to get it to work.
Can someone tell me if my graphics card is no good anymore or if I can maybe fix it
