Got new hardware recently, trying to install it into an old HP pavilion tower (fx 6120, radeon hd 7450, 1tb hdd, win10 64). When I put the card into the tower and turn it on, the fans spin up and the led turns on, but my monitor doesn't detect anything. Also I can tell that it hasn't booted into windows because of how quickly the computer shuts off. The last bios update for this motherboard was in 2013, and I have the update from 2012(bad internet today, can't even download a 4mb file). Full specs:
fx 6120
10gb ddr3
radeon hd 7450
evga 600w
1tb hdd
120gb sata ssd
windows 10 home 64
