I have the HP e9280t from 2009, I'm here today asking for help on how I can install this graphics card sapphire hd7870 . Whenever I try to boot up the PC with the graphics card plugged in, it simply just beeps 2 times and one long beep. How can I fix this? I have checked and this graphics card is compatible with my system and the PSU should be okay with the graphics card. Help please!
