Hi, I have a problem with my graphics card. I know it's compatible and everything is working properly as far as I can see. The new graphics card I have doesn't want to seem to work. The fan runs and the pc starts up, but there is no display on the monitor. If I wait long enough, the computer makes 2 short beeps and nothing else happens. I'm unsure of the graphics card model, but the brand is Radeon and the computer brand is Lenovo. My old graphics cards are disabled already and mt BIOS is up to date.
