Hi guys, I'm trying to install my graphics card (GeForce G210 512MB DDR2 D/HDMI) To my pre-build gateway desktop pc (Gateway SX2802-02c) But when i place the Graphics card into the PCI slot then like, Hookup all the pc cables (the power cord,mouse,keyboard,monitor) and press the power button, The pc doesn't turn on but a yellow light turns on where the power button is, But when i like, Take out the graphics card it works again. (Normally the power button light is blue, It's yellow now) I was going to take my pc to a computer repair shop, But a friend suggested that i post my problem on these forums, to see if anyone could help me. Like a second opinion i guess. Anyways! Thanks for reading.
