I recently bought a palit nvidia geforce 620 graphics card and im having trouble getting it to work. I plugged it intothe motherboard and the computer works but the graphics card fan spins realfast and is very loud. When i plug my power cable in however (pcle) the fan slows to a sensible speed and becomes quiet but the computer wont boot.
What am i doing wrong? I am a rookie so please dont expect me to know everything.
