Alright, I have more or less everything set up now. Still no beeping sound, I don't think my case has a speaker, though its not much of an issue since my computer is up and running with all the basic programs installed.
But! The video card problem is still there. I tried going into the BIOS, but I couldn't find the option to boot to the PCIE, and it continues to boot to the internal Intel card. Device manager still doesn't recognize the card at all, so I can't install drivers to it (the Nvidia installation thing tries to detect your card, and if it doesn't, it doesn't go ahead with the installation).
Is there a reason it wouldn't be detected? Googling the problem just suggests that I either reconnect the card (maybe I didn't use the right wires? I used the ones that came with the PSU, not the ones in the video card case) or that my PSU isn't powerful enough. I'm not thinking its the PSU not being powerful enough though.
