Windows 7 Nothing on my motherboard works

Well when I installed Win7, I decided to put it on my old PC, that I didn't really care about... It was built to run XP...

Right when I was installing it, my screen went black, and said, no signal found on my moniter (im was currently using the VGA slot on the mother board) So, I put in some shitty ass video card I found lying around, and it was just a PCI slot card (no, its not a typo for PCIe...) And it worked. When I went to listen to music, when it was fully installed, I noticed the sound wasnt working eaither. The only thing thats works is the network slot...

They also do not show up on the Computer managment screen, I can't find the driver because I don't know the exact hardware names, and shit.

Any kind of feedback is welcomed

Thanks,

Kirus
