This might be an extremely noobish question, but I need to know about it. I had bought a CM600W PSU and a GTS 250 512MB, but since I was staying with my cousin, I had the two installed in my cousin's PC (by the vendor). Now, I am going back home and taking the PSU and Graphics card with me. I have a question: The graphics card was installed into a PCI-E slot and was held in place by a retaining screw. When I removed it, I didn't take the retaining screw and used it for my cousin's card. Is the retaining screw just like the other normal screws that hold the cabinet/PSU in place? Or is it a special one which I need to worry about? It looked like an ordinary screw to me, but I guess that it won't hurt to be sure. Sorry if this is too noobish, but I would rather be safe now than sorry later.
