Welcome to the "I built in myself" club, Librider! :biggrin: You made a very basic, but very common mistake. But you LEARNED and you did it YOURSELF and that's the most important thing. You're discovering that putting together your own PC is pretty easy and it's rewarding. Good on you!
Your motherboard came with a driver CD. Load all the drivers from there. It's a good start. You will need to load the Intel Chipset, LAN and Audio drivers. Possibly a separate USB 3.0 driver too. Running the CD on "Auto" or "Load Drivers" should load everything.
Windows 7 will have a driver that works for the GPU, but it's way sub-optimal. For the GPU, go to
www.nivida.com and download the latest driver for your OS and GPU. It is version 306.97, FYI. Also, check with the manufacturer of your monitor and see if you can load a driver for it too. A lot of people skip this step. It's not absolutely necessary (obviously, you can see stuff on your monitor) but w/o the driver, you're not getting 100% from your monitor. More like 75%-ish. You're almost there!
ps
Does your monitor have a DVI connection? You should be using that, no a VGA connection, if it is supported. Much clearer picture.
