Help! :(

Hello everybody in tek syndicate, first of all I just want to say thank you for all of you who took time time to read my post in the forum I just recently bought a few games from steam, and I think my computer is capable of playing games that I bought, but the problem is... that I have my monitor plugged into the motherboard, and not into my graphics card. My graphics card is NVIDIA Geforce 8300 GS. I don't think its a bad graphics card to play games on, but the thing is... I put windows 7 professional a long time ago, and when I reinstalled my drivers for the graphics card it simply wouldn't work, it would make computer freeze till I rested it.I couldn't do anything that involves adobe flash. I don't know why does it I'm just hoping you guys could help. I would really appreciate it if I can have my computer to be fully functional again I really want to play my games. I hope I don't have to buy parts just to get it working. I'd appreciate the help you can give me.
