So I just installed windows 7 yesterday...I was browsing through my system properties just now and noticed that my computer thinks I don't have a graphics card. I know I do, it's an Nvidia something or other, and it worked fine when I was on vista. I used a search to see if it would find it, but nothing came up. I'm thinking and hoping that maby i just bumped it wrong and a pin came undone or something...any ideas or suggestions since I'm not a comp genius? also had a seperate question....I noticed my laptop says its capable to run 64 bit on it, whats the difference between 32 bit and 64 bit? you can disregaurd this.................I think I just found the problem. still would like to know the diff between 32-64 bit though.
