Thanks a lot. Your help has helped me a lot!
My last question. I think there is a possibility that before your advice I could have installed an incorrect driver. There was once that the driver installer told me my computer didn't meet the requirements so I am assuming that it was the incorrect driver. If I happened to have installed an incorrect driver, is there any concern? Is there any way to detect if I installed an incorrect driver, other than my computer acting strange (which I have not yet noticed)? I don't think I would make that mistake with your advice now.
Once again thanks for your advice!
