Go to the device manager:
Start, Right click my computer, Properties, Hardware, Device Manager... it will display ALL of your computers harware and allows you to update the drivers if needed or to "ROLL BACK" the drivers if an error happenes... you can also create a txt file and then rename it to "anything.NFO" and when you open it it will say an error, just clkick okay and all your computer information like how much hard drive space, cpu, ram and operationg system version you have..... i know theres an eiser way to do that but im not sure how.
