hi! recently, i purchased a copy of windows vista, and i installed it over my windows xp. i deleted my whole xp partition, and installed vista in this partition. however, i was unsatisfied with vista, and switched back to xp. however, once i installed xp, i noticed my computer was getting a bit slower. i tested a few games on it, and it indeed appeared to be slower. i went back to vista, hoping for better results, but i ran into the same wall. since then, i have been desperately switching back and forth, searching for a solution. my brother thinks my computer is slow now because my BIOS has been damaged, due to the repeated switching of OS. Can you please help me? Thank you very much .

This is more likely caused because when you reinstalled XP you didn't install any of the drivers for the hardware - things like sound cards, graphics drivers, etc. In their default state with generic drivers performance isn't exactly pretty. The same is probably true of Vista - need to install drivers for the hardware. You can get them from the motherboard CD that came with the computer, or you can download them from the people who made the computer.

I forgot to mention that each time I reinstalled a OS, I used the "Drivers and Utilities" CD that came with my computer to reinstall the nVidia drivers, as well as the other drivers. Could it be that due to the repeated installation, the CD somehow wore out, and the driver files are damaged?
