I had to send my computer back to the manufacture because of internet freezing and random re-starts. When I got it back I was told the problem was an obscure driver that was bad (made that way by a microsoft update). They didn't list what driver they replaced it just said "replaced a driver". If I ever go and re-format the computer, I would like to know what driver they replaced so I can then do it myself. Where can I find out in my computer what driver was replaced? System restore listed nothing changed. Thanks.
