I was checking another site and found a link to IObits Driver Booster, sounded good had to try it. As far as I can see it does everything it says it can. Found ten drivers on my tower, 7 on my Toshiba LT and 16 on my Acer mini. On my tower everything went quite fast about 15 min start to stop, big lap top 25 min, my poor little mini is still battling it out. I would recommend trying it, all manufacturers drivers get out dated fairly quick.
The down load does have little junk attached, going through the initial applets you have to decline the IO tool bar it jumps to the next one and continues thi install. Watch the last applet they sneal one more tool in, I let it through on my laptop looked it over and did a Revo on it. Note does run slow machine on a lower spec machine, patiance is a virtue the wait will be worth it. It may be an answer to the diver issues many of us suffer through.
