Specs: Vista home premium, Inteo(R) Core (TM)2 Duo CPU T6400 A 2.00Ghz
I have been leaving my laptop on 24/7 for the last few weeks, and all of a sudden, wireless and direct cable connection to the internet start running extrememly slow. Wireless is connecting at 54mbps and cable at 100,,, but still internet pages load at snail pace.
All other functions on the laptop run fast as! task manager shows cpu running 2-3 % , so it's not the pc by the looks of it.. i have tied my mates laptop on the wireless and cable, both run fine on his pc. and internet pages load extremely fast.

I already went back to a system back date from a week ago, when the laptop was running fine.
i visit no wierd sites at all,, so i am puzziled.
I have run Glarys Utilities, it cleaned up what it found, but no bugs,worms, or adware

here is more info from the laptop
