right been reading the business side at hp, its the only way to find possible answers sometimes as the standard support sucks.
they say this may be your wifi driver.
i have my doubts over that to be honest i would think it might be this one myself.
microsoft UAA ( if not already installed )
geforce GFX card
( i know this set work as a few members have already installed it )
your going to need everest as well and that you can download from here and i will tell you why.
your need the everest ultimate download http://www.davesdrivers.com/forum/showth...24#pid4024
if your wifi still refuses to work with the list of drivers above i will need you to do the following.
install everest, and run it.
look in the left hand list and click the little + next to network.
click pnp/pci network
let me know what cards are listed by everest.
sm bus and co cpu drivers.
these two need to be fully unpacked and installed from device manager update driver option
your sound is still going to be a problem but once the UAA is installed and device manager then list's unknown HD audio on such and such bus we can try and track that down.
doing downgrades is not as easy as some people think, it takes time and try this and try that.
most support sites and tech people just won't do it as you need to put in lot of time and effort and most of all leg work on the net to find the answer's
on here i have helped countless people with downgrading and something i enjoy as the answers don't come easy.
