tethering problem

what type of driver do i need?

ok everyone i fixed it. it was driver issue...my computer is sony vaio vgn-fs920...and the driver it was runing was xp...and since there is no 7 drivers for my model i used vista..and it worked..

I slightly droped my laptop on side of bed..wasn't a hard drop now it goes to operating system not found...I don't have windows 7 cd..I bought laptop off of somebody..so I just try installing xp ..booting from cd...but says can't install because no hard disk drives found....what do I do??..I also read somewhere that someone had this problem ..took there computer apart ..found that something wasn't pluged and it was fixed..any ideas other than that guys??

Recently bought a netbook with windows 7 starter OS. Tried to tether with my HTC Snap but cannot connect. I have a laptop running on vista and had no problem tethering with my HTC. What could be the problem? Message i'm getting is on the driver. When I tried to update driver, it says I have an updated driver. I never had any manual installations done in my Vista laptop nor errors such as this. Is this related to the Win7 OS?

Please help. I bought the netbook since I'm always travelling and tethering is my only way of connecting to the net.
