connection problem

hi there,

i need your help guys! i format my HP dz2450 compac microtower to WINXP SP2 and everything looks fine, but when i tried to connect through internet, there was no connection at all and i found out that there is some "yellow?" in my device manager, like PCI bridge device and SM Bus Controller.
i tried to uninstall and scan for hardware changes but still the problem still there. and i tried to update and it ask me about this driver/17519/win2k...

what shld. i do to resolve this kind of internet connection problem...

pls.... pls.... pls....

 

It looks like you need to install chipset driver.
Go back to HP site and get it.

 

is it a yellow exclamation point? That means your missing a driver just install it should be able to find any of them on the Internet and put it on with a flash drive.
