i tried to install another version of win7 and then it worked!Now i cant find drivers for the ehternet,audio and pci modem and graphics card.Do you have any link to donwload them?
Compaq (HP) did not release any Windows Vista or 7 drivers for that computer. Their support for drivers only goes up to Windows XP.
You will have to download each driver from the component manufacturer's site and see if it works or not. The age of the unit is a key factor in something like this.
You can use either CPU-Z
to take the guess work out for you.
