Some drivers for Vista work with win 7 : go4download. com/ Compaq-evo-n610c-drivers don't leave the space between the dot and com and from / to Compaq is the only way that tomshardware let me show you this site.
I've had pretty good luck installing a variety of XP drivers in Windows 7 by doing it in XP compatibility mode. Right click on the driver installer, select properties, compatibility tab, check the box to run in compatibility mode, then choose XP SP2 or XP SP3 as the mode. Then run the driver installer.
