Probably the best thing you can do is a fresh install. This way you don't have the HP bloatware!
Do a fresh install (boot off the Win7 CD - I'd suggest the 64bit version)
Patch and update 7 completely.
Then look in device manager for the devices it couldn't find drivers for from MSFT.
Use HPs site, with a little time you'll be able to drill to your exact system, and they host all the drivers there. Only install drivers, you shouldn't need any "utilities".
Note: You may need to download a network driver to get internet connectivity initially. Use your desktop and a USB drive for that...
Let us know if you need help beyond that.
