HP's link to product information leads to a blank help page, as always. Remind me to never buy HP...
I found someone that had conveniently posted SiSoft Sandra specs on your exact laptop. It uses an ATI integrated IGP9100. The bad news is AMD only offers Windows 98 and 2000 drivers... this is an ancient piece of hardware. You're welcome to try to install it but chances are it won't work in Windows Vista or 7.

Without a fully supported graphics driver, advanced graphic functions like multi-monitor setups will likely not function. All I can suggest is upgrading to a newer laptop...
Now about sound...
It uses AC'97 fax modem (!) but for sound, it is a SoundMAX chip. In other words, not Realtek.
This looks like the last driver made for it. This driver is designed for XP 32bit, so it may not work on 7, and if you're using a 64bit install it won't work period.
