Do you have the Windows Vista installation disk?
This could also be an OEM repair disk supplied by Compaq computers.
There is a possibility your drivers were corrupted or removed during the cleaning process of the Malware, this often happens because the malware can infect those drivers and if they are flagged they will be removed from the infected system.
System restore can only be effective if you roll your system back before the actual date of the infection, because your restore files can often contain the infected files.
I hate to say this, but in a lot of cases, a clean system is not always clean, it sometimes takes a complete reformat and clean operating system install to render a system clean of all possible signs of an infection.
System files can become corrupted and unstable once they have been infected, the cleaning process removes infected portions of the files leaving the remainder of them unusable by the operating system.
If you have a copy of Windows Vista with the same service pack on it, it is possible to install Vista over Vista without losing your entire hard drive contents, it will simply replace all of Windows Vista's files with original uncorrupted virus free files from the system disk.
This can also be done if you have an OEM disk, you can legally use someone else's Vista disk to do the repair as long as their disk has the same service pack as yours and you hold a legal license for your OEM version.
Any questions, please don't hesitate to ask.
