Having a problem with my laptop

Hiya guys... I don't know if this is the right place to post this, but like the instructions said, u'll move it to the right place
Here's the thing. I have an HP Compaq nx5000 laptop and I ('cause I think I'm clever) rebooted and erased everything off my harddisk in order to get rid of some nasty malware that was bothering me. Little did I know, that I seem to have lost the support and drivers cd that came with the laptop. I've been on the HP support site, and downloaded everything that they post under my kind of laptop, but still I'm having some problems. For example, my bluetooth, inbuilt internet connection does not work and the multiple monitor feature doesn't work either. If anyone of you guys can help me, I'll be forever grateful
thx
