A couple small C90 Problems

Hello all!

I'm not real tech savvy, but the more I read these threads, the more I comprehend it seems. I put the specs of my C90S as my signature, if you need to see them.

1) Those 4 buttons in the top-right hand corner? The TurboGear and E-mail buttons don't work. They worked when I had Vista installed, but I downgraded. Since then, I tried re-installing all the utilities, and that still didn't help, any suggestions?

2) When I was looking for the driver and utility for my Wireless component, I ran my computer through some driver checking application (from driveragent.com), and it said that 41% of my drivers were bad. I scanned it again since then and now 37% of my drivers are bad (probably outdated). Where can I find the "good" drivers from?

3) my webcam shows a "this graph cannot preview" message, re-installing the driver didn't work, any ideas?

4) are there any other things I should update (like my BIOS) or anything else I should do to prevent any other problems from popping up?

I know there are people out there with more serious problems, but i'd appreciate the help

EDIT**- Since searching throught the forums, I was able to fix the email button, but the turbogear button still doesn't work. I also found out my gaming mode reboots my system when I click on anything.
