need a little more information before i dig in here. is windows 7 x32 what this system shipped with?
If not it might get a little sticky finding drivers.. but heres what i do, and i haven't not been able to find a driver (for windows) yet.
Start>control panel>hardware and sound>Device manager> a new window will open, in that window, right click the item(s) listed with a yellow !>select properties>a new window will open>Details (tab at the top)>you will see a drop down box labeled "Property" change that to "Hardware Ids"> now right click the items listed below and copy them, then paste them into a notepad or word, then take that string that should look something like,
BTHENUM\{936da01f-9abd-4d9d-80c7-02af85c822a8}_VID&00010075_PID&0100
and Google it. like so
a few words of wisdom, don't be afraid to try drivers from other manufacturers. Do try to stay clear of sites that are not manufacturer website.. awhile back crafty website masters realized that windows system drivers are highly searched for in search engines. because of that many bogus websites have sprung up that will try to force you into downloading some crapware, or other unwanted junk.. so, look at the URL's in the search results before entering a site. these fleabags are very crafty, read and reread the URL Google lists before entering a site. use your best judgment though, if the site is like www.overclock.net, it's likely ok (in that case its more than ok it's a good bet) but I'm talking about URL structure, if that URL were to be windrivers.overclock.net (notice the "." between windrivers and overclock.net) I wouldn't trust it. that is what's called a sub-domain, and widely used for spam sites..
just for the sake of clarity overclock.net is a solid community, and great site. just using that URL as an example.
for the most part when you search by Hardware ID, you won't see too many bogus sites, but better be safe than sorry.
goodluck~!
