I downloaded an update from Intel website, seems it is an updated driver for WinXP.
So what you gonna do is, DL the driver on http://downloadcenter.intel.com/SearchResult.aspx?lang=eng&ProductFamily=Graphics&ProductLine=Laptop+graphics+controllers&ProductProduct=Mobile+Intel%C2%AE+915GM%2fGMS%2c+910GML+Express+Chipset+Family&OSVersion=Windows*+XP+Professional
Then once done, do the following:
Right click - properties
Set it to WinXP SP3 on compatibility mode
On priviledge mode, run it as administrator
Apply - Ok
That's it, this should work like a charm!
Hope this helps you guys if ever you still need it as this post is older than 7 month.
