Here are the drivers: http://esupport.sony.com/US/perl/swu...?mdl=VGNFS715W
The chipset drivers are under Motherboard.
They seem to be mainly original, not updated drivers, but I would run them anyway. Check the order of installation I mentioned, Chipset -> Video -> Audio, you probably don't need others if they seem to be working, maybe Network and Wireless, but you might need to identify the controller. Get the System Components drivers.
It would good to download SIW (see my signature). It will tell you a lot about your system, oh, see this: http://www.windowsbbs.com/adding_sys...fications.html
but, it may have a little trouble reading Sony's specific information and you need a good chipset drivers for it to work correctly.
The chipset is the "secondary" chips on the motherboard that feed information to the main CPU
. They "oversee" all the other hardware controllers (graphics, audio, etc). If they don't have a good set of drivers, the data cannot get to/from the CPU
to be processed.
Check that your games are suitable for your system (check the System Requirements for the game). They might not mention mobile graphics adapters and usually not Intel adapters at all. Were the games
working "perfectly" before you reformatted?
