Well this system has all ways had trouble with graphics drivers. The only one offered through HP for this system is a year and a half old and causes games and such to crash. I have many games through Steam and there system scan tells me that this driver is a problem. I can not download a driver through ATI because this is a prebuilt. When I remove the driver and let windows auto find drivers, it finds a much newer driver. Steam says this is the proper driver, however now I get BSOD on a regular basis. I'm chalking it up to F-ing with the drivers so much.
I defrag, scandisk on a regular basis. I run Reg Cleaner, Spy Bot S&D and Norton Anti Virus as well.
