SiS is common on many Intel motherboards (like the nForce by Nvidia is on AMD motherboards). Basically, "Silicon Integrated Systems" puts chipsets and occasionally integrated graphics chipsets on a motherboard. Either his integrated graphics are horrible (I doubt that they could be that bad), he has messed up BIOS (I also highly doubt), or he has poor drivers or none at all.
I think he's missing drivers, or has a very old version. The SiS 650 integrated graphics chipset is about 3-4 years old now. If he hasn't ever updated the drivers, he really should. I had one on my old computer. Man did it suck!
