i resantly reinstalled windows, now i'm running in to major problems, my computer thinks it a 2400+ athlon even though it's a 2100+ athlon, nearly every item i in stall says it's corrupt including windows sp2, and software that use to work just fine, the only thing i can think of is the system drivers are encorect but the other ones i tried made it think it was a 1500+ i'm don't even think thats the problem, also manny programs freaquantly error and shut down, exspecialy internet explorer, and the computer restart ocasionaly, i reinstalled window twice and sure it not a virus, think somthing to do with drivers thanks adam

mainboard msi k7n420 pro, 2100+ athlon,
