i have purchased the msi kt3 ultra2 via kt333 chipset mother board.I have a amd athlon 1800+ xp processor and a geforce 4 ti 4200 graphics card.256mb of ddr 333.The computer starts up and says its to hot when it isn't even doing anything.The processor gets up to 50 degress c it has a 60 mil heatsink and fan and an exhaust fan blowing out the back.Constantly crashing.Its os is windows 98.Also my mother board did'nt come with a fan on the chipset.Any idea's?
