I have an iwill kk266 kt133a mobo and a t bird 800 processor and 256 meg of hi density pc133 RAM. when itry to overclock it and im unsuccessful, ie: it hangs in DOS and i have to shut down. It takes about 5-10 minutes for me to be able to boot back up again. my haqrd drives wont spin up and my video card wont come on if i try to boot up and earlier. Does anyone else have that problem if so is it normal? help me please.
