Hi, i am almost completly updating my compter from a p2 to a sempron 2500+. I am getting new mobo, processor,ram case,ect everything except for a hard drive. I am running win 98 on it right know and when i am getting my new parts i will still be running 98. I just wanna know how i can completly clear my hdd like it was just bought. also does it erase those errors that come up on the blue sceen after a incorrect shut down.
