I've had this Toshiba 4025CDT since '98. It's running W98, with 64Mg of RAM, and an 80Mg HD. Its now overloaded with junk, and is freezing & crashing. I'd like to strip it clean, start fresh with only a few programs. Would someone outline a simple process for reformatting? I really like this machine, and don't want to boneyard it yet. Plain language please, folks...I'm probably a 4 (out of 10) when it comes to PC knowledge. Thank you.
