I reformatted my computer like a year ago, and i want to reformatted again and i forgot how u do it. I’ve currently reformatted my computer using the operating system CD, when i did that, i found a lot of things missing, like the sound. I’ve look through all my CDs and found Drivers and Utilities Cd that says reinstalling Device Driver and using diagnostics, utilities and online documentation and another one that also says Drivers and Utilities but it said reinstalling conexant 56K Data/Fax Modem Software for Microsoft Window. Do I insert one of them when i reformat my computer?
