there is a problem with my computer and it says it’s to do with my hard disk and i don’t know what to do, i’ve heard about disk clean up and i don’t how to use or where to get it or if i have got it? can anyone help me?

How do you wipe a pc clean?

I have a pc that is so crapped up with things, I just want it wiped clean like I bought it. A system restore to factory defaults doesn’t help the situation at all. Any ideas how to clean the computer and reinstall all operating systems and basic programs? (I have all of the orginal cd’s my laptop came with to reinstall)

I bought a used pc and wish to perform a clean install (format the hard drive) Would I need a boot cd or will it read the xp OP disk upon system boot? Also….a used computer is registered in someone elses name, can an op be reregistered into the current owners name?

i only have 40Gig hard drive capacity where i make 30:10 partition. driveC has 30 where i already utilized 85% of the spaced. although i always do disk clean-up, i still think that i do not get the enough clean-up. specially when i see scan files over 260000. are there any other way to reduce the system files. can we delete some files direct from the windows folder.
