I got this computer about 3 weeks ago from Dell. Having goofed up installing some programs and perhaps eliminating others as well as perhaps making some bad choices in adjustments this question; can I format the drive 'C', which has the OS, and reinstall the OS and going back, so to speak, square? And, just for future reference, when I'm asked to insert the "Dell Remote Access Disk".....where is it? I have looked. Where is "PC RESTORE"? Thanks
