Hello!!! ( Alas, I can't defrag drive C:\, 'cause there isn't enough free space. ) This could be your problem, no hard drive for system to work with. Get rid of all the stuff you can or get a bigger hard drive Also how much ram do you have, and your system is out of date ,SP3 ,ie 7, . and it looks like you have every anti virus program in the world with left over junk. Me thinks you will be better off reformatting and starting from scratch with a fresh install.
