hi .. im no wizz kid .. by that i mean im not a pro in pcs but i thought your hard drives look a little full as well.
Talking of disk de fragg .. i tried that & my pc took 3 hrs & my prob did not go away. I copied most of the stuff fron C drive & did a format & re-install .. i know it aint "as" quick but saved me loads of time trying to sort it out. .. This internet is a timebomb! Most of the gremlins seem to creep in from the net. I tried spyware & had antivirus / firewall running but got well n trully clobbered last July! The program from the net got thru my firewall & installed before i could blink an eye.
(probably due to broadband connection being faster)
Then the cheeky program presented me with virus warnings !!! can u believe it! .. i couldnt get rid of it .. the pc was virtually locked up!
... so i re-installed everything. Thats not what id call good way to do business.
Anyhow good luck russ
