got dell inspiron desktop with amd64live with windows vista and in the last two weeks its been very slow from turning it on to switching off!
i have checked for virus, spyware etc but nothing showed up after various scans, am using McAfee security centre and windows live one care,
i have also removed all apps and programs installed from just before it slowed down but this had no effect

anyone got any ideas what could have suddenly nobbled my pc? it used to be much faster!
oh and admins if this is in wrong place feel free to move it
