I have a Dell Optiplex GX280 running Windows XP that doesn`t do anything after start page is loaded except turn off or restart. I can ONLY (won`t allow me to do it in normal mode) do a system restore in safe mode & then it works perfect. When I turnoff or restart it goes back to the same problem - freezes up after start page has loaded. I have to do system restore in safe mode only all over again. What a viscous circle! Any suggestions to fix this? I do not have any Dell system retore or Windows XP CD`s - I bought it used. Let`s pretend I`m an idiot at computers (which is not far from the truth)so any help in plain easy instructions would be greatly appreciated.
