I have a Toshiba satellite pro C850-1HD intel core i5 3230M 2.6GHz 8GB ram 64 bit with windows 7 bought only in June 2013. It has suddenly started running extremely slowly, taking 20 minutes to start up, and all programs take a long time to open, including outlook. I have antivirus software eset nod32, have tried defragmenting my disc, windows defender, have tried startup repair, run ccleaner, run malwarebytes. I tried system restore but it failed - unknown error.
I would appreciate any advice, as I work from this computer and do not know what to try next.
