This is a Toshiba Satellite C650 laptop that has had a history of issues with updates. Last year some updates began to fail and we could not get them to apply successfully. Other issues occurred, bsod without warning, etc. Finally in Nov/December I did the factory reset and then re-applied all of the updates successfully. Things seemed to be working ok after that. After a month or so the laptop was then out of the country and offline for around 4 months. Shortly after coming back online it began to have issues with some updates, until now when it will not even successfully check for new updates. Also occasionally blue screens again. Also, if you select View update history, it says "you have not tried to install any updates for your computer"
We use ESET Nod32 antivirus and it hasn't reported any virus/malware issues.
