Purchased with windows 8 but took adventure of upgrade offer. Recently had failed visual display chip also clogged hdd which had become progerssively unstable and it eventually failed as a result of the trauma. Was advised by the stop I took it to be fixed...to upgrade ssd #as the original fitted only 8 gb). Then switched to ssd as main system and applications disk with hdd as slave (storage of personal files). Now the machine keeps dropping windows 10. Is this a result of the switch?
