Hello, I recently acquired a Toshiba satellite c855d was running windows 7 was having issues so i factory restored from memory then took advantage of last minute upgrade to windows 10, worked ok for a while, i added more memory, didn't seem to help.
computer seems at times to take a long time to load pages, then locks up for 10 - 30 seconds, sometimes minutes, then works for a second and locks up again, sometimes it works for hours with no problem then starts acting up again.
not sure if have even posted this question in the right place
any ideas would be greatly appreciated
thanks
