Hi there. I bought this refurbished from an online company. Ever since the first week or so it's been unbelievably slow. It takes an age to turn on and then when the desktop has loaded it can take something 5 mins+ just to open a browser or any apps. Sometimes it then works fine, but sometimes even just switching between apps or tabs on a browser can take forever. I don't have loads of apps or tabs open, hardly anything saved on the laptop and only a handful of apps. It's 8GB RAM and core 1.5 8th gen so nothing obvious for it to not be working well. Any ideas would be super appreciated! Thanks, Tim
