Problems, where to start. Screen goes blank so I have to restart it, unit freezes up so again have to shut it down and restart, unit will not shut down by activating the off switch so here again have to unplug the power cord, looking at one program and unit switches to another but suspect that is windows 10 fault. Talking to customer service people that I have a hard time understanding and spending literally hours on the phone trying to fix problems that seem to repeat regularity oh and for stickfight, I'm 82 so it seems stupid to invest a lot of money on something that will probably outlast me. All I want is a dependable unit and if there is a problem I can get the customer service I need. I have listed just a few of the problems I have had with this unit
I would take it to a well rated "local" PC repair shop. I have one (husband/wife) here that is reasonable in cost and very competent.
Take EdM advice. Most shops will trouble shoot problems for free or a minimal cost. It could be a faulty memory module or even the power supply. I get the age thing as I am 71. I still rum Win7 don't trust Win10 especially the updates. I am even trying to learn Linux Mint to try to ditch Windows altogether.
