I have a Lenovo desktop which developed a fault, says there’s no operating system (and won’t let me reinstall anything); there’s now a continuous POST beep noise but no amount of troubleshooting is solving the issues. I’ve had the computer since 2012, so I guess it’s off to recycling it goes. I’ve owned and used a lot of computers over the years, this is easily the worst and I won’t be buying another one.
