My husband got a new PC at last
He was using a laptop which he bought in 2005. It was initially Windows XP, then upgraded to Windows7, then upgraded to Windows10.
He added RAM memory to 3GB, but the performance wasn't great any more for use on Windows10. I recommended an iMac to him, but he decided to get a windows desktop.
We went to Akihabara and ordered a custom-made PC: 32GB of RAM, 516GB SSD, and so on.
It came with a Japanese OS, so I helped him to change it into English and my IT job for that PC was done.
Now he is trying to hard to configure the PC and move the data from the old one. It will be at least a 3 month job, I expect.
