awsum140, I was using GPU Temp, but I'll install GPU-Z and check it out. In the comments people where mentioning about the Lenovo Legend Y530, that is that it will suddenly freeze up. One commended they thought it was a Windows problem and not the machine. I also agree. I've experienced this too, but it only happens when the 16GB of RAM is full. I am not doing anything that should eat up 16GB of memory, so I must have a memory leak. I'll check it out.
It locks up for about 5 minutes (mouse pointer doesn't move either) and then comes back with like 4GB of memory in use. I suspect that Intel Optane 16GB might be causing the freezing up. I'll look into this too and I can toggle it off and see if it happens anymore, plus plug that leak.
I have another used computer (only a few months old) coming today. It's a HP Pavilion X360-15 inch. This too has 16GB of Intel Optane memory, but only 4GB of RAM and see if that one does it too. It only has a i3 processor and uses Intel integrated graphics. I am hoping it will be fast enough for things like browsing, email, and watching movies.
