Re: 2017 iMac freezes up
Multicore Benchmark on my laptop: ~3000
This is really good for a refurbished laptop that I paid $89 for.
Multicore Benchmark on my old iMac: ~5000
The latest $150 Amazon tablet also benchmarks at this. It is an amazing world we live in.
I still use this machine to analyze chess games and openings. Because the display tends to quit, I access the machine remotely.
Multicore Benchmark on my new iMac: ~8100
Ideally I would have built a new AMD machine and gotten up to 20000. However, I needed a Mac to do the work that I am now doing.
I am suspicious of the combo drive using an SSD as a buffer to the hard drive. If something went wrong there then it would definitely freeze the computer.
Best wishes,

2017 iMac freezes up
A few months ago I purchased a used 2017 iMac and installed Windows 10 on it. For the most part, this has been a great machine. However, there is now a problem. The computer will appear to run slow and then eventually freeze. This usually happens while using Google Chrome.
I am normally good at dealing with any kind of software problem that comes up, but this could be something going wrong with the hardware, like the RAM, the SSD, or some controller board. Hardware is mostly outside my area of expertise, although I did buy some new RAM chips that I have not yet installed. I could try taking out the old RAM chips and put in the new RAM chips and see if the problem persists.
On the software side maybe there is a virus, which seems unlikely because I have Norton which normally takes care of these things. It is possible there is a driver issue, but that also seems unlikely. I would not expect Google Chrome to be the problem, but I would not rule it out either. I could try a different web browser.
I need to reboot the computer into McIntosh mode and see if the problem happens again. If it does, then it is a hardware problem. However, if the problem goes away, then something is wrong in the Windows 10 world and I would consider erasing the Windows 10 partition and reinstalling the operating system, which is a time-consuming task.

I'm impressed with the benchmarks. We are seeing a bunch of low-end devices with powerful processors.
