Good spec PC is sometimes very, very slow

TomS12345 · April 28

I have a PC that I built a few months ago. It has decent specs (I'll list them below), but sometimes (and it's doing it more regularly now), it just slows right down. I don't quite know how to describe it really. Put it this way, it can run No Mans Sky and various AI models quite fine, but when it does its thing, I can't even open the start menu without waiting for more than a few minutes. The PC basically becomes unusable.

It start going slow at eighter just like that, while I'm using the PC, or (and this happens more regularly, maybe 65%-80% of the time) when I wake the PC up from sleep.

When I do manage to open the task manger, I see that resource use is usual. There doesn't seem to be any difference between the PC running normally and when it's slow.

There doesn't seem to be any apps that crash during the slowness. The PC just slows down.

When it slows down, I'm almost always forced to do a forced restart. It then usually takes multiple minutes (today at least 10-20 minutes) to start up. It stays stuck on the motherboard loading screen for a long time.

Also, just to point it out, from what I can remember, there has been no blue screens of death while the PC is slow like this.
