PC Suddenly Freezing Periodically Every 2-3 Seconds


Having some major issues with my Windows 10 PC out of the blue. Suddenly it has started becoming unresponsive periodically for very brief moments, non-stop, every 2 to 3 seconds. For example, when moving the mouse across the screen, it will very briefly stop every couple of seconds and then jump across. I can't think of anything that I've done or anything that has changed that might have caused this, but it's making the PC borderline unusable. I can't play games without freezing, I can't watch videos without freezing, I can't even scroll with the mouse properly without it freezing and then jumping across the screen!

Any help would be hugely appreciated.

Some more details please.

Make and model? Have you backed up your files? A reset could be on the cards here.

It's custom built from Dino PC in the UK. Around 4 years old.

Not backed up yet but if no other solution is possible then I suppose I will have no other choice but to reinstall Windows!

Another thing I've noticed is that my disk usage seems to be constantly at 100%, at least when I first start the PC, and that is with a very limited amount of start up programs.

Check out Bob's answer first.

But have you kept up with the canned air and replacing thermal paste?

Let me share a recent investigation.
