First things first: update your computer. Security fixes and fixes for
other problems come out all the time.

What Debian version are you running?

On what sort of computer?

Do you have screensavers or similar kicking in?

is there a temperature issue?

Are there logs?

A little more information would be helpful.

All the very best, as ever,
