Unplug your other monitor and see if that helps, having monitors of varying refresh rates is known to cause issues.

There are a couple of things of note flagged up in Speccy but the most pressing issue is the weak PSU, which is rated as Tier F • Replace immediately here

The OP needs to get themselves a minimum of a 550W Gold efficiency rated PSU from the Corsair RM range, EVGA or Seasonic.

Do you have a “cheap” recommendation?

You have been advised as to what is required, we don`t do cheap only appropriate and you will need to get any prices local to you.
