flashing from sleep mode

HP Recommended

My HP DESKTOP-FDPAHOO works fine if I do a 'cold' start, but when the unit goes into sleep mode, it has an intermittent display problem on waking. Sometimes when it wakes, the screen just flashes different colors (e.g. red, white, blue, green, etc.), and nothing I do can break through this flashing multi-color display except turning it off via the power button for a hard shutdown. The computer won't recognize any input from the mouse or keyboard during the flashing display. When I power it up again, it boots up normally and works well.

i recently re installed widows 10 thats when the issue started.
