I've had my PC for about two years, never had any problems.

Since yesterday, suddenly my monitor switches off every time I try to start a game. Just the monitor.. the pc stays switched on. Power button and restart button doesn't work that time. I have to restart it by turning off the main switch.

I tried to peek inside the case and when the monitor switches off, there's nothing visibly wrong going on. The fans are still turning.


My specs are:
Ryzen 5 2600
MSI B450M Mortar Max
Ram 8+8 GB 3200MHz
Thermaltake Litepower 550Watt




Thanks!

If there's video evidence the computer is still running, try another display (tv) or display cable.

If display is turning off because of something more serious, it could be driver or psu related. I would suspect the latter being that the psu unit isn't very good even when new and lucky it lasted this long without issue.

I meant record gaming video using xbox dvr in win10 to see if it's still recording giving an indication if system is still running.

Seeing as mouse/keyboard are turning off, looks like psu related.
