I have been having system problems as of late. Every time on the first boot of the day, the computer crashes and appears to turn on and off repeatedly (lights in the computer flash on and off). This may also randomly happen when the computer is left idle for a couple of minutes. What could the problem possibly be?
The system is only a few months old.
R5 1600 oc to 3.9 GHz
Rx 570 4g
Corsair vs650 80+ white power supply
Also the problem occurs even when I have changed the power cable, whether the system is plugged into the wall or the UPS.
 
Solution
Probably that cheap PSU. Review by Tomshardware says it has problems if there is a high load on 12v and low on 5v. Definitely not a power supply for overclocking.
