Computer reboots (Force shut down "Black screen instantly and) once a day then after 1-5 seconds, it turns back on, as if nothing happened, didnt prompt me to safe mode before running, (Windows 10). No matter how much CPU load it could shut down (Reading PDF files to gaming 100% load). Noticed about a month after purchase (a year ago)

Checked Temp during 100% load of CPU,GPU,HDD via "Heavy load" app 61'c max cpu 65 gpu and 70 TEMP1(idk which one this is)(SpeedFan app)
Check minidump log
Tried apps such as "WhoCrashed"
Tried disabling restart on system settings,
Full system scan,
Have just replaced PSU (Happened before the old PSU as well ((Generic 700+watt to 350 80+))
Only have 1 RAM piece (4GB)
2 Hard disk drives (2x1TB)
GT730
amd a-8 7600 (Quad)
A quite tight low tower
ASUS A68 hm-k

What could cause such reboots??
***Thing is at reboot i hear a static like sound on my headset, as if sound had have a electric like pulse.***
