I can play for hours in a heavy game and its a silent system, no crashes ever. So it cannot be overheating or a loose connector as it would crash once it boots into an OS. If I then switch off the PSU and restart, it works 100% of the time. Then I press the power button and it going into BIOS - but not full BIOS, just the Gigabyte header at the top and then reboots again, and again and again. Then select shutdown from either OS, the machine powers off correctly.
#Clover efi shutdown after boot mac osx#
Currently its power switch is only plugged into the Power front header, no reset plugged in.īasically when I boot from cold (previous full power off), it boots to Clover 100% of the time and then to either Windows 10 or Mac OSX 10.2 Sierra perfectly. In rebuilding the PC I decided the old Mini-ITX case was too tight so I purchased the Fractal Design R4. I was using the system and then the PSU failed quite dramatically, so I purchased this new EVGA PSU and plugged it in with the expectation that it would fail dramatically either the motherboard or CPU were possibly fried - but no, it booted fine. I had a 100% working system with all of the above components except the case (new) and PSU (new). Once it boots into Windows10 or MacOSX (Hackintosh) it is 100% rock solid even when Geekbench stress tests or Intel CPU stress tests with temperatures never going above 45 degrees C.Ĭooling: Corsair H100i V2 using USB on internal header However if I power OFF the power supply at the mains / or the switch on the PSU and THEN reboot using the front switch it ALWAYS boots correctly. Sometimes the duration after the reboot is 1 second, sometimes its 5 seconds (and inbetween). Symptom: PC reboots itself to BIOS title screen and then powers off, reboots itself and repeats. Hi, hopefully someone has the expertise to solve this really puzzling problem.
