This morning, my pc still working completely fine. But until this evening, when i come back, it won't turn on anymore, when i hit the power button, nothing happen, even the motherboard led light won't come on, too. Only the led from the avexir ram heatsink comes on , blinking.
Here is my pc specs:
Core i5 6600k
msi z170a krait gaming MB
16gb of ram single stick
PSU: Seasonic snow silent 750w.
GTX 1060 gaming X 6gb.
I think the psu should be enough to power on my system, cuz in the last 9 months, everything works perfectly fine, even when i run furmark, aida64 stress test, until this evening. Now , my pc won't on, i literally cannot do anything.
