I just recently built a PC and everything seems to be working well, except this. Every time I shut down my PC and try to turn it back on again, it doesn't work. I have to disconnect the power from it and reconnect it before it will turn on. Restarting the computer, however, works perfectly fine (like for Windows Update).
Motherboard: Z87X-UD3H Intel 1150
CPU: i7 4770k (no OC)
HDD: WD Caviar Blue 1TB
SSD: Kingston SSDNow V300 Series 120GB
GPU: MSI R9 280x
PSU: Corsair RM750
I guess those are the only parts that could hold some relevance to this topic. If there are other parts that I should list, let me know, please. Thank you!
