Hello.
I recenty changed my mobo for a asrock z370 killer sli. (I had gigabyte z370P D3) i was overclocking the cpu to 5ghz it was holding up for a week (on my old mobo) and than it started crashing. I lowered clock to 4.7 and it ran for a week and than i had to lower it again. Than i was running at 4.5 when i asked why this is happening and they told me ( community of this site) that i have the poor power for my cpu. Soo i bought this new board and rebuilt the computer and when i turned it on it started, but the screen didnt even turned on, my keyboard mouse and headphones didnt light too and my computer restarted on its own like every 10-15 sec.
My specs:
GPU: Nvidia geforce GTX 1080ti Founders edition
CPU: Intel core i5 8600k 5.0Ghz (liquidcooled)
RAM: 2x4gb Corsair DDR4 3000mhz
SSD1: 500gb Crucial CT500mx
SSD2: 240gb Kingston SUV400S37240G
MOBO: GIGABYTE Z370P D3(old one)
PSU: Corsair 650M
OS: Windows 10 Home 64bit
Please help me fix this problem just write something pkease i need support.
