Hi guys,
I am experiencing an issue when I boot my computer it takes multiple attempts before it fully starts up. All the fans, hard drives and LEDs light up but it shuts right off after about 1-2 seconds. It repeats this anywhere between 1-5 times before it boots.
When it boots it it works perfectly fine, I've run a stress test for ~1 hour with intel XTU and no issues.
CPU temps run @ 26 degrees c idle and 66 degrees c under load (from XTU stress test)
The motherboard has 2 EPS 8pin plugs on the top of the motherboard, my PSU only has 1.
Through all the research so far, most people are saying the second is not required.
I am using:
CPU: i7 7700k
MB: Asus ROG Maximus ix Apex (Bios 1010, just updated)
RAM: 2x 8gb Mushkin blackline ram
GPU: Gigabyte radeon r9 290
Antec high current gamer 750w
Asus PCE-Ac68 PCIE wifi card
PSU and GPU are from my previous build, PSU is about 5 years old and GPU is about 3 years old, the only new components are the ram, mb and cpu.
I've tried updating the bios, clearing cmos, booting with nothing plugged in except the essentials (ssd, keyboard, mouse and monitor).
Any ideas or suggestions would be greatly appreciated. Thanks!
