Hi, 

 

I am a little concerned with my new PC as I have only just built it yesterday. Out of the many systems I have built I have never experienced this problem. 

So what happens is i press my power button it will spin everything up and all the lights come on etc then it shuts down then boots properly. Any Ideas. All parts are brand new. 

I do get the Asus code A0 when it has booted into windows, this code means all is well apparently. 

 

Specs: 

I7 8086K 

Asus Maximus x hero 

16GB Corsair Vengeance Ram 3000Mhz (Using XMP)

Be quiet dark rock pro 4  

Be quiet fans 140mm fans

EVGA GTX 1080 TI SC Black edition SLI only running one card (ATM)  

500GB Samsung 850 EVO 

500GB Samsung 860 EVO 

250GB Samsung 970 EVO 

Seasonic Focus Plus Gold 1000W

Bitfenix Custom cables

 

I am hoping its not a faulty Part.

If it happens only during the first ever boot, it's nothing to be worried about as it's most likely the board just making BIOS adjustments on first startup.

Wasn't on first startup. 

 

It keeps doing it if I unplug my psu cable 

 

Only once though.

Hi, 

 

I have hopefully found the solution. 

Having XMP enabled made my system unstable. 

I will monitor it over the next few days but hopefully that was causing the issue
