Hello!!
So i have very strange problem. I just bought BRAND NEW PC COMPONENTS for build up.
When i turn on pc it starts to run normally and after 1-2 mins it suddenly crashes and reboots by itself and keeps doing this thing over and over again. CANT GET INTO BIOS, because pc doesnt recognize any monitor (tried with gpu hdmi+dvi and mobo hdmi+dvi).

Here is a list all of the things i have done allready trying to find out what is causing this prob.

-checked ram in other pc and it runs perfectly fine
-tried every ram slot
-tried with other psu
-changed thermal paste for cpu second time
- booted with gpu and without gpu
-reset cmos battery for 30 seconds out of the motherboard
-rebuilt every component again to mobo
- every cable etc triplechecked

Maybe my motherboard broke during buildup? No idea, but i hope you guys can help me with this.

Specs:
CPU : i5-9600k
Motherboard : Asrock z390 pro4
Gpu : 1060 dual oc 6gb
Ram: hyperx fury 8gb
Ssd: kingston 250gb
 
Solution
You can't know, but I've literally Never had a bad cpu sent to me in 15 years of building rigs. I'd always suspect the motherboard first.
