I bought a new Ryzen 7 2700 and a ASUS Prime x370-PRO motherboard and a closed water cooling system from Corsair, but the computer fails to boot correctly.
All I get is a black screen, the monitor doesn't even get a signal. Tried the integrated HDMI port and the GPU port with both HDMI and DP.
The motherboard came without PC Speeker so I'm not able to hear any fail indication beeps.
All fans and LED's in the computer works fine tho. Tried the fan that was supplied with the CPU, it seem to run at a very slow speed when I power the computer on.
All cables from the PSU are correctly inserted. Tried different RAM and RAM-slots. Also tried another working GPU and PSU and reseting the CMOS but no luck.
From my experience with other computer builds, the CPU fan runs at 100% at boot but my supplied CPU fan runs at around 20%. Does that indicate on a known problem that could be fixed?
