Hello. I just built a new pc. The parts are:
Ryzen 5 2600
g skill trident z 16 gb 3000mhz
tomahawk max b450
msi gaming x gtx 1660 6gb
Monitor: dell alienware aw2518hf
I built this 1 week ago and had no problems. Yesterday I started my pc my monitor said no hdmi signal but my pc was turned on I just could see anything. I tried different ports on my monitor, plug the cable from the graphics card again but no luck. I pressed the reset button on my case and then it opened normally.
Now today I opened my pc again and the same problem happened. I had to restart the pc for the monitor to work.
What might be the problem ?
