So I`ve vad this prebuilt system for almost 2 months and until today it worked perfectly, I started my PC today and it said displayport no signal, I was like what? Yesterday it worked all normal and now it doesn't work. I looked at the GPU fans and I saw that when I start the PC the fans start spinning and after like 3 seconds they stop. The problem is I can't access anything on my PC because my monitor say I have no signal. I really don't know what to do and I would really appreciate some help.
