Computer problems?

I've had this problem for a long time, it was gone for a while but now I have it again.

Whenever I start the PC, the screen is frozen for a period of 5 seconds to 10 minutes, then after a few seconds the screen goes out and there's "no signal" but the PC is still running and you can also hear the background noise (Netflix, yt what I was just watching) then I turn the PC off completely, even if I turn it on again it's the same again and after turning it on and off a few times it'll work… I just don't know what to do next, I can't ask anyone can help me there

sorry for spelling or anything else

Sounds like the graphics driver is causing problems. Have you tried another version?

Vga or HDMI cable?

Other version?

Hdmi

Amd rx graphics cards?

What kind of monitor do you have and what kind of graphics card?

If you can't find a better way, you could reset the entire PC. With Windows there's also a function to keep the saved files. To do this, simply go to Settings> Search bar: "Reset this PC"> Let's go and then you should get an option to save. I have never done that before, so please watch a video or something and be careful!

I have a hannspree monitor graphics card that I don't know exactly because it is from my brother, but there's strix on the side and asus directcu II on top

Well, with monitor problems, the first thing you should check is the cable and the connections on the monitor / graphics card or mainboard.

see if the cable is loose
try another cable
try other connections if available

Driver version.
