The problem: My monitor displays the message "No signal" and gpu fans speed up a lot, this happens at the same time, as soon as monitor loses signal, fans speed up. It usually happens while gaming, but sometimes when I'm not, sometimes while booting, sometimes while browsing internet, it's random. Also the sound in the background works, so it's only the monitor that is shut down, turning it off and on doesn't work, unplugging it neither. The only way to fix the problem is to restart the PC, sometimes I have to turn it off (back side of PC case).
Additional problem: I know it's one post - one problem, but I still wanted to add that before this problem I had a problem where pc would restart randomly, so this still sometimes happens, especially during boot, but not so many times as the first problem.
Things I tried:
-cleaning the dust
-unplugging everything and plugging back, check contats
-checking temperature (it's normal, not more than 40 while idle and not more than 70 while gaming (gpu and CPU))
-malwarebytes (found something and deleted it, now it doesn't find anything)
-updated windows and geforce drivers
-running avast (couldn't complete full scan, because the monitor shut down after about 20% so I had to do a restart)
