Upon closer inspection i noticed that only the cpu fan was tuning down and up and sounds like the pc is restarting over and over
I'll get another video with sound included
Also im not sure but this motherboard has some kind of smart fan stop feature as displayed on the website i linked. Could that be the reason its doing that?
I have this motherboard
I have tried clearing cmos, i have no speaker in the motherboard and i would assume normal pc usb speakers wont work in this case
Demonstration video
here is a link to a video i recorded where you can see the fan slowing down and speedin up again. I recommend to watch the entire video
I have used this computer for only a month so i dont believe that to be the reason the thermal paste is about 3 weeks old and with the other psu it did the same thing, also i tested ram and its still doing it, i uninstalled the gpu and still does it
I have a working 450 watt psu but all worked fine until yesterday i dont think the system uses even 400 watts tho
Edit
It also does the same thing with a different psu
I cannot disable the setting because i cannot access bios it doesnt boot
After noticing something weird i shut down every other noice in the room and listened closesly to the computer, it seems that when its on and the fans reach the normal speed it sounds like they stop and after they slow down...
Corsair 650 Watt 80 PLUS White Certified PSU about 4-5 years old gpu is 2019 cpu and motherboard i bought a month ago ram is 2019 i believe montior is 6 months old all in perfect condition as far as i can tell the system worked completely fine until yesterday when i enabled Secure Boot
So I needed to enable Secure boot, beacuse with Windows 11 Riot's Vanguard Anti-Cheat requires you to have it on in order to play Valorant. I did that and after I had saved and exited BIOS there was no display on any of my monitors after my PC restarted. Screen turns on for a few seconds...
