Hi everyone,

Full Black screen issues started occurring on my Asus TUF Gaming FX705DT (AMD Ryzen 7, Windows 10 Home, 64-bit, mfg 2019 after I replaced the fans due to grinding noise. The laptop boots fine, but shortly after logging in, the screen goes black intermittently.

I also noticed unusual fan speeds CPU fan reaches 4000 RPM GPU fan stays around 690 RPM The laptop heats up quickly to 74°C.
Could this issue be related to the fan installation, thermal paste application, or possibly another hardware problem? I’d appreciate any troubleshooting steps or suggestions to resolve this.

Thanks in advance for your help!
