PC loses signal post-screen freeze and power off: Guidance required
Hello everyone, my name is Saahil Ansari. I own a gaming PC equipped with the following components: AMD Ryzen 5 3400G on an AMD Ryzen B450 Steel Legend motherboard, 16GB XPG RAM (8GB x 2 at 3200MHz), an RTX 3060 graphics card, and a Gigabyte P650B power supply rated at 650W. While playing Assassin's Creed, the display froze and the system shut down. After restarting, the PC started but my monitor displayed no signal, and neither did my keyboard nor mouse. Prior to these problems, I was using Windows 10, but upgraded to Windows 11. To switch, I enabled TPM 2.0 (I’m not sure what that does; I followed a tutorial on the Microsoft forum).
I’ve tried several troubleshooting steps: cleaned the RAM with an eraser and reinserted it, used my friend’s RAM, removed all components (RAM, GPU), cleaned everything, reinstalled hardware, and replaced the CMOS battery. Yesterday my PC booted up, so I attempted a downgrade to Windows 10. However, while making a bootable USB, the monitor blanked with “no signal.” After restarting, all fans—case, GPU, CPU—were spinning at full speed (I don’t understand).
Note: I can’t access the BIOS, safe boot, or any settings because my monitor isn’t responding. Please assist! Thank you.
Did you verify the HDMI or DP connection? Are there any warning indicators on your motherboard?
