Hey everyone, I made a mistake by turning on the ultimate power mode in my newly built PC. After applying the setting and restarting, the PC booted up but displayed nothing on the screen. In my attempt to fix it, I removed the CMOS and put it back, and even took out a stick of RAM but later reinserted it. Now, the PC turns on but shuts off after about 30 seconds. I'm really worried that I may have damaged something. What could have been affected here, and do you think I'll need to replace any parts? Any help would be appreciated!

No worries, you didn't mess things up too badly! Those troubleshooting steps are pretty standard. I'd recommend clearing the CMOS again, but this time try using the jumper method while the PC is unplugged. Also, it might help to re-seat both RAM sticks and ensure all power connections are snug. You might have accidental dislodged something when you were working inside the case.
What exactly is this ultimate power mode? Just curious. Also, make sure you’re clearing the CMOS the right way. Check your motherboard manual for specific instructions since different models might have unique steps. Usually, it's just about cutting the power and removing the battery.
