Predator Laptop screen keep blinking also making weird static noises

Predator Model: Acer Predator Helios 300 PH317-52 After I replaced my Predator's AC Charger, my screen has been blinking/having black screens at times while gaming. My laptop also does weird static metronome noises before/while my screen monitor blinks. The backlit keyboard also blinks for some reason, I feel like this issue with my laptop has something to do with my power supply. I had another issue before which involved my charger not working, could be my fault because I kept the wire behind the laptop's fans which could have heated up the things inside. I charge my laptop with an extension not directly through a power socket, I really need help on this one.

Does the problem occur when using the laptop on battery only? Also, can you provide the exact model of the laptop? Example PH315-52-58VH. Can you send some pictures of the old power adapter and the new power adapter?

I'm currently testing if the issue occurs on my extra power adapter, I'll try to test run it on battery

My Acer Care Support app only shows it as Predator PH317-52, it is a 2018 Model with the red theme.

Blazingrino well some stactic noise its completely normal on all electric devices sometimes comes from the capacitors sometimes even from the ssd drive chips the blinking and black screen its not normal are u sure you replaced your adapter with another with the same exact specs amps/volts etc check with a voltmeter if you can if the adapter you have now its outputting the correct voltage to power the laptop good luck

So I tried charging with my back-up adapter. Also this time I charged my Predator directly through a wall socket, there is no difference and the issue still occurs. Blinking monitor and keyboard with static noises. I'll borrow a voltmeter some time

Blazingrino if youre still under warranty would be probably a good idea to contact acer support also if youre able to check your battery wear with hwinfo or battery bar pro and try a battery power drain followed by a bios setup defaults

Unfortunately, my Predator's warranty has already expired. I have tried out the hwinfo software and it shows that my laptop battery has a wear level of 21.1%, does this mean anything bad?

I suggest you try to calibrate the battery:

If wear and tear still remains at 21.1%, you should purchase a new battery.

By "weird static metronome noises", I mean the noise coming through my earphones/headphones everytime I play a game like CSGO and StarCraft 2.
