Hello everyone,
I am working on an ASUS ROG G513QY laptop with RX 6800M dGPU.
Originally, this laptop was completely non-functional. I replaced the motherboard (part number 6050A3254002-MB-Axx), and with the replacement board it started working fine.
For a long time, the dGPU worked perfectly stable. I played several hundred hours on very demanding games such as Cyberpunk 2077 without any crashes, instability, or detection issues. Performance was excellent and there were no warning signs of failure.
However, after some time, the replacement motherboard...08-25-2025, 06:09 PM -

I have this machine. It powers up and gets fan spin, will even shut down when I hold the power button.

Do I have a potential dead CPU? or just a dead U1200? Not sure what to check since everything is powered up. -

Hello everyone.
I need help with my Yamaha MSR400 - Powered PA Speaker that I bought it used recently.
It is power on, and sounding good / working perfectly fine. However after 3 - 5 minutes, the heatsink is starting to get warm, and it smells burning a little bit.
I did tried multiple times on different day, event the speaker is not playing any song (input does not connect to any source, and the volume level is zero), after it turns ON, 5 minutes later, the heatsink is starting to get warm, and it smells burning a little bit. I am afraid keeping it ON longer than 5 minutes...
