Received the laptop back from service centre, where I asked them to Fix for Event viewer error; Event ID 13, ACPI error and Event ID 37, Speed Of Processor X in Group 0 is being limited by System Firmware. They changed the whole motherboard for me and when i got back those errors are still there...and they told me it's safe to ignore it.
So I tried gaming with it but noticed everytime it Hard Freeze when i'm playing games like Path of Exile, Dota 2. The image on the screen was stuck as the last frame, mouse and keyboard no response, pressing caps lock doesn't lit the "caps lock light" either. The icon HDD light on the laptop is OFF, battery light on, power indicator light (light bulb icon) on. But for some weird reason the airplane mode light is ON. The fan is still spinning on Overboost though, but there's no sound at all. All I could do is to long-press the power button to hard restart it (Did try to wait for 30mins+ but still the same...).
And it produces a Event ID 41, Kernel-Power critical error everytime i did that (Did check ahead of time before the Kernel-Power error occurred to see what happened just before that, but there wasn't any log file in the event viewer before that). Tried all sorts of methods, mem test, chkdsk, sfc/scannow, windows troubleshooting, changing advanced power plan to max performance and turn off Hard disk sleep etc, updated bios, drivers but still cant fix it. Searched for ways online to generate an error log or something similar but seems that It only works if it's BSOD and you will get a dump file after that. For Hard Hang or Hard Freeze, apart from the useless Kernel-Power critical error, there's no way to pinpoint the source of the Freeze?
The hard freeze occurred randomly, ranging from 5mins after gaming and to 3hrs. I'd noticed that when i changed to intel graphic card to play say dota 2, it goes on 4hrs+ without freeze or hang (Is it because intel graphic card does not use as much power compared to Nvidia ones?). But the cases where it had hard freeze, all of them were when i'm using my Nvidia GPU to play games. The temperature of the nvidia GPU when the laptop freeze was around 70-80++ degrees C. CPU around 60-70++ degrees C. I'm totally baffled as why this happened because if the system overheats, wouldn't it be like auto restart? instead of Hard Hang? And also after the Hard Hang, the airplane mode light is lit, this totally weirds me out.
New laptop 2weeks+ old, sent to service centre for 5 days for a motherboard replacement. Did not Overclock or undervolt or stuffs. It couldn't be overheating issues right?
Programs that were on during gaming when then Hard Hang occurred, aside from Bitdefender and MBAM were:
6 Tabs of google chrome, speedfan, and of course STEAM.
Asus TUF Gaming FX504GM
i7-8750H 2.20Ghz
