ASUS F515 (11th Gen Intel) Laptop Blue Screen Error

I purchased the ASUS Notebook F515EA model and encountered a blue screen error. After consulting with Amazon, they assured me that a replacement would be possible if the ASUS authorized service provided a signed and stamped malfunction report. Armed with this information, I sent the PC for service.

Despite explicitly mentioning the issue, I was informed that the repair had been completed. We agreed. However, upon receiving the product after the supposed repair (mainboard replacement, setup, and testing), I discovered that the problem persisted. What struck me as odd was that the product reached ASUS at 11:00 AM, and the authorized service claimed to have completed the mentioned procedures and returned it by 5:00 PM on the same day.

It's evident that these processes couldn't be executed so swiftly. Is it possible that the ASUS headquarters, along with the authorized service claiming to replace the mainboard and installing Windows 11, are unjustly extracting money from you? If the mainboard was indeed replaced and the issue persists, three possibilities arise:

It wasn't replaced, and only Windows 11 was installed before returning.
It was replaced, but a faulty board (despite being new) was installed.
The old mainboard was reinstalled. There is no other explanation for this situation.
My written notes seem to be disregarded, and the procedures appear to be incorrectly executed. Additionally, attempting to contact the headquarters proves impossible. It's a deceptive ordeal, and I regret dealing with ASUS.
