System fails to reach the 'American megatrends' interface.
Your grandfather's computer keeps showing the BIOS boot screen even after powering it on, and you've already changed the CMOS battery. I don't know the reason for this issue. The system still loads into BIOS settings, but if you need more information, let me know. Your CPU is an Intel i5 6400, with an iGPU, and 8 GB of DDR4 2600 RAM.
Check for multiple RAM modules and remove one to determine if problems continue. Verify if any additional devices like a printer, webcam, or scanner are connected. Disconnect those if needed to isolate the issue.
