"HDD not found"
Cannot boot the system
Dell's design is quite disgusting, you could only replace the memory from back panel but not HDD.
The HDD is directly fixed on motherboard. After I unmounted the HDD and connect it to my laptop. My laptop could not identify it, totally broken down. The customer said there is no sensitive data in that HDD, no need to do data recovery.
The rests is simple. Buy a brand new HDD, replace the broken one and install OS.

Overheating issue. Auto-reboot when playing 3D games.
CPU standby Temp = 70 C
When doing pressure testing, both CPU & GPU Temp > 99 C
2 or 3 seconds later, system frozen, no response and then reboot.
Because of the heat pipe radiator is embedded on motherboard, I must disassemble the machine.
Clean and reapply thermal grease.
