My 10 year old 17" G73JW shuts down without any error messages after approximately two minutes. It's not an OS issue as it turns off even while in the ASUS BIOS page... meaning no OS running. (Hardware failure) It does the same even after I remove the SSD and leave it without boot media. I have also removed and swapped the memory sticks around and boot it with the two SIMMs minimum. I just finished repasting the CPU and GPU with Artic Silver 5 Thermal Paste and swapped the hard-to-reach memory SIMM, but the issue continues. I hear the GPU fan go on before it turns off, but can't tell if the CPU fan is turning on. But... at just two minutes from a cold start, I doubt that the processing units are overheating, specially after the repasting. Something is telling it to shutdown after a specific time, but I can't figure out what or why?
I'm starting to think that there's something wrong with the motherboard, but before I spend my money, I'd like to know if anyone here has any other ideas as to what might be causing this issue. Also, does anyone know of a reputable place where I can buy a G73JW motherboard. I found some without CPU or GPU boards and wonder... what if the GPU or CPU are the source of the problem?... If it still fails, can I return the motherboard?
Anyway, I love my G73JW, but I already spent four days trying to fix it. Out of frustration, I was about to pull the trigger on a 2021 ASUS ROG Strix G17, but it is SOLD OUT or backordered everywhere I looked. If anyone can point me to where I can purchased this very "affordable" ROG gaming laptop now, please post the link. In the meantime, I will continue to try to fix my G73 and wait for the Strix G17 to be available... whatever comes first.
EDIT: Forgot to mention that my friend has a G73JH and I tested my G73JW using his AC adapter... no dice.
