Dear Sir,

Great videos on laptop repairs.

I have an ASUS ROG STRIX SCAR G533QS, after a Windows Update Reboot, Laptop Started to freeze at boot screen, after multiple restart it boots but then again freeze randomly.

Suspected SSD, replaced, same issues

Suspected RAM, Replaced, same issues

Suspected overheating, re pasted all CPU, GPU and Memory Chips.

Also cleaned all motherboard with iso propyl alcohol

Cleaned all Fans.

But same random freezes, but once it runs, it passes all My Asus Tests and Benchmarks successfully, no issues.

sometimes no boot problem is solved when power is not connected and Laptop turn on, on battery only.

Can you please advise a possible solution, sent to ASUS Repair center but they advise to replace the motherboard which is no 75% of the cost of a new laptop

I am an Electronics Tech myself but i need Laptop professional help to sort this out. Also i am keen to learn more about electronics boards troubleshooting.
