'Battery Alert' appears before the 'press 'ESC' key for Start-up menu.', however, ' Cooling Fan Alert' appears after 'press 'ESC' key for Start-up menu.'

Thanks a lot,

You have other websites at which sellers can ship to Yemen. I know that Amazon.com, Newegg.com don't ship to Yemen.

Why have ignored my other points: Firstly, secondly, and finally?

Thirdly: If you wouldn't use eBay.com to purchase, then what else I can use if amazon.com, and others don't ship to Yemen.

If eBay is your only option then check the seller's feedback / approval rating for positive and negative reports.

Thanks a lot,

**Firstly:**the kind of thermal compound is silicon, it isn't sliver. 

The notes  written on the bottle of thermal compound are 'high conductivity, low bleed, Stable at high temperatures" in the properties of the silicone compound container.

@As long as the replacement fan mount to the board and heat sink properly. You need to be the judge on that. @ 

Secondly: You think that the new fan would solve the problem(system has detected a cooling fan is not operating properly) if I purchased it for $50.

I sometimes hear the old fan now installed sometimes make spin and blows air out, and sometimes no spin, and not air blown out while my computer is working. This is strange.

I have been looking for the whole fan/heatsink assembly.

Finally:

About in the ''CPU-Z' hardware Reading program, I see that the memory size of Intel internal GPU in  is "-1274" MBytes? This is strange size?

You said:

Could b that CPU-Z is not reading it properly, or that it is showing how much external memory is being used (-1274 is subtracted from your total memory).

If we follow you have said, then, the total memory size of the Discrete AMD GPU  '1GB'(1024 MBytes) - '1274' = - 250MBytes.

Where did '1274' come from? I only have an external AMD GPU with a total memory size of 1024MBytes.

Then there is no internal Intel GPU memory size at all even with hardware-reading programs?

Don't know why, here is a screen shot of my system and BIOS is displayed.

Secondly:

BIOS is the motherboard BIOS used to load the Windows OS.

Reference: https://en.wikipedia.org/wiki/BIOS 

If you look at my two screen shots, you will see that BIOS version is unknown while external AMD GPU is selected, however, it is known while internal Intel GPU is selected. So, why does this happen?
