Thanks a lot,
My questions are unending, but I hope you find a little more time to answer me:
Desktops do not have an integrated card on the motherboard, they are either integrated into the CPU like your laptop or the use the older style AGP or newer PCIe slots.
Thanks a lot,
Firstly::
No, I have Desktop Computer(Intel P 4, 512MB of RAM(DDR), and Graphics Card with 256MB of RAM)
My P 4 has a motherboard integrated Graphics Card(onboard(Internal) VGA), Audio Card, and Network adapter. The motherboard manufacturer is Asrock(775i65G(REV: G/A 2.12), and AGP slot to which a removable graphics card can be installed, and so you can upgrade.


Secondly:
The amount of memory for the internal GPU is set in the BIOS.
There is no memory amount for the internal GPU set in the BIOS at all.There is only: Processor Type: Intel (R) Core(TM) i5-2410M. CPU@2.30GHz.
Thirdly: I know that the manufacturer of discrete GPU integrated into motherboard is AMD. But, What is the manufacturer of internal GPU integrated into CPU?
Intel, You must set the BIOS to disable the internal/Intel GPU and just use the HD6770.
Thirdly:
Although there is no option at all in my BIOS to set internal/Intel GPU to disable, I would like you to let me know:::
1- Why must I set that? If I had set that, then I could be no longer able to switch between graphics 'power-saving GPU, which is Intel GPU, and high-performance GPU, which is 'discrete GPU/HD6770.
2- I can switch between graphics (IGUP) and (DGPU) without seeing Switchable Graphics Mode in my BIOS
I am nearly sure that there is no option to set the Intel GPU to disable in my BIOS. I have tried that before(could you please take some time to look at my points below).
I can switch between two graphics 'Intel graphics and ATI Radeon Graphics', although the ' that option 'switchable graphics mode' found in the third screen shot below is not seen in my BIOS at all.
In this screen shot below, Intel graphics is only active.
In this screen shot below, ATI Radeon graphics is only active.
But I didn't find any striking difference between when integrated GPU is only active and when the Discrete (dGPU) is only active. Thus, why should I choose one other than the other?
What do I get?
As long as I can switch between two graphics without seeing this switchable graphics mode in my BIOS, I think that I don't need to update the BIOS to enable switchable graphics mode

Yes, I really couldn't find any option to 'Selecting a Switchable Graphics Method, Dynamic Scheme or Fixed Scheme. Is it because switchable graphics mode is not seen in my BIOS?
As discussed in the article, that switching between two graphics needs to update the BIOS until seeing Switchable Graphics Mode in BIOS. However, I have not updated the BIOS, but I can switch graphics (IGUP) and (DGPU) without seeing Switchable Graphics Mode in BIOS.
Besieds, I really have updated my BIOS from version: F.05 into F.1B, but the switachable Graphics mode in this screen shot above wasn't found at all. Also, there is no Intel Smart Tecnology in BIOS as it there in the screen shot above. I don't know why.
My GUPs are AMD Radeon and Intel graphics
Finally:
Finally: You didn't comment on the screen shot of the speedfan utility. Have you seen that my fan working well or not?
Can't tell from Speed Fan as only the GPU is listed. Read the following:

Then what benefit is there from Speed fan utility?
