Hello! How do you know that it's gone to the desktop screen?

Do you see anything when it boots up? Like options to go to bios?

i listen to window sound ,

Comptuer Starts But No Picture
 

Do you see any graphics when you first turn on the pc?

What language do you speak?

no i cant see any thing but hear sound of 7even .the problem is that i have a shop of computer hardware.that problem is dificult for me .becoz core i 5 is costly and i dont touch its main board.solve that ok

Don't worry about the board unless it's has onboard graphics.

Otherwise, try a different monitor. A different monitor cable and a different graphics card.

i chacked on several lcds and monitor but not work .not give signal to monitor .and give display on htmi cable .what i doooooooooo

Is it on board graphics? And are you getting graphics from the hdmi cable,yes or no?

yes i got .but how i solve on board graphics

If there is something wrong with the hardware then not much.

I would suggest trying without a hard drive.
There might be a problem with the drivers.
If it is on board graphics and there is something wrong with the bios then you may need to get an expert to fix it.

Try starting the pc with no hard drive in and try and get to the bios screen. You usually have to push F2.

Also check and replace the memory to see if that is causing the problem.

Just try and eliminate all other possibilities.
