Hard to say, but it might either be a fried Motherboard or a dead Power Supply.

If when you press the power button you hear aboslutely nothing, maybe just a light flicker, then it's probably the Power Supply, which will need to be replaced.

If you hear a fan start up and maybe a beep but no BIOS, then it's the motherboard or the BIOS was damaged.

This is of course speculation.

The easiest to test is the Power supply, buy a new one, put it in, if nothing happens, return it, hopefully you can get your money back or store credit.

There is problem with your graphic card, remove it and try.

may be your integrated video card is dead.

See if your monitor plug pins are OK.

Just put the new card you get into the PCI-e slot and then disable the integrated graphics in your computers bios.

This issue can be caused by any of the below possibilities.

-Monitor is not on

-Computer is asleep

-Connections not connected properly.

-Monitor settings are not correct.

-No Post.

-Hardware issue.
