Highly unlikely that flashing the bios will cure the problems described. Flashing the bios can be risky even if you do have have the monitor and keyboard working an NO you cannot do it without them. Try working on the symptoms you mention first. Remove everything installed on the MB except the CPU and one dimm, disconnect all drives, unplug all external peripherals (keyboard, mouse, etc) then attempt to POST, If it does POST without errors then add keyboard and mouse to enter BIOS.

I did everythin you have mentioned. I even checked by connecting it to TV. Both monitor and keyboard working with TV. Still same no power issue with CPU and TV..

I even checked Cmos and long press power button which google showed. And also replaced with new cmos battery. But No luck.
My friends uncle was a computer repair person and he told about this bios reprogrammed or update. He is currently out of city for a week..

Good idea testing your KB and monitor. To flash the bios the board needs to POST (power on self test) it is possible the BIOS is corrupt, This board supports Q-Flash which you could try - instructions are here https://www.gigabyte.com/MicroSite/121/flashbios_qflash.pdf . It that does not work then it's either a partially failed power supply (which can be tested with a multimeter instructions here - https://www.lifewire.com/how-to-manually-test-a-power-supply-with-a-multimeter-2626158 or with an inexpensive ATX power supply tester. Could also be a CPU failure (unlikely) or the motherboard may have failed.

It's good your friends uncle has offered some assistance

If you need a manual for the board go here: https://www.gigabyte.com/Motherboard/GA-B85M-D3H-rev-10-11#support-manual

on your mb is a power good led. is it on or blinking. if it blinking you have a power supply issue. i would try a test power supply first. if there no post. from another pc download the newest bios file. google award and ami bios recovery. rename the bios to ami recovery also leave a copy of the bios unchanged. put it in the root of a flash drive. power up and leave the pc anlone. if the bios is working it should recover in 20 min or so.
