Hi, I forgot my password to BIOS and I wanted to reset the settings. I ONLY remove the battery for 2 minutes/insert back and after this operation I can’t boot. All fans spinning fast but screen are black. Before computer works fine, without problems.
I know that I should clear RTC using the jumpers but I didn’t do it 🙁 How can I now fix this issue ?
So far I unplugged all cables from mobo, try boot without cmos baterry, remove battery for 30min
– no effect…

Do you get video during the POST at start up? If not, try a different video connection if one is available?
As mick has pointed out, you may have damaged the board if you did not unplug the computer prior to removing the battery. You also need to practice proper static discharge procedures.
You also stated you removed the cables from the board. Are you sure they are now connected correctly?
You could test the board by booting with ONLY the following connected.
CPU/Hsink/fan, 1 stick of RAM, power supply to motherboard connections, monitor to board and keyboard. NO case to board connections, add in cards, drives of any kind, no external hardware other than the aforementioned. You do need a sound device, which should be integrated on the motherboard.
You start the board by shorting the two power switch pins momentarily with screwdriver or other. You should get a post up to an onscreen message indicating there is no bootable device. If that doesn’t happen then try removing the stick of RAM and rebooting. You should then get an audible error.
