Computer boots but no display abd no sound

[dominic1018]

I recently installed an antivirus(avira is)in my pc then tried to check my system for viruses. After that my pc started to act weird so i restarted it then there's a note saying that there was an error. I didn't know what to do so i just turned it off hoping that it'd be okay.when i turned it on there was still an output which lets me fix the errors. I forgot what option i chose but after that my pc was no longer giving display and sounds.

I tried to use another monitor. Switch the ram. Nothing happened.

I need your help. Thank you.

Can you boot into safe mode?

Do you hear any beeps during start up attempts?

Start by opening the case and reseating the Graphics card, RAM, etc. and otherwise checking all connections and cables. You may have accidentally knocked something loose. May look okay but is only partially connected.

What version of Windows are you using? Where did you get the Avira software? May have been the source/cause of the original error.

Thank you for your answer.

I can't boot into safe mode cause theres no display on the monitor.

Monitor, vga cord and power cord are all working.
No beeps.

Im using windows 8.1.

By the way. Is it possible that the vga female port of my video card is damaged? I see an error message that says "no input signal".

 

[Ralston18]

Yes. That is possible.

Try another known working video vga cable if you have one - it might have a different "fit" and work. Or, otherwise, show that the problem is most likely not the video vga cable.

Then try the built in video/display port on your motherboard.
