Why is my screen outputting strange characters and weird colours?

Hi everyone,

My 11 year old nephew was playing Minecraft, or was “downloading” it on PC when suddenly the screen went dark and showed “No Signal” even though the PC was still running. We couldn’t bring it back so we reset the PC, and then it got worse. All letters, numbers or symbols were somehow destroyed, even before Windows had started.

It was like when old NES games suddenly crash. And in Windows it was also like that, only not in 8-bit color. I’ve already tried resetting BIOS by removing the battery, but it didn’t work. Please tell me it’s not what I think it is…

Thanks in Advance

P.S: My sister’s PC has Panda antivirus on it.
