They will instantly snatch control from you. Then will sicken your high-end PC by overflowing the RAM & overwhelming the processor. And you will see your computer groaning till it crashes. Believe me, viruses were never so lovely before.
Computer is a very complex machine. You just have to break one support to crash the whole structure. It can be done in many ways- overloading the processor, overflowing the RAM, flooding the hard-disk, occupying input/output system or any other resource, and erasing essential software (like- operating system). Follow the Disaster Level for getting a categorical view of the project.
