The solution is to
1. Purchase a new motherboard because virus has affected the BIOS of
your PC
Don't be silly. *IF* it was an actual virus in the BIOS chip,
all you need is to reprogram the BIOS chip. And you can do that
at badflash.com . (Notice how I provide the link, with no affiliate code!)
The only requirement, is that the BIOS chip be sitting in a socket,
and be removable. Really old boards use DIP (dual inline) EEPROMs,
while more modern boards use PLCC square chips sitting in a socket.
The very latest boards use eight pin SPI chips with serial programming
interface, and as a rule, those are soldered on. So a board with SPI will
be harder to resurrect.
There is a picture here of how to remove a dual inline DIP EEPROM.

This is a socketed PLCC. With a sharp tool, you can pry up on the
diagonal corners of the chip, to ease it out of the socket. There
are also proper removal tools for doing the job.

Radio Shack sells a chip puller for PLCC chips. It hooks underneath
the diagonal corners of the chip, and allows you to pull upwards.

With either chip, you want to make special notes on the orientation
marks on the chip. On some of the PLCC products I've worked on,
the socket has a triangle to mark pin 1, and the chip may have a
tiny dot stamped in it, to mark pin 1. When removing the PLCC,
note how the dot and triangle line up. The new chip has to go
back precisely the same way.
In a posting some time ago, someone purchased a motherboard used
from somewhere. They plugged in the motherboard, and noticed two
strange glows coming from the BIOS chip. The glow was caused by
the VCC and GND pins on the chip being burned off
The dopey
guys that sold the motherboard, put the BIOS chip in backwards.
And with the symptoms from the OP so far, it is not at all certain
what the problem is. It is too soon to do anything.
