Have a computer that I was told all of a sudden had all sorts of Virus
warnings. Would try to boot in safe mode and it would come up and
then shut down. Now when I try to start it absolutely nothing
happens. Hear the power go on but don't see any of the BIOS
messages? Am confused if this could actually be a disk drive
problem? Shouldn't I be able to at least see the BIOS come up no
matter what could be wrong with the disk drive? Could a virus infect
a motherboard per se? Thanks for any tips.

No and yes. There's a virus (an old one) that went after the BIOS --
even made a few boards with duplicate BIOS chips if not jumpers to
lock out BIOS access -- however, odds you have that particular virus
are miniscule to nonexistent. You've some troubleshooting to do.
Completely disconnect and re-PWR, possibly jumper MB and its BIOS back
to defaults. Similar to an overclocked lockup, some MBs provide a
boot hot-key provision for getting back to defaults. If the same
problems after getting a boot, could be problematic hardware issue or
possibly then a virus. I'm not really a virus person past that -
running limited web interfaces, conservative use of programs, and
regular HD rewrites from binary image backups. Plenty others that
would be, though.

I would lean more towards a defective PSU. It has nothing to do with your
virus issues, but 'most' startup issues are PSU related. Virii rarely
destroy hardware. You may have been rebooting many times in a row and the
PSU just decided to give up the ghost.......:-)

No, Disconnect all peripherals and unplug all pc cards and try it again.
If it works, connect a cd/dvd rom and try to boot up a bootable cd.
If it don't work check power supply or motherboard.
If it does boot a cd, then add one peripheral at a time and insert one
pc card at a time until it fails again. When it fails, the last thing
you plugged in is bad.
The solution is to
1. Purchase a new motherboard because virus has affected the BIOS of
your PC(http://click.linksynergy.com/fs-bin/click?
id=x1ijFJ9Dvfc&offerid=102327.10000056&type=4&subi d=0).
2. Make your harddisk slave in another PC to enable you to retrive
your files before you format your C: partion or before you format your
hard disk.
4. Then remove your hard disk from the PC and change it back to master
and insert it back into your computer.
5. Install your operating system e.g. Windows XP Unlimited for windows
operating software.

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.
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.
