I really love to help since Im too busy just jot down this basic and simple procedure. Although bisan ug medyo madugo ni but its the best thing to do if you are good hardware troubleshooter. Heres the first move. Remove 1 by 1 the pci slot card on your board but every time you remove each card Up your PC then shutdown if your PC still reboot then repeat the process until only the onboard Video/Audio is left. Worst comes to worst you need to Flsh your BIOS. Because it is possible that the virus resides on your BIOS. Lastly try borrowing Memory from any friend of yours and remove your memory and replace it with the one that comes from your friend.
