But it's certainly possible for one to effect the OS in a way that your video would do some strange things. I suppose even mess up the video driver. My guess would be that the Video card or the driver had indeed gone bad and the Trojan is another matter that you dealt with.
While starting the computer, the BIOS, or whatever, looked completly blurred. There was no color, nothing, letters all smashed up. The computer wouldn't start up. I assumed it was a Video Card failure. I bought a new video card, and a virus scanner, just in case. The video card did the trick, but while using the Virus Scanner, it turns out that I had a Trogan Virus.
What Im asking is, can a Virus destory a Video Card?
