Came across this board while trying to figure out if I have a virus. My screen will randomly go black and it just started yesterday. I have an Acer system running XP. I don't think is hardware related since my wife's laptop started the same thing yesterday. I'll leave that for another post. From reading your board I took the hijack this screen shoot of my system and was wondering if anybody could offer advice. Here's the file. Thanks in advance for any help you can offer.
