I want to start by saying I know very little about computers. I can use them, but just don't know all the technical stuff. That said, I have a desktop, which I have had for 5 or 6 years now. A few days ago when I turned it on, it said my disk needed to be checked for consistency. I let it do its thing and then after it was done it went to a black screen that said Bad_Pool_Caller and a bunch of other stuff. It said it was dumping my physical memory to disk and counted to 99 before returning to the original screen (where it checked my disk for consistency again). I allowed it to cycle nonstop through those 2 screens for over half a day. I tried pressing F8 and switching to safe mode but all that does is change the black screen to blue and it continues to cycle just the same. The page with the error message says to remove newly installed hardware but there has not been anything installed for months and even if I had installed anything... I can't access my computer at all with it cycling between those 2 screens constantly! I am getting very frustrated, can anybody help me?
