I am not sure what problem I am having with my computer. I keep getting a blue screen with a message that says a problem was detected with my computer and that it is now doing a complete data dump. When I start my computer back up, sometimes Windows starts right up and sometimes I get a screen that says Volume C:// is dirty ad it starts checking file systems. After this is done, Windows starts right up and I have no problems for a day or two. Then again my computer will shut down and go to a blue screen saying that a problem was detected. I have tried system restore to previous dates, I have tried registry cleanup via cleanpc.com. I have McAfee Virus Protection. I am not sure what the problem is. Right before Christmas I tried to install a DVD Writer with Nero 7 Essentials ( I had originally installed this in 2008 and then uninstalled in 2008). This time during the installation I received a message saying Invalid Drive F://, and that there was a fatal error during the installation process. Thinking this was causing my computer problems I have tried to unistall Nero 7 Essentials with no luck. I keep getting the message: Invalid Drive F://. I am not sure what to do. At this point I am very frustrated. Please help.
