I have a Dell something or other PC, too lazy to look up the model number. And for the past couple weeks it has been screwed up BADLY. Whenever I boot I always get this message that says "Winlogon.exe encountered a problem and has been shutdown", and shortly after my computer gets this blue screen that says system has been shutdown, or failed, or something, and I have to push the button to turn off my computer. IT IS DRIVING ME NUTS! I ran Mcafee and it found a couple viruses, ran Adware and it found a bunch of stuff, ran spyware SND and it found some stuff, AND I have the Mcafee Firewall running, what's going on? I'm guessing it's something with the winlogon thing, but I don't know how to fix it. I just bought this computer a few months back, so it's really irritating.
