alright, when i start up my computer, the welcome screen comes up, but then an error-message like window pops up with no text, just a red X icon and an ok button. i've got my computer set to automatically log on, for convenience reasons, but after the error message pops up, it says saving your settings like its logging off... i can boot in safe mode with no problems, but NOT in safe mode with networking support, i get the same error if i try that. any suggestions?
