hi, been givian a laptop running Vista that when booting up stays on a black screen after windows scroll screen with an open window(again just black) but has LogonUI.exe message..been trying to system restore and was trying to get some utilites to run like combofix etc but nothing seems to fix it as yet. Tried a few different boot cds but no luck..if I try to get to the LogonUI.exe and just delete it will windows just replace it with new version..
tried all Repair My Computer etc..

Just thinking might as well format it to Win 7 but would like to see if the error could be fixed first..if only out of curiosity..

any ideas please?
