Hi all. I am running Vista Home Premium in a Dell Dimension Desktop which is about 6 months old.

Right from the beginning, we have only ever had one user name to log into the pc.

Out of the blue after not having anyother problems before , today , I tried to log in and got the message

"The user Profile Service service failed the logon. User Profile cannot be loaded"

I have tried to look up on this to sort it out , but all of the solutions involve logging in under a different admin name - but we do not have one.

The other solution method I have found is to press F8 when he computer boots up - but this doesn't take me to any menus on my computer. My options are to press F2 For Setup Menu and F12 for Boot Menu

F2 takes me to a bios screen , and F12 gives me the following options :

Normal
Bootable Hard Drive
On-board CDROM Drive
System Setup
Hard Drive Diagnostics
Boot To Utility Partition


I thought there might be a way for me to do what I need to do by booting in cmd prompt or msdos? But I cannot find a way to boot into it. I can't even find a way to go into safe mode ( assuming I could get into safe mode? )
Can somebody please help me.

Many thanks
