My PC runs Vista SP2. It boots up fine but when you click on a user (either an administrator or limited user) you get to the welcome screen and then nothing happens. Pressing ctrl alt delete twice gives you the task manager and then it is possible to cancel and then everything works ok after that.
I have run a virus check and also for spyware.
Please can you suggest a possible cause or what I need to look for.
FIrst thing to do. Reboot the computer and tap f8 to enter safe mode. If you can enter there. Go to start-run -type on msconfig. Then turn off all startup items and apply then close and reboot the computer. If allows you in then something in startup is the problem. A hung program is the possible cause.
THanks> I have tried re-installing the virus checker and the firewall but it made no difference.
When in safe mode, nothing seems to load at all. When in diagnostic mode I have selected all services and all start-up programmes not to install and the problem happens. The problem is I do not know what the difference is between these two modes except that the firewall and anti-virus do not appear to load in safe mode but they do load in diagnostic mode. So I am not sure I can add any programmes to get from one to the other?
Sorry I didn't make it clear what I meant. When I am in safe mode the computer starts up correctly. When I am in normal mode with all programmes and services selected NOT to start then I get the problem. So it is the movement away from safe mode that is "causing" the problem.
