Windows 7 Monitor screen goes black when switching user (No Signal) message

[Jaime]

Hi, guys

I currently have Windows 7 and am having a problem when attempting to switch users. I lock or log off from one account, click on switch user, and there is no signal. How do I resolve this issue?

Are you using these steps to switch one user account to another-

• press WINDOWS-L
• click "switch user" (wait 3-4 seconds)
• click on user icon
• type in password
• press enter (wait 2-3 seconds)

This procedure is not working. What else can I try?

Switching users seems to be an issue, not only on Win 7, but also Vista and XP.

Hey all, I got this problem resolved with a little help from the Microsoft support team -- I still think the dev team needs to release a patch... but:

1. Boot in safe mode, see if you can switch users without trouble (you 95% will be able to)
2. If safe mode user switching works, then you have a problem with a third party service.
3. Follow these steps to perform a clean boot and isolate some of the processes that might be troublesome:

Hope it works for you all too

Hope you get it running.
