I am not sure where to post this so i posted this on this Misc. Forum And i am hoping someone would help me :( Weeks ago, I want to make another account for my little sister because she was doing annoying stuff like downloading some unknown softwares and installed it, changing my account details, etc. Then an idea came to my mind to make Another Account with non-Admin Privilege. After making the new account, I logged out, then log in on the new account. Then the problem comes, The screen became black and in several seconds it flashes with the normal login screen then turned black again. Then i shutdown to my computer and log in to the new account. Nothing is wrong and everything is normal, then I log out and login on the Administrator account and the same problem happens again. Looks like i can't login to other account after i logged to an account. What should i do to fix it? Please help me, Thanks :D

I would try making another new account -- it sounds like that one is corrupted. The first time you ever login to it, it may take some time. Don't do anything such as shutting down or hitting ctrl-alt-delete. give it time to create the new profile. If this was helpful, please vote by clicking the green triangle.

Of course i have @_@ Even by clicking Switch User on the Computer Locked Menu ( Windows + L ) induces this problem D: I've tried making around 3 users D:

It could be a video driver, especially if it must reset or change resolution, DPI, or even enable/disable Aero for the loading account. When this happens, does the video eventually return? I'd say check for updates, although this may just be a normal operation of your particular video card or driver. Although checking for updates is good anyway.
