Sudden Blue Screen and Logout

[tazmanians]

I am having logout problem when I do Photoshop, the screen suddenly goes into blue screen and then it will come into login screen, When I enter my password I can only see a fresh desktop its like restarted...

I thought this may be an issue when turning auto switching to graphic mode.... but its the same when I turn off auto switching graphic mode. This happens several time when I am working.... so I cant do any design work continuesly.

Does anyone know how to solv this problem ?

The problem is that either the loginwindow process or the WindowServer process is crashing. Look for crash logs for either of these processes. They may give information on why they're crashing. Look at other logs, like system.log or kernel.log. They may give information on what's crashing and why.

It could be a bad graphics card. It could be buggy graphics drivers. It could be bad RAM. It could be a bad OS install. It could be some third-party haxie you've installed. It could be any number of things.
