Windows 7 - Windows keeps logging me off!

I have no idea why but every now and then (pretty often) Windows will just randomly log me off and then i can just log in and keep going but it is very annoying..

It mostly happens when i am playing a full screen game (of any kind) and i press either the windows key to minimize it or i press alt-tab to minimize or if i just close the game and it goes back to the desktop..

So basically if i go from a full screen game back to the rest of the computer it logs me off and at various other times

Any suggestions/help? I would greatly appreciate it

Just in case.. I have windows 7 64 bit on a Dell xps laptop

Enter viewer in your search box and open up event viewer..go to Windows Logs/Applications and look for any critical errors ... take a screenshot and post it as an attachment to your next post..

I went to where you said and i wasnt sure if there was any critical errors or not but there was a ton of logs.. what should i do next?

Thanks for the help by the way

Critical errors are marked with a red circle with a white exclamation point... this is what we need to see if there are any...

Mmk i went back and looked for errors and i must have at least a couple hundred picture attached
Any ideas?

Your problems seem to stem from MSQLserverExpress... are you hosting your own website??

Nope, i do have Microsoft Visual 2010 beta though and i have made a website in there but i havent hosted it from my comp..

Im not doing anything out of the ordinary and nothing that i dont normally do
