First of all, I have the full version of avg8 anti-virus.

I booted up in safe mode and it has the same problem. Not sure if the problem is clear, but just for the doubts I'll say it again. When I turn on my computer, everything is fine. I get to the User Account logon screen, I log into my account, it starts to load, but nothing shows up but a black desktop and a window of My Documents....

That happens in safe mode as well, I noticed that on a normal boot, once I log into my account, I look at the processes running and explorer.exe is one of them, yet I need to start a New Task running explorer again to get the taskbar and desktop and apps to work...

Should I do a Hijackthis log?

Or perhaps it could be fixed if I could tell the computer to run [b]explorer.exe[b] each time it logs into my account? if it can be done... just an idea.
