Computer Blank Screen After Logon

My computer is having this weird problem where when I finish logging in, the desktop would just be purely blank. The mouse cursor does show up and i can control it, but none of the normal desktop things would show up (wallpaper, taskbar, icons...). If I hold down the power button and force shutdown, and then go into the safe mode when i start up, all would be normal (except for the wallpaper of course due to the safe mode). If i restart from there i would be able to get my desktop back. However if i reboot the problem comes back.

Also, the computer lags significantly when the desktop is gone since the task manager usually goes to "not responding" state.

Is there a way i can fix this problem? Restore point would not be an option since the problem started about two years ago when it was not very serious. I tried to locate the problem but explorer.exe and dwm.exe are both there...

Please help!!!!
