Is a hang on the logo screen common? I think there's a pattern to it but I can't quite figure it out.

Here's the symptom -

1. Go into bios with stock bios settings
2. Change settings to get your overclock
3. Save and load new settings
4. Loads new settings, boots into windows and works fine
5. Restart, hangs at logo screen
6. Another reset when stuck at logo screen and it loads fine

Anyone experience this? Just want to be sure it's part of the cycle and not unstable.
