OC'd Booting of Vista / WinPE 2.0 media

[papashex]

Odd problem with cd/dvd boot media. As mentioned in the title, this system is an overclocked C2D e6600. It can currently boot from any cd/dvd store bought or home made media that is not based on WinPE 2.0 without issue.

When I attempt to boot WinPE 2.0 based media the first text mode progress bar for "loading files" completes. When the graphical progress bar comes up the system may tick off a couple of marks on the bar, but it will hang before moving on to the next screen.

If I remove the overclock the media will boot ok. What is WinPE 2.0 doing that is different?

Pretty standard parts in use.
