hangs on "windows xp is starting up"

[NeptuneUK]

just before it shows the user names, pc just hangs... until i restart. its very annoying. the only time i ever had this before is when i did stupidly high overclocks. but im running stock speeds.

the PC works fine when i restart it. its after the loading bar. it briefly says windows is starting up on the blue background before it shows the user names. of course it hangs on it instead of loading... restart.. works ?? sometimes it even gets to the username icons then freezes so i cant click the names.

in both cases i can move the mouse pointer.
