My home pc has decided to fuck up bigtime, its fine if i actually get onto windows but if i shut it down i just get a black screen withsafe mode ,last good configuration etc but none of them work and it just keeps rebooting.

Iturn off auto restart and i then get the blue screen with an error code
DRIVER_IRQL_NOT_LESS_OR_EQUAL and a 0x error code.

Ive formatted the pc with the recovery discs which was a nightmare as the recovery kept stopping but after a day of trying got it to format and it was okay for a day then the same again .

IM on xp media centre and any help with this much appreciated as everywhere i ring up tells me its something different and i cant turn my pc off at the mo as it takes me hours to get windows to work again .
