mmb - used to get exactly what you are describing for weeks and weeks. If you have not made any other radical changes to the system, first try reseating all memory first then if you have more than 1 module, take one out and run with the other(s) until you find the culprit, turned out that one of my modules was bad - I just changed both and now no more BSODs. Used to drive me crazy !! Worth a try.
