Didnt know where to post this. Just wanted to say thanx to all for tryin to fix my computer shut down problem. Towards the end she would only run long enough to start windows then black out. Put a new power supply in it and she even seems to run faster than before. hasnt shut down in over a week now. Thanks again for all the info. Your all great people.

thats great it is running again, sounds like it was a failing power supply and it was failing the POST test.
