Just crashed and Im gettin sick of this. When its crashes I get a full blue screen with no text on it. Just checked event viewer and theres shedloads of these, which upon looking at the times seem to be the source of the crashes. The disc in question is a samsung spinpoint SP2504C. Its a SATAII drive and the mobo im using is an epox EP9NPA+Ultra Ive just had a quick look about on the samsung site and cannot for the life of me find their diagnostic tool. Can anyone help ?
