Hello, I have just upgraded my motherboard and cpu from an old p166 to a p3 933. I was running Win 2000 which I had upgraded from win 98se with no problems. The machine was running good, just slow. After installing the board and processor it will not load win 2000. It starts up o.k., does the windows is starting thing but then goes to a blue screen that tells me; **STOP; 0X0000007B (Other numbers), Then it proceeds to say that I should check the drive for errors, yadda, yadda, yadda. So, I put in a fresh drive, loaded 2000 and it runs no problem. I can slave the old drive and see all the files etc. I then put the old board and processor back in and the old drive runs just fine. Please help, I have some older applications on there that I cannot replace. Also, I tried to reload 2000 and it will not let me. same blue screen except it is talking about the "kernel".
