Edit: It is the floppy going haywire. I found out the stick that was giving me the BSODs because it would blue screen me almost immediately every time. I have had a number of BSODs recently and so I ran MemTest and I got 3 errors on Test 3 and a whopping 290 on Test 5. I have had Crucial Ballistix PC3200 in a 4x512 configuration for over a year and a half. Last night I began testing each stick individually. Stick one passed with no problem with three sticks to test. Since it was late I went to bed. Resumed this morning with stick two in the same #1 slot. When it got to just where MemTest kicks in the screen started to read out in sequential order over and over the following: AX:0212 BX:1A00 CX:0001 DX:0100 @X:8000 MemTest never loaded; I never got to the screen. Even when I popped out the MemTest (floppy) in continued to do this. The same for the other remaining sticks as well. I though I was screwed by doing something unknown to my system when changing out sticks. So decided to try something and reboot with the third untested stick (but getting the same sequential readouts) and without MemTest inserted it booted just fine. I have not a clue as to why this happened or what it means. I have run MemTest before so I am not a novice but I sure could use some experienced help here. Why didn't MemTest load? What is going on with the readouts? What does it mean and what are your suggestions? Thanks.
