Hello everyone. I have a Intel(R) Core(TM)2 Duo CPU E8400 @ 3.00GHz processor on a P5Q Premium motherboard . I have 8gb of (2048 MB PC2-6400 DDR2-SDRAM Corsair CM2X2048-8500C5D *4). I have Windows 7 ultimate installed and my main boot disk is a brand new Samsung HD103Sj - 1tb drive. I also have three other HDDs in the system. I have beed getting the BSOD off and on until today when I got it 6-8 times. I managed 6 dumps of today andt am attaching all the which I have. Memtest I have run several times and shows OK. Bios has been upgraded. Chkdsk /f has been run on the boot disk. Could someone please advice what the problem could be. This is a fairly new system and any advice would really help me from spending more money where it is not needed. Thanks for all help.
