My system has been randomly crashing since I swapped out my asus p4p800 deluxe mobo, for an asus p4p800 E-deluxe mobo. I've run memtest86 with no errors, done viruschecks, reseated all pci/agp cards to no avail. I've posted the minidump files here last month and all I was told was that it's a hardware related problem. I did swap out my Radeon 9800XT for a Geforce 6800 GT last month, and I got the same errors with both cards. In the last week alone I've got the following crash errors: -BAD_POOL_CALLER -DRIVER IRQL NOT LESS OR EQUAL -PAGE FAULT IN NONPAGED AREA -nv4_mini.sys -nv4_disp -Ntfs.sys - Address F76C5126 base at F7690000, DateStamp 41107eea I do have two soundcards in the system as well, the Audiophile2496 and the EMU 0404, do you think it may have something to do the cards? I had both in the old mobo with no crashes so what could be the cause?
