System stability

[TheWikipediaPwnzJ00]

I recently purchased a ga 8n sli and my sytem is suffering crashes up the wahzoo. With my previous asus board, I could literaly run my system for days. Every component is the same except for my 7900gt, which was upgraded from a 7600gt. My psu is fine because it is an antec 550 watt neo he. Other than the motherboard, what constitute a reason for system crashes. These crashes happen sporadically ranging from 2 minutes to 2 days within a boot. I currently don't have a floppy drive, but if I go to my local B&M and buy a floppy drive to flash my bios, how likely is it that the latest bios solve my stability problems? The latest bios for my motherboard is version 5 and it was version 3 out of the box.

BIOS upgrades do resolve stability problems.
I would use the latest BIOS anyway.
Give it a try.
