I need some help with my computer as it has being rebooting with the blue screen almost every day since I changed the MoBo (Asus Commando) and installed Vista Business. I think that is a hardware driver (or software?) since it doesn't happens in Safe Mode and some of the error messages say something about ataport.sys. I disabled the auto reboot mode to read the blue screen and I have written to errors: 0x0000007E (with the ataport.sys description) and another one was 0x0000008E. I run MemTest x86 v3.3 and passed fine.
