Hi, rather annoying problem here. Really looking to find out if my drives are faulty or its the motherboard. I have two Seagate and one Hitachi SATA drives in my PC. Only Two SATA drives are ever attached at one time. One of the SATA drives has the OS installed, and the other two have data. Recently one of the data SATA drives causes a BSOD everytime Windows boots up. If i attach the other data SATA drive it is fine. The BSOD error message refers to IRQ NOT LESS OR EQUAL etc and the file mentioned is viamraid.sys. So yesterday i decided to take the two supposedly good SATA drives and set them up on RAID 0. All installed eventually and it was running like a dream. When i turned on the PC this morning the PC doesn't even pick up any of the SATA drives at all. I can't access the RAID setp as it freezes at this point. From this information what could you suggest the problem would be? Thanks for reading. Darren

I'd be checking the bios to make sure raid/sata is enabled etc. You loaded the sata drivers from floppy at installation(F6)? Tt Lanfire MSI K8N Diamond AMD64 3000+'Venice' 1gb pc4400 OCZ Powerstream 520w 6600GT WDCaviar 160gb sata x2 ;~}

Hi, thanks. The raid is definately enabled in the BIOS and yes i loaded the SATA drivers when prompted during the installtion of WinXP. Have just purchased another mobo, as it seems more likely that one motherboard has gone bad rather than three drives. Will i have egg on my face later, we will see. Many thanks again, all the best Darren
