I think I got a motherboard problem. I got a AMD Athlon 2400+ with a A7N8X mobo. With a PCI RAID Addon Card, with 2 SATA 120gb HD on raid 0. Well one day it says it can't find my OS. So I am like ok. So I pop in Windows CD, Load RAID drivers and it can't find it. So I install windows on my IDE HD. Try to install all drivers, none seem to work. Video card doesnt work, Raid Card doesn't. It only detects 256mb or RAM when i got 2 sticks of 512 in there. I think I have done everything Possible including shutting off power and removing Mobo Battery. Anyone else think it can be any other problem besides Mobo?
