I have an AsRock K7S41GX motherboard about 1 yr old. Recently, I turned the system on (XP - Pro w/AMD Athlon 333/266 768Mb RAM, 80Gb HD) and received no POST or anything else (well, the fan on the chip did run). I attempted to run the hard drive on another working computer but got nothing but a white line at the bottom of the screen. If I slave the drive I can read it. My question is do I need another motherboard AND hard drive or just one or the other?
