Hi. I'm trying to install a Sata Seagate Barracuda 200Gb but my PC will only power up for a second or two then it powers down. If I put my IDE back without the Sata it's fine. I've tried them together, with same power down result, and with everything out bar the Sata - still only a second of power. OS: WinXP Mobo: MSI K8N CPU: Athlon 64 3200 My psu is a basic 300w, but I would have thought that wouldn't be a problem, when only the Sata is attached? So I'm assuming (hoping) that isn't the issue. I'd greatly appreciate any advice. Thanks in advance. Peter.
