Hello Guys. My latest Computer which I built about 4 weeks ago is playing up. It is the first time I have used Sata drives and my first RAID setup. My chipset is 945P, I have two WD 3.0 250gb Hard drives set up as RAID 0. I have Wndows with SP2. Anyway here's what it is doing. Most times I start it up it will not boot, I get a black screen asking me to select proper boot drive. I have tried loads of different 'boot orders' but it is still unpredictable so I will keep trying by turning it off and on and it will boot eventually. The thing is, Sometimes when the computer is on and I am doing something it will crash and go to that same screen. The other problem I have is I am getting an alert from my task bar that says an Error has occurred in my RAID volume and I should backup immediately. If I click on the icon it will take me to the "intel matrix storage console" where it will state that my volume on Port 1 has an error. What I'd like to know is if the two problems I am having are related and if the 'error' on Port 1 is a physical error within that HD or I can just format and start again. Any help is appreciated and I am happy to answer any questions. Chhers.
