Well my overclock went sour the other day so running on stock settings. I've been trying various FSB's which I'll go into once I've fixed this problem. I think I've knackered my windows install (well that's what it's telling me) so I've booted into my Windows disk however it's just a black screen. I've left it 15 minutes and just a black screen. This is all at stock and I've tried it multiple times. What's left to do?
