Replaced ASUS M2N32 SLI deluxe wireless motherboard and 600watt Enermax Power supply in a 2006 Velocity Micro Vision (custom build from BestBuy website). I was told they were both dead after one year and one month. Also replaced, AMD 64 x2 3800+ processor for an AMD 64 x2 6000. When I start the computer I get a blank screen. While the power is on, if I unplug the 12v cpu power from motherboard and plug back in, the pc starts normally. I tried numerous BIOS settings with no luck. Does anyone know what’s going on?
