Need some help. This is my 5th system build so I thought I knew what I was doing. Anyway, this is a completely new system, Ausu Rampage 2 M/B 3 x 5870 in 3 way crossfire, Intel I7-975, 12Gb Corsair DDR3 12800/1600 (all new in a Xaser water cooled case) Thermaltake 1500W toughpower psu - My last system was water cooled so know what im doing there. The problem is that as soon as i hit the satrt button it flashes blue, fans spin and then everything stops. The M/B stays lit up and I can clear CMOS, but cannot restart the pc. Have checked the power button connectors to the psu to make sure they were right way around - still no luck. nay suggestions?
