Hey all I need some help. I have pulled out all my hair and about to lose it.... I have a water cooled rig I have put together and for the life of me having some sort of short that I cannot find. This is after going through the build at least 10 times. Here is the rig i7 2600k MSI Z68 GD80 16gb Corsair mem XFX 1250 Black Edition PSU XFX 3GB 7970 Black edition. Water cooling equipment: Swiftech Komodo full coverage block 2 x RX360 Rads Koolance RP-1000BK pump and res combo with fan controller 6 x 120mm Gental Typhoon 15 Fans Koolance CPU block So here is the problem. With the Komodo block installed on the 7970, no boot, power or anything. take the card out, boots (has onboard video) Run the card with the oem fan........boot Plugged three different lower grade cards in same slot........boot Take the block off and run the 7970 just by itself for a few second.........boot I have checked everything, and I mean everything in terms of connections. what am I missing that causes this not to boot when the gpu block is on. INSANITY !!!!!!!!!!!!
