Hi,
I really need help, purchased a intel core duo 2 e6400 processor, some gigabyte lga 775 motherboard and 1gb ram from scan.co.uk
I have tried 2 different PSU's 400w and 600w, the RAM and gfx cards in a different machine and they all work fine. However I get this problem:
Whenever i connected just the 12x2 molax power cable to the motherboard the gfx card fan and cpu fan spin fine but nothing boots up, then I realised i need to put the ATX 12v 2x2 power cable in too, when i put this in the cpu fan and gfx fan both spin, then stop then spin etc as if the motherboard is switching on and off. there is no display obviously, i hav shortted the CMOS, reset the battery etc and i sent the cpu,mobo,ram back to scan and they tested it and said its all working fine! Am i doing something wrong? the 2x2 ATX 12v supply near the CPU seems to be the problem. What could be causing it to swtich on and off considering have tested everything else except the mobo and cpu in a different machine?
