Hi Dark Mantis, please find below text referred to
On first attempt at boot the fans started spinning (case, heatsink, graphics) and the power cut off after 2 seconds, after that power got cycled again (loop). The phase lights on the mobo at this stage were green, green, yellow, red. I've removed the graphics card and booted again and this time it did not cut off. However no beeps coming from motherboard just phase lights continuously on in the same configuration.
I've tried removing components (RAM, HDD, DVD) and booting just with the mobo, CPU and PSU, and same thing happens. There are no shorts (I've pulled the mobo out and tested it on a piece of cardboard) that are obvious and I have tested the PSU with a multimeter and everything seems to be in tolerance levels. The speaker is connected to the mobo in the right configuration but I haven't heard single squeak from it even with the memory removed which would suggest motherboard problem
PSU is 400watt (Z400-08FC
Mem is 2 x 2gb DDR3 1333Mhz
CPU i3-540
Regards
Mike
