oh no..no POST

[Welshman666]

appologize if this is wrong section to post,

however i just basically finished my second watercooling project and was to start up my PC to test it however Im not getting a post..

what is happening when i click the ''on'' switch on my PSU the blue LED light up on my EVGA 780i in the top right corner...i then click the power button on my motherboard itself and the RAM cooler fans spin for half a second but the pc wont start up..

at the same time an orange LED comes on near the blue one

i get a flash (like for half a second) of red LED on my GPU

and the motherboard post indicator thing (dunno name) flashes ''FF'' for half a second

so thats where its at..ive reset the RAM sticks and tried with only one stick but still same issue

any help would be appreciated!

EDIT: the PSU seems fine as i was using it to leaktest/ bleed my loop
