Hi ive just put my new rig together, it was my first time and so far this is the only problem i have run into

I have a gigabyte 970a ud3 motheroard and amd fx6300 and a 530w be quiet l7 psu

my pc seems to be working okay now but im not sure if im doing the right thing, I put everything together last night and got a bit confused when i fond the 12v power plug near the cpu is 8 pin, coming out of my psu is 2 4 pin plugs for this 1 labeld CPU 1 P4 & the other labeld CPU 2 P8, after doing a bit of reading around i decied i should put both of these plugs in, they do both fit but it is very very tight,

once everything was wired up i went to turn the pc on the first time and got nothing, i tried a few more times still nothing, so first i checked all my wiring to the power switch etc... that was all fine, then i imeditley went to the CPU plugs as these were the only thing that had caused me confusion first i remoed the top plug witch was at the time CPU 2 P8 witch is in pins 3,4,7,8 still nothing so i took the bottom one out and placed it in the top plug.... then i had power fans everything, and the pc posted just fine..... i havent touched it since then.... can anybody tell me why this is ? am i supposed to have both plugs in, from what i read last night it says i am ?

would really appriciate any advice on this.

Also can i just confirm my pc is POSTing sucesfully,
when i turn it on i get the gigabyte screen, then a page that flashes so quickly that I cant read anything then a page telling me its trying to boot from cd rom but fails as there is nothing in there.

is this correct ?

thanks in advance

Chris

The the 12v 4 pin connectors werent obviously connected in the right socket, probably to do with grounding etc.

About your second question you might have the cd drive as 1st priority boot in the bios.

thankyou i feel relly stupid i just put P4 on top and P8 on the bottom all is working fine now.

I dont have any cd's in the drive, i havent even beeen into the bios yet i think i may have plugged the cd drive into a lower number sata port but what i was asking is for it to get to that screen would the POST have to have been completed sucesfully,

Thanks for the really quick answers
 
Both CPU 1 P4 and CPU 2 P8 connectors should be joined to make a single 8 pin connector, then it should be inserted on the motherboard's CPU connector. From what I understand, you initially inserted one 4 pin connector at a time?... that may have caused the initial problem.

Your present problem if still any:
If you want it to boot on a HD with installed OS it will not boot till you repair install it, and if your Hard Drive is new, it's obvious the system is asking for a CD/DVD to start a new OS installation.
