first custom build computer! need help...

[TypeZ]

how many power supply cords does the gpu take 1 or 2. my radeon 5870 takes 2 connections. my psu as only set up for 1 connection so i had to buy an adapter.

do you get a beep in the beggining. no beep means its a cpu prob i think. a crazy beeping sound means its a memory prob. also you could have the speaker that makes the beep hooked up wrong if theres no beep so makes sure all the case connections to the mo-board are right.

in this order:
double check case connections
cpu
memory
gpu power connections and connections to monitor.

also try to start the computer with no memory you shuold get a crazy beeping sound. then try to start it with no cpu. listen for a difference in beeps at startup. if you get one longer beep and 2 short beeps its vid card error i think. test this by starting your pc with no vid card in it.

I will try start the computer with no memory, and without cpu. but the graphic part is already cover. my graphic card only use 1 connector.
