No display : How to identify a potentially faulty component ?

[puraido]

Hi,

I've just finished building my first custom PC but unfortunately it won't display anything on the monitor despite all the time spent trying to solve this issue and check if everything was in place.

I've come to the conclusion that the problem comes from the PC itself and I'm planning to return some pieces among CPU, PSU, MB and RAM.

So I tried turning the PC on without RAM nor GPU. The first time the speaker did beep 3 times in a row but I just did it again and it doesn't beep anymore although the EZ debug LED is on.

Can I conclude something from that ? That the RAM and MOBO are ok since the EZ LED turns on ? Or at the the opposite that they aren't ? Is the PSU guilty ? How can I check the CPU ?

Thank's

Take it out of case. Put it on a piece of cardboard. Try again. Clear the bios.

I've already tried "breadboarding" with no luck.
Cleared CMOS 3 times.
I've pretty much checked everything on the list (removed CPU 3 times checking for bent pins, moved ram sticks everywhere,..)

I'm not the kind to come to complain before trying to solve things by myself but I'm pretty much at my wit's end.
That's why I'm planning to return some stuff
