New custom pc not booting

[3.0charlie]

Do you have any other parts you could use to help in trouble-shooting?
Did you clear / reset the CMOS?

[Gokul]

Yes I did

Well I think I did

After doing so the light isn't turning on on the mother board when i power the psu now...

You have to have other parts to confirm which one does not work anymore. Put emphasis on the board and the PSU, since you can't power anymore.

Hey guys my mistake. The motherboard's light is on.

If the PC were to be full working, when I switch on the psu power (not the power on button on chassis), is something else supposed to happen? other than having a green light on the mobo..

also 690 case doesnt have a speaker, i can't tell if mobo is detecting errors or not...

how can i diagnose this?

Once you flip the switch on the PSU, nothing happens - except some lights my come on on some boards, just like yours. Did you check the board's connections to the front panel? If you installed the small 2-pin power switch connector the wrong way, it won't start.

It's very difficult to troubleshoot a system without a speaker and spare parts.

Re-seat everything, all power cable, video cards, pci cards, then try booting with one stick of ram (Remove one and leave one in the first slot on your motherboard).
A common problem with OCZ ram is that it is not getting to correct voltage for your computer to boot properly. If you use one stick of ram you can usually boot enough to get into the BIOS to set the ram voltage, after that shut down and put the second stick back in and you should be good.

To find the correct voltage, look at the specs on OCZ's website

If that still doesn't work, depending on your location one of us might be able to send you a spare speaker that you could use. I know I have 2 or 3 around here...

Hey guys, i found out what the problem was. The fan connector leads from the psu were 4 pin while the mobo had 3 pin. Right now I am running the new rig, in fact im posting this reply through it ^^;

are there are options to tackle this issue?
i tried just putting 4 pin cables on the 3 pin mobo but it doesn't work

You'll have to explain this one a little bit better, 'cause I'm totally confused. Which connectors are you talking about?

I think he means that his fan is a 4 pin header (just like the 3 pins).. Oh man wait a second, I've never seen anything like that..

Yeah we are confused, both of us for sure
