My rear panel ports aren't working??

Specs: N/A
HI, I just built a computer using the ASRock N68C-S UCC motherboard which supports AM3 chip and I put in an AMD dual core athlon AM3 chip. I plugged up my harddrive, dvdburner, put the cpu in the cpu slot, used the lever to lock it in place, put hte heat sink fan on it, I plugged up all the fans and power supply both the ATX and the 24pin power supply. Every cord is accounted for and none of my front or rear panel ports work. I push the power buttong, all the fans run, the lights on the power button come on, my dvd drive opens and closes but My monitor wont come on, the usb ports wont work. I was wondering what the issue may be? The processor I bought was brand new and i used an anti static wrist collar when handling it. The monitor Ive used on 2 different computers now and it works fine and I even used the my keyboard i used on my old computer and it's not getting power. I cant do anything because theres no feed to the monitor to even get to the bois.

Ports aren't going to work if the computer isn't running.

You didn't mention anything about RAM.

Did you use thermal paste or pad between the CPU & heat sink?

Did you connect the secondary 4 pin 12V power connector for the CPU that plugs directly into the motherboard by the CPU.

Is your CPU on the list below of processors that work with that board.

You should always bench test the board before installing into the case.

What brand and exact model power supply do you have?

I am using the AM3 Athlon II X2 ADX250OCK23GQ which is on the list. I have 2x2g ddr3 RaM. I did plug in the 4 pin ATX power connector coming from the power supply. The case and power supply are Rosewill R218-P-BK-450W ATX Mid Tower Computer Case, come with 1x 120mm Fan, 450W Power Supply. I did use the paste between the heat sink and the processor.

Well, I suggest you go back to the bare essentials and try posting with those. power supply properly connected to board, Board, CPU w/heat sink/fan, 1 stick of RAM, monitor connected to integrated video, keyboard.

No other components connected. No drives, USB, mouse, case to board wiring, external hardware, etc. Start the board by temporarily shorting the start pins on the board with a screwdriver. Board should POST to a message indicating not system disk.

If the board still will not post then remove from the case and bench test with the same components. Still not go, connect a CD drive and run memtest86+ after downloading and making the disk on a suitable computer.

NVIDIA® GeForce 7025 / nForce 630a

onboard video

AM2+ mboard.
Can use AM3 cpus

Your 450 watt PS probably has more than enough capacity to handle your mboard if you use the onboard video, but are you using a video card in a slot ?

If you ARE....

Your power supply must have at least the minimum capacity required to support a system with the graphics card you are using installed, or the max graphics card you might install in the future.
(Onboard video - video built into the mboard - IS NOT A CARD ! )
If that info is not in the ad for the video card, you can go to the video card maker's web site and look up the specs for the model - often under system requirements - the minimum PS wattage, and, more important, the minimum amperage the PS must supply at 12v is stated. If you don't find that, any card with the same video chipset including any letters after the model number has very similar minimum PS requirements. Some power supplies have two or more +12v ratings - in that case, add those ratings to determine the total +12v current capacity.

If you're a gamer...
In most if not all cases, the max capacity rating of the PS is an intermittent rating. It's recommended that you do not load your PS to any more that 80% of that rating if you are going to be using something that puts a constant load on it, such as playing a recent game for hours on end. In that case, you multiply the min capacity stated for the system with the particular video chipset on the card by 1.25 to find the min. capacity of the PS you should get.

It is easy to test for incompatible ram that has caused your mboard to fail to boot.

Make sure you have a speaker or speakers or the equivalent connected to the mboard so you can hear mboard beeps (see your mboard manual if you need to).
Remove the AC power to the case/power supply.
Remove all the ram.
Restore AC power.
Try to boot.
If nothing else is wrong, you will get no video but you will hear a pattern of beeps that indicate no ram is installed, or a ram problem.
E.g. for an Award bios or a bios based on one, that's often a beep of about a half second, silence for a half second, a beep of about a half second, silence for a half second, continuously.
