Computer wont work when 2x2 connector is plugged in
When i plug the 2x2 connector into my motherboard my computer wont start, it just turn on for like 1sec then turns off. When its not plugged in and just the 2x12 one is, all the fans on the video card, cpu heatsink, and case fans turn on fine and the computers stays on. But i cant do anything because the screen is just blank and nothing happens. I'm pretty sure the psu is not the problem because it ran my other computer just fine. And its 730w so im also pretty sure lack of power isnt the problem either. I dont think that the problem is it getting shorted out/grounded on the case either because it wont work sitting on my table either. Can anyone help me?

Under the main view photo at the top left; there are 4 views shown underneath. Click on the third view from the Left. Shows a top view of the motherboard. Now it is the main view. Click on the main view to enlarge it.
See the 5 blue SATA connectors under the Blue and Black ram memory slots? Red line points to them, and subheading states; SATA connectors; 6Gbps
IF you are going to add a SATA harddrive as a Secondary harddrive, use one that is open. (Nothing plugged into it)
Which one? Does NOT matter. The beauty of SATA is, that you can plug into any one of those SATA connectors, and BIOS will find the device that is plugged into it.
(SATA 1 connector is usually reserved for the Primary harddrive, though. The one with the Windows operating system on it. [Windows XP, Windows Vista, Windows 7, etc )
Looking at the connector for the SATA data cable at the top, note the L-shaped opening.
Looking at the SATA connector for a motherboard, shown on the bottom, note the L-shape where the SATA data cable plugs in.
The SATA power cable has the same L-shaped opening. Only plugs in one way.
Caution! IF, the SATA harddrive you are going to use, has a provision for a SATA power cable, AND a 4-pin Peripheral power cable, ONLY use just a SATA power cable!
Why? Because you will burn the SATA harddrive up! Maybe not right away, but I assure you down the road it will.
4-pin Peripheral power cable,
(Also know erroneously as a Molex power cable. Molex was the first manufacturer of that type of power cable connector. Name kind of stuck. Just like calling an adjustable open-end wrench, a Crescent wrench ),
The motherboard can support a 2x2 (4 pin) or 4x2 (8-pin) connector. The motherboard employs a foolproof design, as the socket on the motherboard is keyed to prevent you from installing the 2x2 in any position other than the correct one. The image below was extracted from page 24 of the manual.....you plug should be in pins 3,4,7,and 8.
Sounds like your wiring isnt right on the on off power. Make sure your power supply can handle this MotherboardAdapter cables are available that allow the incorrect use of older ATX or SFX power supplies in place of an ATX12V or SFX12V power supply. Intel does not recommend the use of these cables. These cables convert a standard 1x4 peripheral connector to the ATX12V 2x2 connector. An ATX12V or SFX12V with the 2x2 connector is required for all Pentium® 4 processor based Intel® Desktop Boards. Using the 1x4 converter cables can lead to system component or power supply damage and/or boot failures. The ATX12V and SFX12V power supply design guides (http://www.formfactors.org/)* recommend a minimum of 8A at 12Volts to properly power any Pentium 4 processor based Intel® Desktop Board. Standard ATX and SFX power supplies typically provide approximately 5A of current, which is not capable of reliably powering the Pentium 4 processor based Intel® Desktop Board. And I think the motherboards going to look for a formatted hard drive wired to the motherboard It wont boot off that USB stick.
Make sure the power cables are plugged into the pins properly on the motherboard.
Once you do this then go ahead and reseat the power supply connectors to the motherboard. Only hook up these two connectors from the power supply for now.
Try turning on the computer and hopefully you will get it to turn on now. If you can't then make sure the switch on the power supply is set to 115v. Once this is done try turning on the computer again.
If you still can't get it to turn on then try a known good working power supply or new power supply. If it still doesn't turn on then you know at this point that the motherboard is bad.
Hi, I think you are looking at the front USB pin aray connector. The on/off switch and LED light pins are usualy along the edge of the board nearest the front of the case. They will be marked with ID: lettering:- pwrs, hdd led,
rs-sw, pwr led. If your case has one block plug you will haave to gently seperate the segments and plug them on one at a time.
The power and reset switch will work either way but the LED will only work when plugged the right way around, it wont do any harm if they are plugged backwards they just wont work, so experiment. regards mistyman
