What are you asking for assistance with? Connecting the wires (if so which ones) or finding a manual?

What cables are you having trouble with? If it is the power supply cables you are having problems with, bear in mind that most modern motherboards/PSU's use a 20+4 pin arrangement. Some older PSU's have a different connector.

It could be that you need to update the PSU to match the requirements of the motherboard

Aspire 750 CPU case button destroyed.

I'm not overly familiar with this model...but assuming its a desktop, try this. Open the side panel on the case and try to find the back of the power button. If you can find it, and there are two wires that come directly from the back of said button, follow those two wires to where they connect to the motherboard. If they run into something else or there are more than two wires connecting to said power button, you may be out of luck and need to get a hold of a new button before you can turn it back on.

I take no responsibility for any slips and mistakes you should make doing the following, do so at your own discretion and beware of possible damage to yourself or your computer.

I used to work in a shop, and when ever we'd get a desktop with a bad power button, we'd turn it on by opening the tower, tracing the wires from the power button to the two pins on the motherboard said wires plug into, unplugging said wires, and shorting the two pins on the motherboard together for half a second with a screw driver. Naturally, I'll tell you to be careful doing this. I'm not responsible if you short the wrong pins and a)fry your computer or b) fry yourself.

Hope that helps and good luck!

I have a ECS A740GM-M Motherboard in an Asus TX-381 case. I can't get the 2 front usb ports to work. What am I not wiring up right?

Make sure you are putting the front usb header connector on the proper USB pin connection on the motherboard. You should see nine pins in 2 rows together. Check the manual that came with the motherboard to find the correct pins location.

How do I find a manual for the ULT40278. I'm trying to figure out you would connect 2 fans when some motherboards have only one fan connection?

Motherboard fan connectors typically use a small 3-pin which looks like this: zero_awake.jpg
the left connector is a female connection (the side with 3 holes) the middle and right are male connections, has 3 metal pins:
  • Black: GND (ground)
  • Red: +12VDC or +5VDC (12V or 5V DC - direct current)
  • Yellow: Tachometer signal (used to read fan speeds)
NOTE: Wire color may vary, and some fans or motherboards may control fan-speed.

Some fans use a 4-pin connection, which is generally a CPU fan connector but not always:
This pictures a 4-pin connection, but may look different from other 4-pin connections because the wires are covered in a black sleeve, which keeps them safe from harm and to reduce potential negative affects on airflow created when there are lots of loose wires inside a computer case.

This photo shows a 4-pin connection attached to a motherboard next to a 3-pin connection in a motherboard. While it is not recommended in the case of the CPU's fan, in the case of other internal case fans with a 4-pin connection, it is possible to plug them into a 3-pin connector of the motherboard, but the ability to control fan speed, which is controlled in the 4th pin will be lost.

Though sometimes computers have a way of controlling fan speed on a 3-pin or 4-pin connection even without the 4th pin, such *** voltage regulation and reading tach. feedback. These things are typically things a general user doesn't need to worry about unless their computer is running particularly hot and causing trouble.

In which case, it might be worth investing some money in a fan controller, which takes a power connection, several fan connections (varies based on the controller you get) and gives you the ability to control fan speed externally on your computer case. My controller has nice dial knobs, though some "fancy" controllers have a display and up and down buttons. (Fan controllers would be at your own discretion in terms of price, you can get them cheap all the way up to seemingly ridiculous expensive)

In the event of not having enough 3pin or 4pin connections on a motherboard, it is still possible to add case fans by way of 4pin molex connections:
A female molex connection

A male molex connection

Some case fans run exclusively through these connectors, others have a combination of a 3pin (or 4pin possibly, though I've never seen this combination) and a 4pin molex connector. In this case, the molex connector can connect directly to a cord from the power supply and run the fan. It is possible to run case fans without having them connect to the motherboard at all! Which makes it possible to connect more fans, with less available connections for your fans on your motherboard.

If a fan is a certain connection (any of the 3) and you need to convert it, for example:
  • a 3pin to a 4pin molex because your motherboard doesn't have enough 3pin connectors for all your fans,
adapters are available to change one type of connection to another, at many online retailers (such as,, or other electronic supply retailers) and some retail stores, Best buy might have something, though you'd have a safer bet at a store like Micro Center which is more specialized for PC building or an alternative PC/electronic store.

To ensure you solve your problem, just be sure to familiarize yourself with the motherboard you are planning on buying (or have) and the fans you plan to have inside your computer. It can be a bit more work to check the specs on the fans and motherboards, but a little work saves hours of headache later.

Need manual or instructions for connecting frint

The model of the motherboard is actually more helpful. Most of the FP Connectors will be labeled, i.e. HDLED +/-, PWR LED +/-, etc. Loook in your motherboard manual for which pins they relate to.

Read the labels for the connectors on the motherboard.

Polarity does not matter for the POWER and RESET buttons.

If the lamps for AC-POWER or HARD-DRIVE-ACTIVITY do not light-up when you expect them, then reverse the connector.

Try the PC SPEAKER connection one way, and then shutdown
the computer, reserve the connection, and start the computer.
If the "beep" at start-up is better, leave it as-is.
If the "beep" does not happen, or is quieter/distorted, reverse the connector.

Re: lg tower xp install

FDD Floppy-Disk Drive.
It would be advisable to go to the motherboard Manufacturers site. And download the setup or user manual for this Board.
The White or black plastic jumper blocks i,ve refered to, are on the back of the Actual CD/DVD Rom Drive. Located at 1 end. this should be set to Master or Slave. diagram of settings usually printed on top of the drive. I dont know whether you have an IDE Drive ( 40-80 strand ) wire connecter.
Or sata drive connectors. 1 single red cable from motherboard to drive.
please bear in mind, this site is designated to solve technical solutions.
i,ll help all i can, but if your not technical minded, perhaps this is a job for someone more competant than yourself. no disrepect intended.

regards mike @ compurepair.
