Go to your local auto parts store and buy the haines or chilton book for this car. It should cost less than 20 bucks.

When my computer is on the moniter is blank.


The monitor only has one cable and it is keyed to fit one way. They are always located under the top bezel. Should have roughly 20 pins and the wire will flow up into the display. If the screen is very very dim (look carefully) then your inverter board is most likely bad these run 40-120 dollars depending on model and are located along the bottom edge of the display itself. If the screen is completely black, try plugging an external monitor into your laptop (make sure you try toggling the display mode) [typically Fn + F7 or whichever says LCD or has a monitor icon.] If the external monitor works then your screen is most likely the problem and will need to be replaced. If the monitor does not work, the motherboard needs to be replaced. You will be hard pressed to find any schematics for motherboards but you could dis assembly the the laptop and easily check for descended capacitors, burns and the light though most of the time I doubt you will be able to see the damage.
Best of Luck

My 873 n will not turn on


if you are refering to a computer

Test your PSU or replace it if your power supply units fan is not working your PSU is faulty

One bad lead can cause a computer to continue on a cycle or to shutdown or fail to detect/ boot up a computer hard drive

Test all leads that attach to your hard drive including electrical extensions,IDE,SATA

the leads from your "((MOTHERBOARD TO YOUR HARD DRIVE))" make sure they have a secure connection and are not faulty or just replace them they could be faulty
make sure all leads that are attached to your drives dvd\cd 3 1/2 inch floppy have secure connections and are not faulty even the electrical extensions or just replace them they could be faulty a computer needs its connections to continue its cycle and have an end so any faulty leads will end up with a computer error even something as small as a faulty electrical extension or fan lead can cause this problem

follow the troubleshooting procedure a computer needs all of the data and electrical current to travel through every device and to have an end to be able work properly

a motherboard and a hard drive any leads between them will fail before your motherboard or your hard drive if its a flat ribbon 40 pin type IDE replace it this will be the first to fail check all electrical extensions make sure they are securely seated even the cd/dvd floppy drives need to have current go through make sure these drives are working also it could be a dirty computer clean all of the dust from your computer you could use a vacuum cleaner but whatever you use make absolutely sure there is no moisture gets to anything in your computer and before you touch anything be sure to wear an earth strap hope this helps

Hi i have a Codegen model 450x case and i am trying to install a Gigabite GA-P35-DS3R motherboard and am having troulbe with the start switch wires, the cases wires do not matgh the diagram in the...


I'm not sure what you mean when you say the case wires don't match the diagram. You might mean there is already a plug on the end of the wiring, and this plug doesn't match the board header. If you're reusing the case from a name-brand machine like a Dell or HP, this is possible. They often get custom versions of motherboards made, and their front panel connectors are usually a nonstandard layout. On the other hand, in a generic retail case, the front panel wires normally have separate connectors on the ends for the switches, indicator LEDs and any front panel USB and audio jacks.

This is the front panel header diagram I found in the manual for your board (I looked at version 2, but the connections should be the same if yours is a different version):

This board has an Intel standard layout for the header. If your wiring has separate connectors, the start (power) switch wires will plug onto pins 3 and 4. I have never seen a retail case come with anything other than a two-pin plug on the end of the power switch.

If you are dealing with a custom plug on your case's wiring, what you can do is remove the pins from the housing. They almost always are held in by a plastic tab on the connector shell that engages a tang on the pin. Use a thin object like a small flat-blade screwdriver or a knife tip to lift the tab and you can slide the pin out. Insulate each pin with small-diameter heat-shrink tubing if you have it, or a layer of electrical tape. (I prefer the heat-shrink tubing, which is neater and more permanent.) Then you can put each pin over the corresponding pin on the motherboard's front panel header. Unless the pins are very loose, they will stay in place by friction. I often use this technique when salvaging a case.

As for the CPU fan, be sure you have the connector over the right pins. Here is the diagram from the manual:

You might need to rearrange the pins in your fan power connector if they don't line up correctly. This layout looks a little strange.

Codegen 450w model :200x


Run a jumper wire between your Green wire on your 20/24 port plug that would hook to the mainboard and one of the black wires in the same plug. I would put a pushbutton or switch in between the Green and a Black on that plug. You may need to put a load on the power supply like an old hard drive or a CDROM. Plug your power supply in and you will notice the fan turning. Use your multimeter to test for different voltages on the connectors. You should get +/- 12, 5, 3 Volts.

I just went into my basement and tested this out and it works great.

Enjoy
