I am a cameroonian, age 24 and a worker with an NGO called LukmefCameroon as a System Administrator. I have so many problems on how to set jumpers on Motherboards, Hard drives, CD-ROMs etc so i want you people to help me with diagrams and notes that could help me.
You can contact me by email; firstname.lastname@example.org.
Waiting to read from you.
Different motherboards and hard drives use different settings for each application unless U work on identical machines with identical parts. MAXTOR,SEAGATE ( old er 1's ) QUANTUM,CAVALIER,IBM deskstar, etc use different jumper settings depending on the application.. EXAMPLE older maxtor hard drtives set JUMPER 50 to run as a master with no slave present jumper 50 is the jumper closest to the ide cable ..

Chances are that 250w power supply is not going to power a motherboard with a 24 pin connector, but you can try.
You will need to purchase a 20 to 24 pin adapter cable.

It is possible that the motherboard or one of your other devices (Drives, fans, video card) pulled down too much power and killed the supply, but it's far more likely that the supply was bad all by itself.
There's no way to remotely diagnose which part failed first, but if it were my system the first thing I'd do is buy a new power supply.
I haven't seen a 250W power supply in a long time -- is this an old computer or a modern system? Unless it's a specialized system that requires the smaller supply, I'd get a 400W supply or larger.
If it's an older system, make sure that the new power supply has the correct motherboard connections to work with your motherboard.
yes 20 pin connecter power supply is ATX(advance technology extended )power supply and old which was low watt and 24 pin is EATX (enhaunced advance technology extended) power supply is new and high watt so 4 pin connecter can be detached from 24 pin connecter and can be fitted in 20 pin connecter
I assume, you have voltmeter with you.
Set VOM to DC 20 V range.
Remove the Power Supply from cabinet. Be sure you have proper earth in your house/workshop.
On the 20/24 pin main connector of your power supply, short the pins carrying green & black wire.
Hook your voltmeter -ve on any black pin of the connector permenantly.
& then connect the mains power cord to your power supply.
If your power supply is ok, this shall start the fans of the power supply on & running. Now you can check the voltages on different pins. There is a sticker on your power supply showing the normal voltages on every wire.
If you don't see any / normal volatges, your power supply needs repairing. You can buy a new one/ repair existing.
IT sounds like the fan bearings are going out already, or have flat spots on them that cause vibration at speed. Try calling the manufacturer and tell them the fan either quit working or is about to quit.
