Desktop pc e machine 4210

We have just bought a psu and fitted it to our already dead box. It now (once plugged in) flashes, rapidly the dvd drive, the mouse and the little light on the box. But it wont power up properly. Can't afford new one. Does anyone know ball park area what it sounds like is wrong?

    As soon as you connect the power wire to the box it whirrs constantly and the mouse light, the dvd light and the light around the on button all flash rapidly. You don't even have to press a button to turn it on. To cut power we have to pull the wire out of the box. There are no messages to monitor. It is almost like the computer isn't joined to the rest of its bits. (monitor, mouse etc)

Replace the case power on switch or disconnect from pins on m/board and switch manually by shorting pins together momentarily, i had similair prob but was resolved by holding the power switch in while switching the power supply switch to on, would fire up instant and the case power switch will only turn pc off.

Hello Anjji
You must have a low voltage power unit, you need to know that your PSU need to be equal or have more power than the one you lost, but carefully again try to recheck cables, and install just the HArd drive power cord, and one of your CDROMs, turn on the PC, and see if power on fine.

Are you getting any messages when it tries to power up. Or is it just going through the motions and stopping. Is the monitor showing the boot up process.

    Is the power supply wattage the same as your old one if the power is incorrect it can cause all sorts of problems. Check to see if it is the same. Different motherboards require different power supplies



    One comment i would like to tell you is to be careful with handling powers supplies. Even when you unplug a power supply there is still live parts working inside. don't go opening it up or anything.

  • Sean Treacy Dec 09, 2007

    When you replaced the power supply. are all the connections connected to the motherboard the same way as the connections when you took out the old one.

Power button on dell 5000 flashing amber


***I'm pretty sure your power supply is dead, you will either #1 take to repair shop or #2 replace it yourself.

The Best Value 550W Gold PSU 12cm 24-Pin 550 PSU is compatible.

The Corsair Memory 550W VX PSU is compatible and Corsair is an excellent brand, but you may have an issue locating the excess power connectors inside the case.

The Xilence XP480-12R Power 480W Quiet PSU would be fine, providiing the "hard drive connectors:2', are 4-pin Molex connectors.

E-MACHINE 6532 WON'T BOOT


Could do with more info here
1.) Does the machine power up (ie is the power lED lit and are there signs of activity such as the cPU fan running, hard drive actuating and lights to the DVD rom drive, if not, worth checking the pSU is giving out power, the easiest way of which is to substitute a new PSU.


2.) Can the computer access the Bios (F1 or Del or F2)? If it can, does it "see" the hard drive and DVD rom?

3.) Are there any beeps when it tries to start up? If not, the cPU is most likely dead

can you clarify any additional symptoms if (1) does not solve them

Emachines T2042 does not power up. what could be the reason? a faulty switch or a faulty power supply? The power cord is fine. There is also some spark when I plug the power cord into the cpu whiles its...


Not usually, what you need to do is see if the fan in the back of the PSU, runs at switch on... If it does NOT, there is a good chance your PSU has "Blown" this is a simple replacement, and quite cheap. You need to troubleshoot the PC, you need to also see if the fan on CPU goes at all, even a "Flick" at turn on? To see whats what, remove all Drives DVD and cards, then power on, if No GO then probably PSU.. IF OK replace things until, it stops, that is your problem.. Also remove a stick of RAM, and swap about if two to test them... A machine will boot with just RAM, but will complain..remove and introduce things one by one until you find problem, if you do all that and it is NOT, the, PSU, RAM, CARDS, HARD DRIVE, DVD, then it is your Motherboard. Try that see how you go.

Dimension 5150 dvd rw stopped working


Open the computer and reseat all of the connectors, and memories.
if the machine is full of dust and dirt, then you need some compress air to clean them out. power supply, under the motherboard, hard drive, floppy drive.
flashing yellow lights means that either the Hard drive is not starting up or the momories is not present.

Hi,
Im assuming this is a desktop computer.
I ask this, because sometimes people post in the wrong categorys.
If your getting no power, Then the first steps, are as you,ve already done, checked the plugs main fuse. Should be rated 3-5 Amp.
The next suspect item, would be your computers PSU ( power supply Unit ) This can only really be checked with a multi-meter, if you take the side/top panel off. ( whichever Applies ) Towercase Or desktop.
You have an internal Power supply unit. This provides power to Motherboard, and internal hardware Devices. Hard-Drive CD Rom And any other internal devices. You,ll see a Square Box to the rear of The Computer, with several cables coming out from it. The Majority will Have 1 Red @ 5volt 2 Blacks Earth or ground And 1 yellow Cable @ 12 volts.
There may be an internal quick blow fuse in the PSU Itself.
To attempt to remedy your issue, i,d suggest to remove ( unpowered switched Off ) the 4 Pin Connector To the Hard-drive And the CD/DVD rom. These 4 pin Plastic Plugs are refered to As molex Connectors. simply pull the plugs, towards the rear of the Computer. HD/DVD Drives Only. Then try to power On Computer. this will eliminate, a possible hard-drive failure or seizure, and also allow the PSU extra power for booting up the Computer.
Other probabilitys are broken or faulty, power/On case switch, but quite rare.
If you follow these steps, and get some form of life from the Computer. Please let me know, and i will guide you further.

Mike @ compurepair.
