If you use ATX power supply

Follow these steps

Switch on the power supply

Hold the power button approximately for 10 Secs , your system will be switched off. Now switch on the power supply and press the power button to return normal operation.

Some times pressing reset button also solves the problem

If above procedure fails , please check for any loose end connections inside the cabinet. memory slots, any pci slots also check the battery .


Hope this would help
Best of luck

What do i do when my computer wont turn on at all and the screen says "NO SIGNAL"


Your CPU may not be getting power. You need to start there. verify the plug is plugged in to a known working recepticle - ie plug a lamp in or your monitor for that matter - exact same plug. Once sure, then verify your power supply switch has not been switched by accident. get a light and look physically at the back where the fan is. The switch is obvious - with a 0 or a 1 - the 1 needs to be pressed in. If the CPU still wont turn on, then the power supply is likely bad - especially if no beeps. If this is the case, you need to replace the power supply. I would take your cpu in to get checked as you may have blown your cpu completely and you dont want to buy anything for a dead motherboard.

Things to try:

1. Check that the cpu fan is properly connected to the correct port marked CPU FAN.

2. Make sure the power cables are connected correctly to the motherboard.

3. Test the button switch with a multi-tester to make sure that it tests good.

4. Make sure the power switch is connected to the correct pins on the motherboard.

5. With the computer off pop the cr2032 battery out and pop it back in after a few minutes.

6. Test the power supply with either another motherboard or a power supply tester.

7. Test the motherboard with another power supply.

8. If all else fails replace the motherboard I have had a bad one from time to time even out of the box, and if you have a spare cpu you may want to test with that also. Cpu's hardly ever go bad I think I have had two go bad ever, not counting power surges and storm damage.

CPU fan runs at high speed and won't boot


Change the setting in the BIOS menu. reboot your computer.. when you see the dell logo.. press F1 (or F2 if F1 doesn't work) button until you see the BIOS screen. Check for fan options and change it

Ensure that the power button is pressed and the monitor is plugged in correctly. If ok, then the installation was stopped while installing your video drivers. If possible use another monitor to re-load the xp operating system until completed. Once the video monitor drivers are loaded the monitor will work again. Let me know if you have any questions.

My DC5000 SFF turns on okay then switches off randomly Help!!


Which fan are you referring to? As far as I know the fan in the power supply runs at the same speed at all times. So if that is the fan you are hearing it may indicate that the power supply is failing. The power supply may be over heating and shutting down. I would try a different power supply if you can get your hands on one.

You can test the power button. Remove the wires from the power on pins on the motherboard. Momentarily jump the two pins with a small screwdriver. If the computer starts the power button is bad. If it still doesn't start then something else is wrong. Did you test the memory? Also do all of the fans work, especially the CPU fan? It can't hurt to test with the other PSU. You know the HDD is good. Test one piece of hardware at a time and hopefully you will find the problem.

T2893 e machines wont turn on


It sould be as simple as the on/off switch being bad .. the power supply could be bad .. it is powering the 'led' enough but it is faulty and cannot power the machine.

Try disconnecting all the components .. cd, hard drives, floppy ,etc .. but leave the power plugs on the motherboard .. try ...see if the CPU fan or power supply fan spin up..

Power problem


NO POWER Maybe you have a faulty Power Cord try replacing that first. Secondly check your powersupply's Fan if its turning. Lastly check your power button maybe its defective. SWITCH PROBLEMS A trick can be done here. Unplug it then spray the switch (Soaked) with warm distilled water with mild soap. then let it dry using a Hair Dryer. Then test! If failed, Replace the switch. If Persists then There is a problem with the Main Board or Power Driver. FOR LONG BEEPS, ONE SHORT BEEP IN AN ENDLESS LOOP, BLUE SCREEN OF DEATH AT STARTUP Try using Memtest 86+ http://www.memtest86.com/ to diagnose your memory problem. You can also try the following methods. Turn off power, Unplug. Remove the cover of your PC. Remove the memory from the Motherboard. Note on the locks! Clean the memory contacts with an eraser yes that's right a rubber Pencil eraser. It should be shiny gold. Reseat your memory to the motherboard and Test! ====================== If you are having trouble with Newly bought items save your self from headaches by returning them and demand a replacement or a refund! You may have purchased a reconditioned\repaired\factory defect product.
