Double check that you connected the power switch to the correct pins on the motherboard.

also make sure you have conntected the extra 4pin power cable to the motherboard, its a diffrent cable from the 20 or 24pin power cable.

One bad lead can cause a computer to continue on a cycle or to shutdown or fail to detect your hard drive
Test the leads that attach to your ((hard drive from the motherboard)) or replace all the leads that attach to your hard drive including electrical extensions + IDE,SATA and the ones that attach from your ((motherboard to hard drive))
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 are probably old and faulty a computer needs its connections to have an end so any faulty leads will end up with a computer error


hope this helps

Hi. Were you able to see the the DELL post screen when you turn on the computer? Take out the battery and unplugged the power adapter from your computer and to the wall socket. Press and hold the power button for 30 secs. Put everything back in then turn on the computer.

Computer not working. checked the power sup & its good. I see a light blinking in the mother board (next to the power connecter. How can I fix it?


Hmmm... if it won't turn on make sure the power button is pluged into the motherboard correctly.. if it is already and your computer still won't power up try switching out the power supply because sometimes they only go out partially, i had that happen with my old computer, the pwer supply only powered half the motherboard and unfortunantly it powered the cpu but none of the fans and completely fried my processor. Hope this helps, Daniel

I installed everything the CPU, RAM, and everything else. Connected all switches at the right places and the BIOS is on normal operation. I turn on the computer and its a blank screen nothing shows up....


ok, looking at the specifications All I can recommend is the following. double check the Video card to make sure it is properly seated and that it does not exceed the capabilities of the motherboard. 2 Disconnect everything from the motherboard except the CPU and case wiring/power supply and turn the computer on. If the system completes the post test, you will hear at least 1 beep and should hear several for the video card not being connected, then start installing components 1 at a time till you find the one causing the problem. Start with the Video card and then the ram as these are most likely where your problem is unless you have a faulty power supply which will be the problem if you don't get a completed post with nothing else connected.

Shut it off


Explanation sounds like motherboard or SMPS problem.

Try removing all your cables from motherboard including hard drive and other cables. Make sure to note down the power button placement on mother to later set it up the same way. Also need to test motherboard

Unscrew your motherboard from the cabinet and tilt you cabinet, place some plastic or wooden peice on cabinet and put your motherboard over it. Connect VGA Cable & Keyboard to motherboard. Now connect the power cable to mother board. Looks like one in image and try powering on by connecting only powerbutton cables. See it allows you to on CMOS setup. If it does, try connecting hard drive cables and try booting up. If doesnt work, finally hope my recommendation might be of some information

Recommendation
Replacing either would be less costly then getting complete new computer. You already have rest of things just get a good & latest package of CPU and Motherboard.

I am updating my N73 mobile software, but after updating .cellphone is not on.


I am sure your handset does not completed is updating during installation from net. Reason network or data cable connection disconnected from computer. Same problem was happened with my Nokia N73. If i am not wrong then when you press your power button, nothing is happened. Its look like a dead body. Don't worry just visit Nokia service center and tell them you want to install the update version & hand over the phone. You can't install the software from home, because your hand set complete dead. Its takes 2-3 hours for installing. But as per there work load may be its take 2 - 3 days for service center people.
Thanks & waiting for your feedback.

Problem to switch on the cpu


Disconnect the UPS from your configuration,
and connect the AC power directly to a wall outlet.
Press the ON/OFF button and release it.
If nothing happens, press and hold the ON/OFF button for 10 seconds, until the computer turns itself completely off.
Then, press the ON/OFF button, to restart the computer.

I have an hp 754n that will not turn on.. the green led on the back is lit up but when i hit the on off button nothing happens


i would say there is a problem with the motherboard, you could check to make sure the power supply is connected, if you don't know what a motherboard or power supply is, i would advise that you take the computer to a technician, you could injure yourself, or ruin the computer completely if you attack it with a screwdriver
