Did it work before? IF yes Dell put this little strip of lights in the back of the machine that should light up and also on the motherboard. If nothing lights up and it is the original parts it may be the powersupply or motherboard

Compaq Presario SR2020NX will not turn on at all. Any ideas, people?


ah a tower

you check the power source output
this can be replaced as a whole unit

at power up should be a beep
if the mother board is good it will start up its default
before loading from the hard drive

make sure the dust is removed from all the internals
clean all the contacts
the fans and cards and main board

The power light wont turn off


Does the PC turn off at all or just not the light. If it's just the power light on the tower, Check the connections between the tower to the motherboard and make sure they didn't get moved when the power supply got replaced.

Gateway 500C: Dead. green PSU lite doesn't lite when pressing test switch


Hi Don
first thing to check would be all power leads and fuse to clear those areas from the list. Providing all of these are correct, it looks like either your power button has gone faulty of the power supply itself. I am not familiar with this particular machine, is it a normal tower sized machine? if so then a psu replacement is relatively cheap and easy, just make sure that the replacement has all of the connections that you require.

NO Post test beep.- no boot screen


Could be a dead PSU, mother board or CPU to me.

First check the power source, are all connections good and switches on.

Assuming so, are there any led's lit anywhere on the tower when you turn it on or any fans turning other than the PSU fan.

If there are no fans, including the PSU, then the PSU has failed, if there are fans and led's lit then turn it off, remove power source, remove the cover and check whether the PSU is properly connected to the mother board properly (Large multi-pin plug) if it is connected properly,

After this, you need proper test equipment.

Hello, Last night I shut down my Dell E510 desktop - the proper way - by going to the start menu, shut down, turn power off. Then, today, I pressed the power button on the front of my tower and...


This sounds like a definite power issue. This means that the problem could range from being as simple as the power button itself not working/disconnected to the power supply being dead.

Things to try:

1. Have the side of your computer open and press the power button. Notice if any fans start to move or anything that happens.

2. Do you notice the Hard drive light flashing at all when turning on?

3. Has anyone else been using or been close in proximity to the computer that could have bumped it, causing something to come loose?

4. ONLY if you feel competent enough, check the cable connections inside the computer. Make sure to disconnect from the wall for 30 seconds and reconnect before touching any cables inside. Leaving the cable connected allows the computer case itself to act as a ground to prevent static shock.

Good luck!

MY DESKTOP CUMPUTER WONT TURN ON


I know you don't want to hear this, but first thing is to check that the computer is plugged in and the switch on the power supply (right next to where the power cord goes into the tower) is turned to the on position. Also be sure the outlet you are plugged into is in good shape, you might have blown a fuse in your house or something like that to make the outlet dead.
If this doesn't work then I need to know what kind of audio/video response the computer is making.
If there is no noise at all when you push the power button on the tower, then you more than likely have a dead power supply on your hands. You will need to buy a new one that is at LEAST as powerful (same KW rating) as the power supply you had in there previously, if you haven't upgraded the computer's hardware since you bought it.
If you have speakers on your desktop and you hear the windows boot-up sounds then you either have a problem with your monitor or with your video card. There are other problems on this website you can refer to in order to trouble-shoot your video card.
There are several other possibilities if your computer is making noise (fans spinning up) but not getting anywhere:
You can be hanging on the BIOS, you need to reflash the BIOS - contact an IT Professional or look around this forum for a solution.
The Boot Sector may be corrupted, contact an IT professional or look around this forum to perform a checkdisk externally on your drive to repair the MBR.
Please post back to let me know how this goes! Good luck.
And please rate my response.

After press push buttom , power not on , fan not on ... as dead


It might be the power supply that is dead or motherboard or together.

1. Try to disconnect all the connection at the back of your computer tower then press the power button of your computer for 15 seconds to drain the remaining power.

2. Reconnect only the power button and the monitor cable then turn it back on. (If the same thing happened go to step 4 if not go to step 3)

3. ( From step 2 ) If it turned back on, most probably the problem is one of the devices that you just disconnected is causing the problem. Try to reconnect then one-by-one and each time you connect them turn on your computer, let's check if it's gonna turn on or not, just proceed until you finish connecting all of the device or until you pin point the root cause of the issue.

4. (From step 2 ) If it didn't turn on, Open up your computer tower and reseat the video card, then turn on the computer

5. If still the same problem, remove your hard drive and turn on your computer, if it turned on, meaning that the hard drive might be the problem, if not, just put it back in

6. If still the same problem, remove the memories from your computer, if you have more than one memory installed remove them all, test the first memory to the 1st slot and to other slots one-by-one, see if it turned on. Test the second memory and so on, to the 1st slot and so on. Do it only with one memory testing each memory.

7. Reseat the power cord coming from the power supply, the 21 pin and also the small one that is plugged into your motherboard,

8. Reseat the CPU

9. If all of those things failed, most probably that the power supply is causing the problem. it's also possible that the motherboard is affected, I hope not.

It is stuck in power saver mode tried every thing can not get in come back up. Tried turning off and on, unpluged and pluged back in, put in cd, tried starting in safe mode with F8 key.


Possible that it's caused by a faulty hardware

1. Remove all the connection at the back of your computer
2. Power cycle your computer tower by pressing the power button for 15 seconds
3. Plug the power cord back in and monitor cable at the back of your computer tower (if it turned on, meaning that one of the device plugged at the back of your computer is the one's causing the problem, for you to pin point the problem, try plugging it one-by-one and turn on the computer each time you plug a device)
4. If it keeps on doing that, open up your computer tower (be careful to unplug the power cord and power cycle it to avoid static electricity)
5. Reseat the video card, turn on the computer again, if it's still occurring
6. Reseat the IDE/Sata cable of your hard drive and try to make sure it's properly plugged in, turn on the computer again, if it's still occurring
7. Reseat the memory, turn on the computer and test it again if the same thing
8. If you have 2 memory chip inserted in your computer tower memory slot, remove the other one and turn on the computer, do the same thing to other memory and each slot
9. Reseat the CPU and start the computer.

I have a Emachine W3650 And it wont start up what do i need to do ?


If it's completely dead when you turn it on, you probably have a bad power supply. They're fairly easy to replace and not too expensive unless it's proprietary to your machine, some are. Most towers will take a universal type power supply.
Also make sure it's plugged into a good power source, power strips and things can be flaky at times.
