    My PC was having a delayed reaction to me pushing the power button and the PC switching on, then one day, i pushed the button and it never turned on, i have tried replacing the lead, refixing the 'Power SW' Pin on my motherboard and taking off the front panel and checking the power wire, i have also tried to secure all the power input leads from the power supply to various slots on my motherboard and components.

Acer Veriton X4610G will not power on

There are a couple of ways we can quickly try to solve this, however they only work if there isn't a hardware fault. First off, pull the power-cord out of the back of the PC, then press the power-button on the pc case- the one you use to switch it on and hold it in for about 30 seconds. Let go of the power button and re connect the power cord. Try to switch on the pc. If this works, the problem was a build up of static electricity in the PSU which occasionally causes the pc to not switch on - its pretty common. If this doesn't work, then you are probably looking at a replacement power supply. These are pretty straight forward to replace, however, from researching the X4610G, it looks like they are a small PC and so don't use a standard size Power supply. If you are happy to have a play, search on ebay for a replacement supply-just type in your pc name and model and add PSU then use this information to hunt for a quality replacement. You need to make sure the wattage is at least the same as the one you are taking out. This is displayed on a sticker on the side of the PSU. You will need to remove the case to find this out usually. Then remove the case and carefully unplug the existing PSU from the motherboard, hard drive, DVD drive etc. Then just replace the old with the new and reconnect the power to the Motherboard, DVD etc. Once done, replace the side of the case and switch on. Hopefully this should be you sorted. If you are not happy about doing it yourself, expect to pay anywhere from 50 GBP-100 GBP for a technician to do this for you (including the part). Hope this helps

Dell computer wont start up

Tough one, but inspect the motherboard for a blown capacitor. You could test the power supply with a simple voltmeter. Not to mention simply seeing anything lit with the case open while powered one. gl

Dell Optiplex SX260 was turned off last night. This morning it will not power up. The PSU, located in the brick, has a green light and reads positive on an electric tester placed near it. We have even...

There are a few things that you can check for in this case. On the back of your computer, often times there will be a switch located somewhere near the spot that you attach the power cable. This can accidentally be switched off. If not that then you may have a faulty power supply (which is easy to replace). This is the unit inside the computer that converts the AC from your outlet to useable DC and supplies it to the drives, motherboard, etc. etc. It is not the easiest thing to test but is likely the culprit.

The electric cut and when it came back on the computer did not

Hi this happened to me a few weeks ago.
I disconnected all other appliances (printer, scanner etc)
and tried again-the pc switched on! It seems the power cut had blown my scanner and while connected to my pc prevented it from switching on (to protect the pc I assume?)
If that doesn't work, it may be the power supply to your PC was damaged, in which case you'll need to purchase a new one (not too expensive)

PS When you get it working again, invest in a power surge protector, again not too expensive on Ebay etc.

Good Luck!

Pc will not switch on ( no power )

Check cable first, make sure there is power to the outlet, see if there is a power switch in back of the machine that got toggled off. If none of this works yo may have a power supply that died. The ony way to check it is with a volt meter. I have no idea of your level of expertise, so I will stop here. At this point it's time to replace the power supply if it doesn't read any voltage on the pins. Usually this dosen't happen all at once. unless it went while you were using it, "which I don't know from the question". if it just won't go on and it worked when you last used it, it is likelly an external issue, cable outlet connector etc.

No response from power on button

Is there a light indicator beside the switch button indicating there is a electric current coming in? It should light when youpress the power on button, If none, better check the power supply or the fuse at the back

Ok i neeed help!!!!!!!! on my power supply there is a switch which you can move to 115 volts to 230 volts. everytime i switch it to 230 volts the computer wont turn on? why is this happening? when i put it...

This is the power supply for your PC, depend on your local country power supply, some country like North US may use 110 V in their daily use electrical stuff and some country like Euro, UK use 240 V.

Your PC power supply is design to suit this 2 type of power input so can be sold everywhere. What u need to do is to make sure your local country power supply voltage and then just switch the input correctly, i think u have done it.

No power

There may be a fuse in the power supply. It is a lot of work to get the thing open to check but probably worth it if the fuse is blown. On the other hand, it blew for a reason, and after you replace it, it will likely blow again unless you can find the reason for the first failure.

Note, there are lots of dangers connected with going inside your e-machine or any other computer for that matter. Among then - Static discharge - bumping connections loose - not remembering how to reassemble - dangerous voltages in the power supply.

Use extreme caution and take pics with your cell phone of everything you do.

I hope you find this to be of some value.
