Solved can't get my computer to turn on with all things plugged in

November 10, 2013 at 12:15:23
Specs: Windows 7
My computer won't turn on, it has a green light flashing in the back but no power will come
on. it was plugged in but not on. It was in a power strip that had other things plugged into that still work but for some reason it will not turn on when I press the power button. It keeps flashing a green light in the back even when the power plug is not plugged in. I am using my daughters laptop (which I hate using) to get some information. Is there a reset on this computer? I see two buttons above the green light, one is red and one is green, would pressing one of these help?

It's probably broken/busted/kaput and not in sleep mode. But IF it is in sleep mode you can try starting it up and start tapping F8 before the OS would normally start to load. If the boot menu comes up you can try 'safe mode' and if it loads do a shutdown and restart in normal mode.

But if it is hardware fault you can first open it up and temporarily remove any unneeded cards and disconnect all the drives. Do that with the power cord disconnected. Then reconnect the power and start it up. If you get a normal posting or logo screen then one of the disconnected items is likely at fault.

If that's not it, it's the power supply, motherboard or both. (Both because sometimes when the power supply fails it ruins the motherboard as well.) If you have a known-working compatible power supply you can swap it in and see if the PC works then. There's also something called a 'power supply paperclip test' which, while not foolproof can give an indication of its status. Here's a pdf download that explains it:

Without more information we can't help you. Post the model of the computer and the version of Windows. Also provide some background information. Like did this happen all at once or were there other issues before.

here is what I found on my computer for model number SR1850NX also found this other information cel 2.53, 1gb, 40GB and also AMD 64 Athlon, I don't know what any of this is, I just know I like desktops that I can play my games on. I don't use it for much except facebook, email and a few other things. I don't download hardly anything. I have microsoft security essentials for virus protection.

also as for the green light that flashes, there is a red thing under the power cord and above the green light that I don't know what it is for

Where did you get the information you posted in #2 above? The model number you posted indicates you have a Compaq Presario made by HP. It came with an Athlon 2.2Mhz processor. I am wondering where you are seeing the Celeron reference.

Your computer came with Windows XP Media Center Edition pre-installed.

Where are you seeing the lights? On the back of the tower?

Are you sure you are unplugging the correct cord? Sounds like there must be some power going to the tower.

So when you try starting the computer you hear nothing and see nothing on your monitor, but you do see the lights on the rear?

Unplug again and then press the start button a few times. Plug back in and try starting it again.

Sounds like you might be in sleep mode.

The 'red thing' on the back of the power supply might be a 115/230 voltage slide switch. The voltage it's set for should show on the switch and must match whatever voltage is available from your wall socket. In the US it's going to be 115 but in some uncivilized parts of the world it's 230. Unless someone has messed with it you don't need to fiddle with that switch. If by chance it is set wrong, only change it with the power cord disconnected and double check that it is actually wrong.

I have tried the things you suggested but does not change anything. I am still having the same issue. If it is in sleep mode how can I get it out of it and would it cause the power button not to light up? If so can you tell me how to get out of it?

Also I tried a different power cord even with no change in results.

looks like since i don't have the knowledge or courage to try this myself, I am either going to have to bite the bullet and either take it in to a place and pay for them to check it out or buy a new one for around the same price I paid for this one ( under 100 used) so if it's kaput then I'm not only out about 100 just to check it out but also the 100 to get another one. Thank you for giving me some ideas to at least check it out. I suspect it was from overheating because I never did hear the fan come on, What I can't understand is that it was working fine before the landlord had to shut the power off while he changed some wiring, then it all of a sudden stopped turning on. Thanks again for trying.

The most likely issue is a failed power supply.

that is the same thing that a computer person that repairs things is saying. What is a good price to pay for one? He is going to charge me 100 to install one. He also said if it is the motherboard he will just sell me a new one because it would be cheaper. What does a power supply cost usually for a new one

by making a 2nd phone call I can get the place i bought it from replace the power supply for 30 total. 15 for the power supply and 15 to install. I talked to him and he also agreed that it is the same thing. So excited, 30 vs 100 what do you think I'm going to do. Whoo hoo. Thanks for all your help.

Power supplies can vary widely in price and quality. You can't go strictly by the quoted price without knowing what power supply will be used.

Took my computer to a repair place that checked the power supply. It was good, turns out it was a mother board (ugh) and ended up just buying another used one that has been updated. 90 day warranty for me to see if it is going to be something I can get used to. It has everything my old one had on it. They brought it up in the store to be sure it has no problem coming on. Still only had to pay under 100 for the new one and they threw in a keyboard because my other one was so old I had the letters wore off. I can use it as a backup if something else happens to the "new" one.

We're glad you got it fixed. It's always good to have a spare computer (or two).
