Well I did a very stupid thing, I disconnected my PC while it was on(dumb me). Now it will not power on  This was my 2nd time doing this and guess I didn't learn my lesson the 1st time obviously. I know that I didn't mess up the motherboard or the power supply because when I got it fixed the first time the repair man didn't need to replace anything. I have no clue what he did to get it started again but I'd like to get some advise from any of you computer nerds here  I tried disconnecting the power supply from the motherboard and reconnecting it to see if it would reset it but that didn't work. 8 year old windows xp |

Disconnecting it while its on shouldn't cause it not to power on.
Do you have a multimeter? If so you can check if the power supply is still delivering current at the Molex connector that clips on the motherboard. Is there a fan? Check to see if it turns on - a good sign that the PSU is fine. Thereafter to other ventures to see if there's a 5V or 12V supply present on the power rail on the motherboard...

No lights? No spinning hard drive? Nothing? DVD drives won't open or close? If it is 'nothing' then I'd suspect the power supply - thats a hardware problem. If you mean it won't boot up "but it tries" etc then its a software problem.

If you mean it won't boot up "but it tries" etc then its a software problem. Yea absolutely nothing is turning on But if the power supply is bad than how did it get fixed the first time without replacing the power supply? I know I should probably take it back to the tech guy but wanted to see if there is anything I can try on my own before doing so. |

When you say disconnected, you just mean you pulled the plug out of the wall?
Maybe look for the obvious things... fuses... wall out let has issues... power strip is off.
I don't think thta it broke and then fixed itself the first time, it either didn't break... or the problem was intermittent.

You can try all the connections inside to make sure there are no loose wires. Other than that I still say the PSU is suspect.

(Two plugs - one big one and one smaller 4-6 socket plug) before it will turn on. After doing that and it still doesn't work, try touching the two jumper pins for the PS with a screwdriver to jumpstart |

My money is he forgot to plug in the second wire. If not - power supply/shorted out power cable.

is the power switch in the back turned off. I personally have done this. I disconnected and moved the pc and had bumped off the switch also by accident.

I would suggest, first checking all the connections, as above, and check the outlet, power strip or surge suppressor for power.
Then unplug the power cord from the back of the CPU.
Next, press the power on button with the CPU rocker power switch in the on position (if not sure do both positions)
This will let some of the capacitors discharge (sometimes the computer's state is held because of this [i.e. hibernation or sleep]).
Plug the CPU power cord back in, check the rocker power switch and try to power on.
Sometimes this will take two or three presses of the power switch (I usually try it with the rocker in both positions, because I don't want to go around back of the CPU, and I can't remember which position is which).

If you are indeed having hardware issues I would recommend replacing an 8 year old computer versus trial and error on what is wrong. If you have to take it to a repair man you will invest too much into a computer. At 8 years old you will likely be taking it back to him shortly. You can have a very nice build by a local builder for very inexpensive.
If you don't game you could spend some money on an SSD and experience real life. My new builds are so fast I restart for fun. MWahahahaha!

Yea so far I tried different power cords, different outlets, made sure everything was connected snug and even tried to jump start the psu with a paper clip. No luck
I was planning on replacing It anyways with a Mac mini but the PC has a lot of important files.

What do you use it for? If surfing the web and email, etc; forget a computer and get a nice iPad.

I doubt the hard drive is toast unless the PSU sent out a surge of current - and I've seen that happen but it is rare. To extract the files simply connect the drive to a working computer via an external connection and copy them to the new drive. Or use that drive in a new computer as a storage drive.
And a +1 for the SSD drives. I've been using a 128GB Intel SSD for my boot drive for a couple of years with no problems at all. With Win 7 I can get from turn-it-on to the desktop and windows fully loaded in 20 seconds. I use a 6 core AMD that is very fast. With an SSD you do not defrag the hard drive - EVER! All it does is wear it out prematurely. They are fast - quiet - and for the most part much more reliable. Buy a good brand - Intel is one of the better brands.

Because I've made that mistake tons of time and only plugged in the big rectangular plug. |

I was planning on replacing It anyways with a Mac mini Are you set on the Mac Mini? I love my Iphone and Ipod, but the performance to price on Mac computer stuff is just god awful. The only reason I could justify the Mac Mini is if space was an issue then it is pretty hard to beat. Which Mac Mini are you looking at? I might be able to get you a discount at the apple store here in Austin, Texas. |
