"The IDE cable is upside down or off by a row or pin."

Sorry if this doesn't apply, but I don't much to work with so I resorted to my stack of envelopes for an answer.

why would this happen without making any changes internally?

Because a component failed.

Since your machine is broken, you have to either open it to see what you can see or get it fixed. Just flipping the power on and off will likely accelerate the damage to more parts.

In the words of my friends at Guiness "Brilliant" Are you always full of such knowledge? Being condescending is not what help forums are for. Having 52,000 posts does not make you the ruler of the roost it just means you have no other life than to peruse this forum. But I guess that keeps you off the vile sites or does it? I don't need a freaking computer geek being sarcastic when all i was seeking was meaningful imput.

you have a hardware failure that is overlosading the power supply at turn on and the overcurrent circuits are shutting the power supply down. What are the chances that your old supplies can have a capacity to provide more power???

I think that you missed the point of Robert's reply. You TOTALLY failed to provide the information requested in red regarding what info you should supply so that we may possibly be able to help you.

Robert responds to so many posts that every now and then he gets frustrated by people not providing the requested info. Thus I believe his reply had a little sarcasm in it. LOL

You may have an overheating CPU

that's causing the shutdown. A second is a little short UNLESS your heatsink has become decoupled from the CPU. If that has happened it'll shutdown very fast. The CPU gets hot virtually instantly.

should I try another heatsink? the fan starts to turn when powered on or should I try reattaching this one?

from the HSF, be sure to clean the old thermal compound off both surfaces fully. Then apply a very thin coating of fresh thermal compound before remounting.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
