When you plug in the power supply in starts up and can't shut down

Good day,
The problem you describe is probably due to a faulty power supply.
The four pin connector which you unplugged supplies power to the CPU, which means you will not be able to get a display with it plugged out, as there will be no power to your CPU.
The fact that the PC does not shut down when removing the 4 pin connector strengthens the evidence that your power supply is faulty. By removing the 4 pin connector you are reducing the power required from the power supply to the point where it is not 'overloaded' enough to switch off.
You can test this by plugging in the 4 pin CPU power connector, then unplugging something else, such as the DVD writer.
Then switch on your PC and see if it still shuts down.
If it remains on then the cause of your problem is definitely the power supply.
Replace the power supply and make sure it has a wattage rating of 400 watts or more. These power supplies are relatively cheap, and should be available at your local PC store for about $15.
Best wishes,
Graeme.

hi, happens on my msi, notebook too. if you have 2 graphics cards and one is nvdia. disable the nvdia card in device manager. there has been problems with this card causing shut downs.

It has gone faulty and is causing a power overload and this causes the PC to shut down, so it will not be damaged. Either the power supply Inside the DVD is faulty or the DVD, is.

hi , by your description i would say the relay in your power supply is deffective , its not a cost effective repair , so change the power supply

hope this helps

or take your out REMEMBER where plugs go and buy a new one cheap

does it run with the power cord plugged in? if so your batterys dead, otherwise harddrive/bios/motherboard fault? is your power supply charging the battery?

make sure that the switch on the power supply is set on (the- side)
remove power cord, turn supply off then on and plug it back up and try it again. Power supply could be bad.

Hi jderek4, try this. locate the toggle switch on the back of the power supply. Just find it do not flip it.
Plug the PSU's power cord into the PC. Just as you got a good connection & the PC begains to power up move the toggle switch to it's other position. The PC should power off that very second.
If the PC does not shut off than the PSU is bad. If it did shut down wait a few seconds. Press the cases power on button. The PC should start to boot up. Let it finish loading. Click the start button & choose to shut down windows. The PC should shut off.
Yes? If not than your back to (bad power supply). Swap it out.
