Re: COMPUTER SHUTS DOWN
If your problem starts after enable your ethernet connection means it can be a network adapter (Ethernet card) problem or the cable problem.
When there is Hardware failure or malfunction in any device windows use to get restart - its a safety procedure that windows itself checking to correct the issue.
Check your network cable (ENET cord) for any damages or short circut with the help of a cable tester or connecting this same cable to a networked pc if its ok then you can check your network card driver and test the network card with ping command - to do so
Doing network card test
go to RUN -> type cmd then enter when u get the prompt type 127.0.0.1 if it reply three times then your card is ok otherwise try to replace it wil another pci network card.
Go to Device Manager in that go to Network adapters and right click on ur Lan card go to properties, in that go to Power management and uncheck the box which say Allow the computer to turn off this device to save power

You will have to get your power button unstuck. I do not know what type of button you have but if you would like to at least get your PC on without it instantly turning off, you can remove the power switch connector from the motherboard. You will eventually need to have the switch unstuck, or replaced though.
When does it shut itself off? Is this happening time you press the power button and during the boot cycle it shuts off without completing the boot to windows? If it shuts down after you've worked on it for a while it could be that it is running hot. If you let it sit a while to cool off then press the power button, if it completes the boot cycle and allows you to work it is definitely running hot. Normally when they run hot if you immediately try to reboot, it will fail. If you let it cool off it will boot successfully. Computers run hot because of a fan not working, dust clogging the fan vents or the Thermal Paste around the CPU and Heat Sink has become hard or too thin to keep the unit cool. If it's not running hot you might have a power supply or motherboard issue. Try removing the power cord and press and hold the Power Button for 30 seconds to release any Static Buildup. Then plug the power cord back in and try to reboot.
it sounds like your motherboard is shutting itself off to protect itself from overheating or some other system failure. you should verify all your fans are running at the correct speed. if it seems like everything is running fine, you can probably turn that off in bios. obviously if there is something wrong with the fans, then you need to replace them. Another options is maybe the processor is getting too hot which is why it's shutting down. open the case and remove the heat sync from the board so you can see the processor. clean the thermal paste off the processor and apply a new generous layer. put the heat sync back on and then try and restart. make sure before you do ANY of this you unplug the computer! good luck and let me know if it works!
I had this problem the other day... I held down the power button until the computer shut down. Then, pressed the power button to start it up again. Windows started with out any problems so, once it got up and running, i did a "proper"restart and all is well.
Unplug the computer and open the case. Take a picture of the cards in the slots, and then remove all of them except the videocard (the cable that connects to your screen) if you have one that isnt built into the motherboard (be sure to label the connectors going to the cards if you're unsure of what they are) and then power the computer back up.
If it works fine one of the cards is bad. (If it dosent, skip down 1 paragraph) Turn the computer back off and unplug it, plug 1 card in and turn it back on. If it works, shut down and do the same for the next card. Keep going until you find the card that is killing it.
If it still dosent work with the cards out, it could be the power supply or something on the motherboard. Unplug the PC again and turn it on without plugging it in, this will drain the caps on the board. Holding the computer case with one hand (or use a ground strap) remove the memory from the sockets. Plug the computer back in and turn it on again (dont reach inside, fans and wires that are powered up). If it still does the same thing, it's the motherboard/cpu, if it beeps at you, it's the power supply.
More information would help to resolve this issue.
Are you shutting down by selecting Start and shutdown or have you tried pushing the power button on push (not holding the power button)?
Try this: Press and hold the power button in solidly for about 10 seconds. If it shuts down before you get to 10 just let off the power button. This should work, but may not solve the problem.
If you reboot it and still can not shut down from Windows, hold power button until it shuts down, unplug the power cord and disconnect everything from the computer other than the keyboard, mouse and monitor. With the power plug still unplugged, hold the power button in for about 15 seconds (this resets the power supply and can clear a corrupt BIOS).
Reconnect power and after booting, see if you can shut down from Windows.
If still no go, click Start, Programs, Accessories, System tools and select System Restore.
Follow the prompts and select a bold date back to a time before you had problems shutting down. That should do the trick.
Let me know if you get it fixed or if you need more advice.
