Power Problem Netvista 6794

[letnes]

I have a Netvista that will not stay on. When you turn it on it switches off after a few minutes. Sometimes it will boot all the way and stay on for an hour or so.

I have replaced the power supply, reseated all the stuff connected to the motherboard and still the same problem. The only way to get it to stay on is to remove the 12V power connector from the motherboard, then it will stay on for hours but the machine does not boot with this connection removed.

Thanks

Do NOT remove ANY power connections from ANYTHING in your computer while it is running EVER! You're just asking to damage components or start a fire...

I hope I did not give the impression that I removed the 12V connector while the machine was on. I know enough about messing up motherboards to ground myself and turn off the computer before I do anything to it.
