Re: MY HP M8100N shuts down after rebooting

The quality of ECS can be spotty.  I have an ECS NF4 board that's very reliable but have seen many that go to the PC graveyard in two years.

Re: MY HP M8100N shuts down after rebooting

Dang!  GRR!!  Three days out and I'm back to the same thing.  It shuts down again upon starting it up.  It didn't even start up and make it to the desktop last night.  Next we are going to test the ram.  Any other ideas are appreciated.

Re: MY HP M8100N shuts down after rebooting

I replaced the motherboard on my HP M8100N and after about 3 days my pc won't boot.  This time it's different.  Seems like there is some residual power but when I press the start button it sounds like a drive is spinning for a few seconds, and then everything shuts off.  My webcam stayed on, at least the light on it did.  Do you think this could now be a power supply issue?  Going crazy....

If you're sure that the PSU, RAM, and MB are good, then the OS must be at fault.  Per my previous post, you want to disconnect the hard drive to eliminate software issue.  Next step is to test with a quality PSU.  Once you can boot into windows, run Memtest86 to test RAM.

 

Intermittent error is very difficult for a novice person to isolate.  A pro will usually take the board outside the case and test with known good components (PSU, RAM, and windows).  If the problem persists, then the MB is defective.

Beth,

 

It could be many things - but as to memory - your machine can operate with a single memory stick - try using one at a time.  I am sure it will run quite slowly - but it should be enough for you to verify if one of the memory modules is at fault.

 

As to the power supply - it could be that - the only way to really verify is to swap out the power supply...

 

If the power switch were to stick on (its normally a make/break connection when you push it) - the system could be interpreting it as the signal to shut the system down.   Normally - if a PC were to hang, holding down the power switch for 5 seconds or so shuts it down.  A flaky power switch could simulate that.
