I've had this problem for a while now, I have a Samsung np300 something (can't remember the full model number)
It is always rebooting before getting into any post start-up or bios options.
I have tried a number of things to such as disconnecting all non critical hardware, such as wireless card, changed ram, disconnected everything even including the screen.
When i take out the ram it seems to stay online but of course I can't see what is on the screen but the lights and fan continue to work

Can anyone help with this or advise please?

Thanks
 
Note: If this problem started after an update (or system reinstall), please make sure the laptop is not connected to the internet in any way before you use the following instructions.

Try the following...

1. Power off the laptop.
2. Power on the laptop.
3. As soon as you see the rotating loading circle, press and hold the Power Button until the computer shuts off.
4. Repeat this process a few times until you see the "Preparing Automatic Repair" screen.
5. Now you want to let the laptop boot to the "Automatic Repair" screen.
6. Click "Advanced Options" and then select "Troubleshoot".
7. Here you want to select "Refresh your PC", if you do not wish to erase data, or "Reset your PC" to erase all data and restore your system.
8. From here just follow the screen instructions until the recovery is completed.

NOTE: You will need to get into the "Advanced Options" in order to get the "Refresh Option". This choice will keep your data, but any programs installed will be lost.

Do not do a "Reset" as that will wipe all data you have on the laptop.


Another version of this is the following...

1. Power off the laptop.
2. Power on the laptop.
3. When screen turns black, hit F10 and ALT repeatedly until the computer shuts off.
4. You shouTo fix the computer you should choose the second option listed.
5. When the next screen loads, choose the option "Reset Device".
6. Now choose which ever type of reset you wish.
7. Your coputer should now restore itself to "Factory Settings".

NOTE: If you get a message saying "Error Resetting Device", then you should have the computer looked at by the manufacturer (if still under warranty) or by a tech.

I'm not sure when it started, I don't recall it bring after am update, I've checked a few things today it seems to be motherboard related, however I have taken out the ram and all the lights stay on, I replaced the ram with known working ram and it had the same reboot problem, I tried the "broken" ram in another machine and it worked fine.

I don't even get passed the Samsung loading screen, I tried to stick a bootable usb to boot into this but again looped 2 seconds after turn on.

Do you have any other suggestions before buying a new board?
