Samsung NP470R5E BIOS sticks on Splash Screen

Hi

I have been working on an issue on my daughter's Samsung NP470R5E laptop for more than a month, but I am now hitting my head against a brick wall. The problem was that it was sticking on the Samsung splash screen on boot. It would not look at the hard drive and, as it was Windows 8, eventually I thought it might be easier to buy a Win 10 licence and install that I reformatted the hard drive accordingly. .

I created the installation media from the Microsoft site onto a DVD but, although I could enter BIOS via F2 and point it at the external DVD drive, it did nothing, no errors or beeps etc, just stuck on splash screen or a blank screen. I had disabled Fast Boot and enabled CSM and UEFI OS prior to this.

I next tried to create installation media straight on to a USB drive via the Microsoft site (I actually tried 2 different drives) but, although the BIOS could see the USB drives it would not boot but again stuck on splash/blank screen with no indications.

I also used Rufus to create the WIndows installation onto a USB drive from the ISO file I downloaded but same result. Similarly I used Rufus to create a Free DOS bootable USB drive but same again.

When creating USB media I have tried all formatting options FAT32, NTFS etc along with different block sizes etc. The frustration is that the system consistently sees the USB drive, DVD drive etc and allows me to select it to boot from, but never appears to read anything off it, never getting past a blank/splash screen with no error messages. I never see any POST messages even with fast boot disabled.

I have seen suggestions on forums regarding temporarily disabling the main battery and also disconnecting the CMOS battery to lose the current settings and go back to defaults. I did this which seemed to work as the date and time in BIOS went back to 2009. But no change to the boot issues.

The BIOS in the machine is Aptio 2012 American Megatrends version P13RAN. I cannot see a way to re-install or update this without a working OS, be that Windows or DOS.

So I am running out of ideas and wondered if anybody had any suggestions?

Thanks

Hi, and welcome to NBR.
It is hanging on the splash screen meaning it is hanging on initializing something. My first suggestion is to disable the fast posting in bios so instead of seeing the splash screen it displays the posting information, if this option is available. I have seen many hard drives that will related their drive data to bios but refuse proper spin up and post. It could be other hardware as well too..

 

Hi TANWare

Thanks for getting back. I had disabled Fast Boot in the above tests but there are never any POST messages, errors or beeps. The strange thing is everything looks fine in the BIOS screens - it show the processor, memory, attached USB drives (it picks up and displays different USB drives and I can see the manufacturer of each in the Boot options section). Everything saves correctly when I tap F10.

It is at that point when it sticks on the splash screen or a blank screen.

I am not sure if it could be a hardware/motherboard type issue or could it just be the BIOS? If it is BIOS is there anyway to flash it without having a working OS, be that Windows or DOS?

Any suggestions appreciated.

Thanks

Brian
