Hello my name is John and I will be assisting you today. I understand technology can be frustrating at times and hopefully together we can come up with a solution to your problem.
Usually if you get an all white or all blue screen it will state what driver down at the bottom that is causing the issue. In my experience it is usually the Graphics Driver is out of date or possibly corrupted.
Here is what Samsung Support Article states about the issue. When it comes to a Technician trying to figure out a problem we need to narrow it down to Software or Hardware. The only way to know is to try to eliminate that its a Software Issue. If you can get in to the system using safe mode you can try to update the Graphics Driver first.
Try to boot in to safe mode. Turn on the computer and tap the F8 key once a second till you see an advanded menu screen. Use your arrow keys to move and highlight to Safe Mode with Networking. Safe Mode can take a bit longer to boot to so be patient.
Once your in there you can go to http://www.samsung.com/us/support/owners/product/NP-RV720-A01US# and choose the Downloads and find your Graphics Adapter Driver and install it again. If your not sure which driver you have. Click Start button and type in the search Device Manager. Click on it when it comes up. Look by Graphics Adapters and click on the little arrow to the left. This will give you the name of the current graphics adapter you have installed on your computer.
Check out the article below. Start off with the Graphics Driver replacement first. If you cannot get in to the system at all then you will have to go for the Restore. Be careful this will erase anything you have on the system. It may or may not have a backup section where it will copy your data to a flash drive.
Bottom line if you try both these options and you still have the same problem then your more than likely looking at a hardware problem. Could be the LCD or LCD Cable. Only a more experienced Technician can diagnose this more but they will need to have it in their hands. Usually Samsung can give you some kind of estamate up front.
