Greenish Distorted Screen after Reboot

Hi,

Problem:

I've had the following problem with my Samsung NP550P7C-S05UK (see below for details) for quite some time now. Whenever I restart (or properly shut down, start again at a later point) the device, the laptop screen appears in a greenish colour and is stretched in the horizontal direction with only around 3/4 of it being visible. The system also appears to be a lot slower when the problem occurs. It does not occur after putting the laptop to sleep mode. If I connect a secondary screen, the appearance on that screen is normal.

Temporary Solution:

I can solve the issue temporarily by removing both the charger and the battery, put them back in again and then starting the computer. This sometimes requires several attempts. Sometimes a system restore has to be performed.

Solution Attempts:

Nothing of the following has solved/improved the situation:

• Driver Update
• Reinstallation of Windows 10
• Anti-Malware Scan

Laptop Details:

• OS Version: Microsoft Windows 10 Home, 64 bit
• Processor: Intel(R) Core(TM) i7-3630QM CPU @ 2.40GHz, Intel64 Family 6 Model 58 Stepping 9
• Processor Count: 8
• RAM: 8079 Mb
• Graphics Card: NVIDIA GeForce GT 650M, -2048 Mb
• Hard Drives: C: 905 GB (657 GB Free);
• Motherboard: SAMSUNG ELECTRONICS CO., LTD., NP550P7C-S05UK

It would be great if you could offer some suggestions regarding this problem. Do you need some further information about my system?

Many thanks in advance!
