Hello and welcome to Bleepingcomputer.
I take it your computer boots Okay in safe-mode and if this is correct, then we have two possibilities here.
One is your driver, being that video drivers do not load while booting into safe mode could mean your driver is either the wrong one, or the driver is a corrupted version.
The second possibility is your laptop has a cooling problem. If either the CPU or integrated video chip is getting too warm for safe operation, the computer will run unstable and either freeze up, restart or shut down.
Can I ask you if you have ever tried blowing this laptop out with a can of compressed air?
If it has been a while since you have done this, I would suggest you give this a try, because when you run games that use a lot of processing power, this causes the CPU to process faster and generates more heat, more heat causes system instability to be possible and things start freezing up, in many cases, the video screen shows the first signs of this instability.
So it may not be your drivers that are at fault here, it could be heat related.
I also see where you said an external monitor works, but your intergrated laptop video screen does not, I need a little bit more information here, does your laptop's built-in monitor work at all?
