Bluescreen, Bluescreen everywhere! HELP!

I've been trough HELL trying to figure out what's going on with my laptop (Qosmio X770-137 harman/kardon)

Here's a (short) list of the different bluescreens i've had.

* MEMORY_MANAGEMENT ntoskrnl.exe
* SYSTEM_SERVICE_EXCEPTION dxgmms1.sys
* KMODE_EXCEPTION_NOT_HANDELED ntoskrnl.exe
* DRIVER_IRQL_NOT_LESS_OR_EQUAL mouclass.sys and wdf01000.sys
* NTFS_FILE_STSTEM ntfs.sys

A common place for any of the bluescreens to appear is;

* watching videos online, mostly Blip.

* Some games: Kerbal Space Program, Minecraft, Rollercoaster Tycoon 3.
- Some games that don't make me bluescreen: Super Meat Boy, Black Ops 2, Duke Nukem 3D.


Things i've tried to do to fix.

* Memtest (everything OKAY).
* CD Re-install.
* Updated BIOS.
* Updated every driver listed on this laptops THOSIBA site.


I am really frustrated, I really hope someone out there can help me.

No one can help?

I can add a new bluescreen to the mix

*SYSTEM_THREAD_EXCEPTION_NOT_HANDELED_M ntoskrnl.exe

aaaand another one

* PAGE_FAULT_IN_NONPAGED_AREA usbxhci.sys

You should try to install windows 7 and use it for a while, just to be sure, that the problem is in windows 8 or in hardware.
Plus i googled about few of your bsods, it appears, your ram might be corrupted, so :
1) if your laptop still has a warranty, use must use it, but if it is expired, then :
2) if your laptop has multiple ram modules, then you should try to use your laptop for a while with only one module of ram at time, this is to check if all ram modules are corrupted, or just one of them.
3) if you have any options, you can try to remove your ram and insert new modules of ram, maybe your some of your friends have laptops too and can lend to you their ram for a little bit.
But its just a posibility, so when you will have some free time, you can start checking from new windows 7 to ram.
