Just started yesterday and today it is even worse. I tried to play a movie from live streaming and everything seems to be fine but when I full-screen it freazes up, gets really pixelated and the only recourse I have is to shut my computer down. At the moment my screen is very really weird, the colour is off, pixels are large but everything else seems to be running fine! What the hell is wrong with my computer? It's only 5 months old and I have never encountered this before. Could it be my NVIDIA graphics card (I have alerady checked for updates for my computer and windows seems up to date.

However, you may have a worse problem. White screen issues are often caused by bad cabling, in which case you (or a certified technician) would have to open your laptop's bezel and check the wiring for the screen.
Third possibility is ensuring your power options are set to NOT turn off the screen after any amount of time. Sometimes Windows doesn't recognize that something as simple as a movie is currently playing, so it tries to hibernate, and that causes the issue.
It is graphics related. The graphics card is not compatible with Minecraft, from what I can tell. I believe the Toshiba is running an Intel integrated card and Minecraft is looking for an ATI or NVIDIA.
Either bad RAM, overheated CPU, or a bad (or overheated) video card will cause this. Usually it's bad RAM.
I'm assuming you're running Windows 7. To test RAM with windows 7:
Method 1:From Windows 7 Start Menu
•Click the Windows 7 Start button, type memory, and click on Windows Memory Diagnostic •When the Windows Memory Diagnostic screen loads, click Restart now and check for problems •You computer will restart •The memory diagnostic will run and may take some time •Windows will restart and report any errors to you
Method 2: From Windows 7 Control Panel
•Click the Windows 7 Start button. •Select Control Panel •Click the System and Maintenance icon •Select Administrative Tools •Then, click the Memory Diagnostics Tool icon. •Click the option to restart your computer now and run the memory diagnostics test or to schedule the memory diagnostic test to run at your next reboot.
Method 3: From Windows 7 Command Prompt
•Click the Windows 7 Start button. •Type cmd in the Start Menu's search box. •Right-click cmd.exe in the search results and then select Run as administrator. •Type mdsched.exe in the command prompt and then press enter. •Click the option to restart your computer now and run the memory diagnostics test or to schedule the memory diagnostic test to run at your next reboot.
Method 4: From The Windows Boot Manager
•Restart your computer. •Start pressing F8 on your keyboard. •This will open advanced boot options screen. •Click Esc on your keyboard while you're in the advanced boot options screen. •You'll be taken to the Windows Boot Manager screen. •Press Tab on your keyboard to move to the Tools section of the boot manager screen and then press enter to start the Memory Diagnostics.

I would not start with the motherboard right away. Try updating your drivers first. Here is a link for Nvidia drivers. Then try replacing the graphics card if updating the driver does not work. Motherboards can be expensive to replace, even if the part is not costly the labor can be.
You will need to locate the appropriate driver for your card and operating system, download it, and run it to install it.
It is a knwon issue with the VGNAR100, 200, 300 series Computer that the NVIDIA Card shiped with the Computer is malfunctioning.
In July 2008, NVIDIA announced that some notebook computers with NVIDIA
graphic processors manufactured with a certain material set were failing
in the field at a higher than normal rate. Since that announcement,
Sony, in cooperation with NVIDIA, has been looking into any possible
effect to VAIO® notebooks with NVIDIA graphic processors. Until recently
we had not identified any VAIO models that were affected by this issue.
If your screnn is not showing up anything, even the BIOS screen while booting up. Then it could have damaged the Graphics card. You'll have to mostly replace *********** board. Your vendor can provide you a replacement price instead of buying a brand new one.
To avoid these scenerios of graphics card buring out, i would suggest to use the laptop keeping on a flat surface, especially not on pillows, bed and lap. Also dont use the laptop always connected to the power adapted. Connect only when the battery goes down. This will increase the battery life too.
Can you bootup in Safe Mode?
Press F8 when you bootup.
Then select LAST KNOWN GOOD CONFIGURATION. then check the Device Manager to see if the Video driver is OK and enabled. If OK then shut down and bootup again to see if it boots up normally.
If this doesn't work select SAFE MODE instead of Last Known ......
When Windows starts then select a Restore Point prior to the installation of the driver update and when it boots up again with luck it will be OK. The graphic card update maybe causing the problem.
Go to NVIDIA control panel (Right Click on Windows Desktop) Set and check ALL your Paramaters to match with your Hardware reduce resolution (if required) to get the quality you ask for. If you use CRT screen be aware of magnetic fields (Speakers, UPS, motors) interferences: try moving screen or disturbances. Pls let me know if working.
Whats the Operating System? XP? Have you downloaded & installed an updated driver? Sometimes the software driver corrupts & you should install the newest version from the website.
If you can get an external monitor, plug it into the external monitor port.. (most laptops have one) There will be a keyboard combination to switch between your laptop screen & the external monitor. This will help diagnose the fault. What is the results of the above? Rgds,
