Your laptop cannot handle the game. It's too intense.

More in-depth;
Your graphics are Integrated Graphics.
It is Intel HD Graphics,

http://en.wikipedia.org/wiki/Intel_HD_Graphics

Uses an Intel Pentium P6200 processor,

http://en.wikipedia.org/wiki/List_of_Intel_Pentium_microprocessors#.22Arrandale.22_.2832_nm.29

That processor is based on the Arrandale Core.
(32 NanoMeter architecture)

Means It is the first Intel HD Graphics. 6 Execution Units.

Be lucky if it could fight it's way out of a wet paper bag; graphics performance speaking.

Also if you have never had your laptop partially disassembled for cleaning, (Fan/finned Heatsink), I would advise you to do so, and avoid a lot of trouble in the future. (Maybe near future)

Do it yourself? Sure IMHO. You, though, will have to be the judge,

ESD wrist strap, and it's alligator clip attached to a good ground source.
Average cost is $3 to $6.
One example,

http://www.radioshack.com/product/index.jsp?productId=2103245

Set a large metal serving tray (Unpainted), on the table you're working on, and connect to it.
Or a large metal knickknack. (Unpainted)

Use a mutli-compartment container for the various screws you will remove. Label each compartment for the area the screw/s come out of.
SOME screws look VERY similar to other screws.
Advise do NOT mix them up!

Use Q-tips, a soft small brush, (Makeup brush?), and a can of compressed air for computers.

Want to see how bad it can get, and you won't know it until you see it?

SOURCE: Suddenly my Toshiba Satellite A205 laptop died. No power.

First, check your power supply (the adapter). Is it putting out the required voltage to charge the battery?
If not, then you might have a dead battery and no way to charge it.
If the power supply is working and when you turn on the computer you get no lights, then you're probably looking at a new motherboard.
If you get startup lights and hear the fan, then it's getting power and you might have a video problem. But it sounds like, from what you wrote, there is no activity at all when you try to start it. That would be the power circuit on the motherboard, most likely.

you probably don't need a new screen it's probably your screen inverter that's going. It's just a small strip at the bottom of the screen wjth a little circuit board. If you google screen inverter and the make and model of your laptop you'll see what I mean.

How to solve Toshiba satellite L645 From black screen ?


You may have a faulty inverter, it supplies high voltage to the CCFL lamp.
If your laptop appears to boot up and the hard disk LED flashes, then the problem is probably a back light fault. This can be a faulty inverter or a faulty CCFL lamp.

Black screen


The most common problem is that your laptop is overheating. Second most common, damaged operating system.

Try removing any dust from the laptop's processor heatsink. If you are uncomfortable doing this, your local computer shop should be able to help.

Display Problem Black turns Red


sounds like you have a loose connection ....either into the screen or into the motherboard....the connection between board and screen runs through the hinge brackets and often comes loose after machine has been opened and closed a lot.....need to be comfortable opening up laptops to check the cables as it can be tricky to get to the back of the screen where the end of the ribbon cable is..
