Sounds like your CPU may be overheating after playing games for a long time and shutting itself off to prevent damage.
Make sure all the laptops vents are clear

If you can, download Combofix, Vundofix, smitfraudfix, and malewarebytes.

Boot the computer in Safemode, and then run each program, one at a time of course.

If this doesn't fix the problem, then it will at least verify that it's not a virus related issue.

re instal ur windows

First conclusion: This is not a software fixable problem. If your notebook is still in warranty, I suggest you to RMA it. No doubt somethings broken.

This can be caused by system file error or your CPU is over heated. I suggest you to have a system check first To check and repair system file error do the following
Right Click on the system disk (c: drive) then Properties > Tools > Errors checking Check now > Tick on "Automatically fix file system error
It will prompt you to schedule the check next time you restart. click YES then restart and let the system have the checking
If this doesnt fix please tell me
Best regards 

hi,
is the cd/dvd working now after removing upper and lower filters, if it is that is good,
when does your computer freeze can you associate it with some activity that you are doing on it,
does it give any error when it freezes any blue screen error

when you deleted upper and lower filters did the notebook started to freeze right after that or it worked fine for some time,

try restarting your system in safe mode and see if it freezes there
to go into safe mode
restart your system> at gateway logo > start tapping F8 > in this menu select safe mode and try using it in safe mode

tell me what happens so that i can help you further

I can fix it for you. You have to have it repair by a PC technican. I am one . This is a problem with the operating system. A file has been currupted. Where abouts do you live?
