Hi MazenLasheen,

I apologize for the inconvenience.

I recommend you to run diagnostics on the hardware components of the system. To run diagnostics restart the system and at the Dell logo tap the F12 key every two seconds. This will start the One-time boot menu. Using arrow keys select ‘Diagnostics’ and hit enter. This will run diagnostics on the hardware components of the system which may take around 5 minutes. Please reply to this post in case of any error message.

You have mentioned in the post that you tried to run system rate. I would like to know if it is run by navigating to system properties as shown in the picture below:

Please provide the system model and the operating system to assist you further.

Sujtha thanks for replay .. i did what u 've told me to do and i ran the normal and the thoroughly test and i found out that there is nothing wrong with the hardware components .. do u knw why the problem is exist ? the systen model is Inspiron N5110 .. Operation System ? Windows 7 64x ?

Hi MazenLasheen,

It is good that diagnostics passed. This indicates that all the hardware components are working as designed.

I would like to know if you experience the system overheating before it shuts down while playing games.

I recommend you to flash BIOS and update Cipset and Video drivers from the following links:

BIOS: http://dell.to/13EB5VX

Note: While flashing BIOS connect the Ac adapter and make sure the battery has minimum 15% charge as this needs uninterrupted power supply. Do not use the system till it restarts and comes up to the desktop.

Chipset: http://dell.to/15wLWjk 

Intel Graphics: http://dell.to/15wLWjk

Above provided link for video driver is for Intel Graphics card. In case the system has Nvidia or AMD video card, I request you to download the relevant driver from the link below:

http://dell.to/15wLWjk

Select the Operating system and click on Video which will list all the Video drivers for this system. Restart the system after each driver update.

Let me know the status after all the drivers update.

Sujatha .. thnx for the quick reply.. i did what u've told me to do again .. but there is a problem that i cant fix.. i downloaded the Bios Flash and the chipset and the Intel HD sources .. i updated the Chipset and the VideoCard .. but the problem is that i cant flash the bios .. it gives me error msg like that

Hi MazenLasheen,

You may ignore this error message. As the system has up-to-date BIOS, this error message is popping up.
Let me know about the system performance after chipset and graphic driver update.
