Hardware problem troubleshoot.

Problem: overheating: which is a common problem mostly happens with laptops.

Firstly it makes your computer perform very slowly.

Secondly blue screens will appear like this on the picture:

Thirdly computer will start restarting and shutting down.

It happens because the CPU becomes overheated so the computer protects the CPU by shutting down otherwise it will melt.

it also sometimes makes a physical damage to the case and even cause burn to the user if it touches the body directly, as you see below:

How to fix it :

1-      Make sure the fan cable is plugged on mother board.

2-      Clean the fan and make sure u use the thermal paste (cooling liquid) because sometime the fan is working well but it doesn't receive all the heat so the CPU still overheated.

thermal paste :very high heat conductive paste that is used between two objects

3-      Change fan.

Software troubleshooting:-

problem: The Nvidia graphic card performance is weak and not smooth after format, especially in video games. Also the screen resolution is low.



solution:
1)  Go to the nvidia official site. click on drivers and search for the driver that matches your graphic card.

2)  Download and install the graphics driver and restart your system. Running graphic intensive applications    should be smoother since the graphic card is up to date.
