Laptop computer problems can cause by internal disorders of the physical connectors. The common victims are network or modem ports, which may be detached within the case or the breaking of the power connector solder joint of the board. Such problems are very dangerous because here you need to open up the body of the notebook for soldering. Be careful to use a decent solder sucker for quick clean up.
Laptop problems are often caused by virus attacks. In this case they behave very strangely. One common symptom is the screen display goes off though the laptop is running. This can be due to graphic display driver files affected by virus or sometimes deleted by anti virus considering it to be a strange file. Re-starting the laptop in Safe Mode and re-installing the display drivers will repair this problem.
If you are not tech savvy, my personal advice is to hire a professional technician for Laptop computer repair unless it is software related problem. It is always better if you can contact s Laptop Repair Company authorized by the Laptop manufacturer.

Repair laptop display problems
If there is complete display failure, first of all check the status of the power. If you were able to hear the fan of your laptop and now it isn’t, that means it’s a main board or power failure, not a video failure.
Another common practice in laptop computer repair is to connect a normal computer monitor with a standard VGA connector, if your laptop does not light up the external monitor means either the internal video adapter or the motherboard has failed. In case the external monitor is working then your laptop video subsystem has a problem and need to investigate further.
If there is a display problem in your laptop computer and the number of dead spots or columns or whole row increases slowly on the screen, it indicates that the assembly of actual LCD is bad. In the same way, if the screen flickers it is probably the failure of backlight or inverter.

How to solve low memory problems?
Normally this warning message shows when you run many programs same time than the RAM installed on your computer is designed to support. Your can solve this problem by increasing the system paging file size also called as virtual memory. Using this virtual memory windows moving information to and from the paging file for fast processing. This will free up enough RAM for other programs to run properly.
To increase the system page file follow the give path:
Control Panel > System > Advanced > Click on Settings (Under Performance) > Advanced > Change
Here under Drive (Volume label), you have option to select any of your hard disk drive, but the best choice is, select any drive other than C drive for virtual memory.
Set the double Initial & Maximum Size of your Virtual Memory. Here set initial size 700 MB and maximum size up to 1000MB; you can change this size according to the free space available on your hard drive.
