Do not worry if your computer has crashed. There is very good chance that the data is there and intact. The first thing to do is to start an investigation. Consider why the computer has crashed. Was there a hardware fault or a software fault because of a virus. A computer crashing can be due to different things. They sometimes occur randomly and sometimes, they can happen when there is something specific that has happened, for example, installing a driver.
Check to make sure the computer is not hot. This is the first thing to worry about. If the crash happened on a laptop, touch the bottom surface to check the temperature.
If there is a place on the surface of the laptop that is very hot, then you have found the cause of the crash. Usually, you will find this hot area is where the laptop fan and heatsink are. If the surface temperature is normal, open the laptop and power it on. Usually, it will power on again without any problems. Sometimes, Windows will scan the hard drive for errors. You can leave it to scan for errors but, just be sure there is no lethal damage made.
Usually, the Windows hard disk scanner does not provide understandable information, so it is best to just leave it to finish the job.
If the computer does not boot to the desktop screen, use the Safe Mode. When you power the computer on, after a moment, press the F8 button. You will see a menu and when you see this, choose the Safe Mode.
When you are able to boot to the desktop, a good thing to remember is to back up the data. Take any external data storage and transfer all your important files there. It is better to do this in Safe Mode because viruses and Safe Mode has better stability and will not crash suddenly.
Save your data not because it can be lost at home, but because it can be lost when you take your computer in for a repair. This has happened to some customers already as they told us they didn't need the data. As it turned out later, the data was there and it was important.
If you are capable to deal with the computer software, there is a good tool to use in order to check the hard drives health. This is the GSmartControl tool. It will tell you much more than someone working in a computer repair shop. Download, install it, and get the data from it. How to interpret the data is explained separately here.
There is also a test tool for memory. But, memory faults are rare and there is a very small chance that there is something wrong. Irregardless, download the test tool, burn it to a CD, and conduct the test to be sure.
If windows shows a blue screen during the crash, write down the crash code and put it into a search engine. Mention your computer model as well since sometimes, blue screens are specific not only to a specific Windows version, but also to a specific laptop model.
If the computer refuses to boot, then get an external USB to SATA/IDE adaptor, take the hard drive out, and back up the data. To take the hard drive out is an easy task. This process will be a little bit harder on desktops and on old laptop computers. You just need a screwdriver and a how-to guide, which can be found on YouTube.
