Your computer shuts down for no reason randomly, with no error message, no blue screen? If it happens too frequently, you have to troubleshoot the whole PC for any potential errors and correct them as soon as possible. If ignore or delayed in correcting the issues, then there is a possibility for the computer to crash forever.
The first cause for why a computer shuts down for no reason should be that the computer is too hot. We know that computer components are more powerful than ever, however a piece of silicon hardware can produce an enormous amount of heat. This is the most common cause for random computer shutdowns. For this concern, when seeing your computer fan clogged with cake like dust, you should clean it timely to prevent a computer crash due to overheating.
Secondly, make sure the PC is always well protected with an updated anti-virus/spyware program. As we all know that virus will always create garbage in the PC registry, automatically load some unnecessary services and things that will reduce the PC performance and eventually bring in a random computer shutdown. So it is necessary to always update the anti-virus installed on your computer to make sure that you are always using the latest virus database. Then, regularly detect and remove any threat that inside on your computer.
The third reasons for why the computer shuts down for no reason is all to do with the number of programs you have inside. It is quite common for you to install some certain programs onto the PC to accomplish some PC requests. However, the more programs you installed, the slower the computer will be. When there is no enough RAM or system resource for you to finish your giving orders, the computer will stop responding. To ensure the smooth PC running without a shutdown at any time, besides turning off some unwanted startup items, it is best that you can check and uninstall the unwanted programs from the PC.
By the way, If the two above solutions do not work, you can use the Startup Repair option in the Windows Recovery Environment to repair the BCD store. This may repair some missing/corrupted system files, which may lead to a random PC shutdown. To do this, carefully follow the steps here:
*Insert your Windows installation disc in the disc drive, and then start the computer.
*Press any key to continue when you are prompted.
*Select a language, a time, a currency as prompted, and a keyboard or another input method, and then click Next.
*Then, you should select Repair your computer.
*Select the operating system which you want to repair, and then click Next.
*Click Startup Repair within the System Recovery Options dialog box.
*When the repair finishes, restart your computer to see whether you can start it correctly without a Windows Boot Manager Error message.
After the above steps, you still need to check and repair Windows registry errors. If you know something about the computer, I believe you know that registry is very important for the proper running of a computer and all programs, and should be good taken care of. If you delete a necessary file improperly, some errors like Application Not Found and computer error code 0X0000034 will happen.
Hence, to safely fix registry error and get rid of random PC shutdowns you’d better rely on a registry cleaner tool. It will thoroughly scan your computers registry to look for & remove obsolete, useless junk data and fix any registry errors. This helps to reduce the size of the registry, sometimes substantially to make the computer clean and compact all the time. This, subsequently, reduces registry lookup times and greatly improves your computer performance.
Just bear in mind that, a computer that shuts down for no reason is a sign to tell you either a software or hardware problem. If cannot be repaired timely, they may seriously bring in unexpected damages to the PC or total computer crashes.
