Why your pc turn off without reason
The computer may be shutting down for the following reasons, you need to
verify these
1. If the Ram size is too less, there is no enough memory to run other
process, this will cause the operating system to restart when it can't
execute some of its core programs. Try increasing the RAM size.
or increase the virtual memory space.
2. Maybe the power supply of your computer, maybe the power switch is not
well attached to the motherboard, check all the cables on your PC.
3. If there is a virus, malware's or trojans, these can be eating up your
entire CPU memory, please scan for a virus and use an antipsyware. check
if any process is eating up the CPU memory. Go to task manger and Process
, this will list all the process running in Your PC.
4. Maybe it's CPU temperature that is the problem, because if your
computer gets too hot it will shut down. Check the temperatures with a
program called SpeedFan (

5."It may have been because of a power "hiccup". It's not exactly a power
surge, or a dip, but it's enough to disrupt the computer itself. Result?
Your system reboots in no time flat - or goes into an error screen
(commonly referred to as "the blue screen of death"). When this happens,
there's still a chance that your computer will be able to recover the
file you were working on, but it will most probably be fragmented or in
fragments. If you already have a surge protector and a UPS, then check
the power cord itself for looseness or breaks."
