Why sometimes my computer automaticaly restarts, and while turning on, i get that i need to reboot it and change proper boot? I had my pc fixed one mounth ago. Also it wont get "rebooted" until I open pc, and a little move all iner parts in it?
If they are not prompted (in the case of automatic updates) then your computer has encountered an unrecoverable kernel level error and so has had to restart to get back into a known state. These are bad, very bad and should not be ignored. In fact these are the dreaded Blue Screen of Death warnings and will even show you the infamous blue screen on older operating systems or if you disable automatic reboot (useful to see the cause).
Possible causes include.
Faulty hardware. The kernel can only work if the hardware it is running on works. Even if 1/1,000,000,000,000 operations errors then your system will struggle to even boot. Sadly hardware does not last forever and will need replacing eventually due to various physical problems related to age (such as electron migration).
A buggy driver. Drivers are part of your kernel yet developed by people other than the OS manufacturer. As a result they are subject to different and often rather poor quality control. If they error on system older than windows Vista then the OS is forced to reboot with a BSoD.
Damage to the OS kernel via some means. Can either be malicious malware trying to install worms or HDD data corruption (very rare). Obviously if the files are damaged they will not work well and will error.
If this is a BSoD error, there will be a reason why the system restarted. It will give you what module failed and an error code why it failed. Posting these may allow us to help further.
What happens if I dont full my batery entire 12 hourse, i hyst got new pc
I can only assume you have a portable PC with a inbuilt battery for mobility. Modern computers should automatically shut down long before the batter reaches critical levels of depletion for safety and to prevent damage to the battery. Since it is likely powered by lithium ion batteries they need this safety as they will literally explode if not treated carefully and users are too irresponsible to manage them safely themselves.
If you do not charge the battery within 12 hours of depletion (well reaching a low level) then you run the risk of permanently damaging the battery. It will not explode (is safe) but certainly may cause it to lose maximum charge capacity over time. As a rule, if the OS warns you of low batteries you should consider stopping or plugging it in.
