Pc shuts down suddenly

This problem started a week ago.

When the pc shut down i can`t turn it on right away (nothing happens), so i have to unplug the power cord for about 10 secs to turn it back

i thought the problem was processor overheated, so i bought termal paste, now temps are good, arround 39C IDLE and 55 under heavy load.

so, i don`t know why my pc keep shutting down suddenly.

(i have pc specs in my sing, if you do need any other info just let me know)

i really appreciate your help, i`ll be waiting your answer, thank you.

I experienced something similar a few years back on an older rig, it turned out to be the PSU was dying might well be the same thing on your system.


Steve

any way to know if its the psu? some software test?

because i don`t have any other psu to check.

Btw i bought this psu only one year ago

Sorry I have no idea about testing software

Problem Solved.

I realized that CMOS battery was causing the problem; the battery was low.
so i changed it.

no more suddenly shut downs, pc its working just fine.

Thanks for help anyway.

Solved only For 3 days,

pc just shut down today twice.

its was not a CMOS Battery problem.

heres its the minidump files.

Thanks.

First crash was probably caused by tcpip.sys and the second your video driver.

i would

dl a fresh video driver and install it
reinstall you network driver
run a system file check
type cmd in search>right click and run as admin>sfc /scanno
Update the drivers listed below

Thank you.
