Do you think upgrading to Windows 10 can solve it?
or it is better to reinstall windows 7 first?
the technician who replaced for me pc board , hdd and ssd
and cooler examined all the ports and cables most of them are new
so i cannot see how it can cause the problem.

why i still see on event log 381k temperature after replacing the cooler?
Do you think power supplier can cause this problem?
this is the only part i did not replaced

is there any tool to examine the power supply it gives?

It is not smart to upgrade on an unstable system.
Depends on what cooler you have replaced with what other coller and how it is installed.
A PSU can cause many problems, I can't be more specific.
Replacing a component doesn't automatically rule it out just because it is replaced, a replaced/new component could still cause problems.

you can see what cooler i changed if you scroll back
i do not think i would get more help here thank you
obviously the cooler was not the problem
no one knows what is the problem

You give very little information about your system specs, how can we help proper without some actual specs? You only give the manufacturers of the components, but that is not enough. Read my instructions below to fill in your system specs so we can check more.

That is what we're trying to do, diagnose to find the problem. Do you really think that this is a 1,2,3 thing?

Please fill in your system specs

Please follow this tutorial and download the tool. The tool will give you detailed information about your system specs, please fill in your system specs more completely.

When has the CPU been replaced, because of the thermal paste.
Improper replacing the thermal paste could cause high temps too and even damage the CPU

i am not sure i understand the cpu has not been replaced yet
only mother board and after a week the cooler too
also hard disk been replaced before that
do you think the original cpu is damaged?
is there a way to check it?
do you recommend to replace it any way?

Thermal paste

Thermal grease (also called CPU grease, heat paste, heat sink compound, heat sink paste, thermal compound, thermal gel, thermal interface material, thermal paste, or grey goo) is a kind of thermally conductive (but usually electrically insulating) adhesive, which is commonly used as an interface between heat sinks and heat sources (e.g., high-power semiconductor devices). The grease gives a mechanical strength to the bond between the heat sink and heat source, but more importantly, it eliminates air gaps or spaces (which act as thermal insulator) from the interface area.

I don't think the CPU is damaged, honestly don't know.
My thoughts are that replacing the thermal paste might help a bit.
You can test the CPU using Prime95 and IntelBurnTest

Diagnostic Test

CPU TEST

Run Prime95 and IntelBurnTest to stress test your CPU. Prime95 - Stress Test Your CPU - Windows 7 Forums & CPU - Stress Test Using IntelBurnTest

Warning

Your CPU temperatures will rise quickly while under this stress test. Keep a keen eye on them and abort the test if overheating occurs.
