Speccy has a tendency to occasionally throw temperatures out there which don't jive with the other temperatures being reported. For this reason I'm less than inclined to take the temperature or 78C at face value. I would suggest looking in the BIOS to see what is reported there, these readings are the most accurate you are going to find short of using expensive test gear. If the CPU temperature is mirrored in the BIOS I would pay special attention to cleaning the heatsink and fan assembly on the CPU. If this does not resolve this then you may need to replace the thermal compound between the CPU and the heatsink.
I am a little concerned about some of the HDD's S.M.A.R.T. attributes. Specifically the Reallocation Event Count and the Current Pending Sector Count. I would suggest running chkdsk /r.
Please run chkdsk /r if this is a HHD, or chkdsk /f if you are using a SSD.
To run chkdsk /r or /f you will need to open the Elevated Command Prompt.
To open the Command Prompt as an Administrator please do the following.
Click/tap on the Taskbar Search icon (magnifing glass) and type cdm.
You will see Command Prompt under Best match, right click on Command Prompt and select Run as administrator.
Copy and paste the appropriate command below in the Command Prompt, then press Enter.
If this is a hdd use chkdsk /r.
If this is a ssd use chkdsk /f.
This will automatically start the chkdsk /f scan.
As the scan runs you will see a running percentage of the scan at the bottom of the scan.
There should be a short message when the scan ends, please post this message in your topic.
This will take a while to run, please be patient and allow it to complete the scan. Do not stop this scan as this can damage your operating system.
Edited to add:
