Well, unless they sent you another faulty CPU, I am really not sure what else can be causing internal timer errors hardware-wise. We can run through hard disk diagnostics:
Chkdsk:
There are various ways to run Chkdsk~
Method 1:
Start > Search bar > Type cmd (right click run as admin to execute Elevated CMD)
Elevated CMD should now be opened, type the following:
chkdsk x: /r
x implies your drive letter, so if your hard drive in question is letter c, it would be:
chkdsk c: /r
Restart system and let chkdsk run.
Method 2:
Open the "Computer" window
Right-click on the drive in question
Select the "Tools" tab
In the Error-checking area, click <Check Now>.
If you'd like to get a log file that contains the chkdsk results, do the following:
Press Windows Key + R and type powershell.exe in the run box
Paste the following command and press enter afterwards:
get-winevent -FilterHashTable @{logname="Application"; id="1001"}| ?{$_.providername –match "wininit"} | fl timecreated, message | out-file Desktop\CHKDSKResults.txt
This will output a .txt file on your Desktop containing the results of the chkdsk.
If chkdsk turns out okay, run Seatools -
SeaTools | Seagate
You can run it via Windows or DOS. Do note that the only difference is simply the environment you're running it in. In Windows, if you are having what you believe to be device driver related issues that may cause conflicts or false positive, it may be a wise decision to choose the most minimal testing environment (DOS).
Run all tests EXCEPT: Fix All, Long Generic, and anything Advanced.
