I upgraded last night from Windows 8 to 8.1 and started having a problem.


All goes well during boot and up to and including login.


After that, the desktop shows and the icons appear.  After about 5-10 seconds the icons disappear as well as the icons on the taskbar.


They will reappear after about 20 seconds. This repeats continually.


According to Task Manager, CPU usage is topped out for periods of time.


Any help would be appreciated.

 I'd start an administrative command prompt and issue this command: sfc /scannow .  I'd also scan the system event log for entries flagged ERROR.  To do that download Minitoolbox and run it with the option "List last 10 error events" checked.


 Good luck.

Make regular full system backups or you'll be sorry sooner or later.

Hi Cutsit, welcome to Bleeping Computer.


Were you having any problems with Windows 8 before doing the upgrade?


Please run sfc /scannow
The sfc /scannow command scans all protected system files and replaces corrupted and incorrect versions with correct Microsoft versions.
To run sfc /scannow in Windows 8 you will need to open the Elevated Command Prompt.  The easiest way to do this is to press the Windows key windowskey_zps092d5c75.png and the X key at the same time.   A menu will open with the option Command Prompt (Admin), click/tap on this.
You will see a window similar to the one below.
When the Elevated Command Prompt opens copy and paste in sfc /scannow, then press Enter.
This will take a while,  have patience and allow it finish.  Stopping this scan could damage files.  
When the scan is finished please post the log of this scan.
To find sfc /scannow log, reopen the Elevated Command Prompt using the Windows key windowskey_zps092d5c75.png and the X key method outlined in the instructions above. 
When the Elevated Command Prompt opens copy and paste the following in the Command Prompt, then press Enter.  
findstr /c:"[SR]" %windir%\logs\cbs\cbs.log >"%userprofile%\Desktop\sfcdetails.txt"
This will place a new icon on the desktop titled sfcdetails.  Click/tap on this to open the log, copy and paste it in your topic.

Family and loved ones will always be a priority in my daily life.  You never know when one will leave you.
