Task Manager not responding and uknown application launch

Hello guys,
I got my new computer with extreme gaming performance. It comes with Windows 8. I usually leave it on Sleep Mode when not in use so it will be easy for me to go back when I need to. However, I've got an error that says:
"C:Program FilesTabletPenPen_Tablet.exe"
With follow up message stating:
"The extended attributes are inconsistent".
I clicked on the OK button and the Launch Application dialog box appears. I launched the Task Manager to avoid the process and it stops responding. It fails and make a duplicate then removes the other one and so on. And now, I was unable to access the Task Manager to know what the issue is. The mouse cursor seems to be loading which just shows my CPU usage of 100%. I can access the games on my computer and the Internet. Can someone please provide some resolution?
Thanks in advance.
