My system is as follows:

  • CPU: Intel i5
  • GPU: NVidia GeForce GTX 670
  • SSD: OCZ Vertex 4

From time to time, usually after prolonged use, my computer starts freezing. It does not crash, nor freeze completely, but behaves weirdly in a very specific pattern:

  1. For a second, everything is frozen.

    • if sound is playing, it will give digital artifacts, repeating the last slice (phonetic: trrrrrrrrrrrrrrrrr).
    • screen will not change, mouse movements are not shown
  2. The next second, everything works fine.

This pattern repeats itself until I reboot.

It is not dependent on an application, if I manage to close everything despite the freezes, the pattern will continue even on the windows desktop.

Any ideas as to what might cause this?

This sounds like a firmware problem with the SSD device. Have you updated the firmware to the device? –  Ramhound Apr 24 '13 at 14:36
    
I will try that. Can you tell me why you think it's related to the SSD? –  Wilbert Apr 24 '13 at 14:44
    
Because of the digital artifacts and repeating sound. –  Ramhound Apr 24 '13 at 15:00
    
SSD firmware is already on the latest version. –  Wilbert Apr 25 '13 at 9:31

I would get the data off of the SSD and backed up onto another disk ASAP. This sounds a lot like a failing drive; the freezes are when it fails to read a sector, and it has to repeatedly retry until it manages to successfully read the data. –  Darth Android May 1 '13 at 1:21
