I have a new SSD (Kingston Hyper 120GB), with a fresh installation of Windows 7 (and several HDDs). For no apparent reason, my computer freezes. I cannot move the mouse, the sound glitches, but after about 10 seconds everything returns to normal. Any suggestions?


I believe that SSD uses a SandForce controller, which has known problems. If you search for "SandForce Freezing" you will get lots of hits.

I believe there are some Registry settings that may at least mitigate the problem.

Here are some threads for reference:





You should also see if there is a firmware update available, but I suggest researching that before you flash, as there have been cases when that caused worse problems.

There may be hope for this issue however. See:

  • @Tom thanks; no personal experience, but I have heard enough complaints about this to stay away from SandForce based SSDs for now, no matter how attractive their benchmarks are. (Also, those benchmarks can be artificially high, since SandForce uses data compression: if your data can be compressed, you benefit, if not, you don't.) – Mr.Wizard Oct 19 '11 at 23:40
  • The failure rate is also significantly higher. – Shinrai Oct 20 '11 at 19:48
  • I didn't see any actual solutions in those posts. – northben Jun 11 '13 at 4:32
