Without any more information to go on, all I can tell you is to unplug the SSD, throw it in the freezer, let it set for awhile, and hope for the best. Good luck!
(Im just kidding don't actually do that)
Okay, that is a little vague, can you list your system specs and tell us the brand & model of the SSD and how you have it attached and what is its function in your build (e.g. boot drive, cashing...).
