So Occasionally when I turn on my pc, I get the message "a disk read error occurred press ctrl + alt+ del to restart" and doing as instructed starts and endless loop of frustration. The only way I seem to be able to fix this is by taking off the side of the case and fiddling with the cables to my ssd OR if I give the pc a sharp bump it works. This has started to happen more and more often, at first it was once or twice a week but now it is happening daily, in addition to this, it has started having strange crashes, by strange I mean my skype closes and funnily enough it has a disk i/o error and that is shortly followed by a freeze and a blue screen. I am assuming that this is a loose cable but I have checked the cables and they all look fine. The ssd is less than a year old and the software that came with is says the health status is good. In case it helps the ssd I am using is a Samsung ssd 840 EVO 250 GB.
Since this error in computer becomes more and more frequent, there are many third party tools available for this typical problem.
