About a month ago my system blue screened on me, I know that this is seen as incontrovertible proof that the hard drive with windows installed on it is either corrupted or windows itself is corrupted(the more likely answer seeing as I am using a new ssd). My computer continued to run fine until last night my computer ,while being used, failed to see my storage hard drive. I restarted the computer and it refused to post from the bios. I turned off the power supply and waited 5 seconds then turned back on the computer and it worked fine, until this morning when it just rebooted it self twice while it was being used. I just checked and my ssd is determined to be fragmented by 16 % percent according to windows. I have heard that it isn't good to defragment a ssd and that I will probably have to re install windows but I wanted more help before I do anything drastic. Any help would be vastly appreciated.
