Imac Possible hard drive issue?

I have a 2011 Imac with 16GB Ram and a 1TB Sandisk SSD. I was having issues doing local backups, so I command + R and got into the Disk utility and verified and repaired the main drive. nothing I haven't done plenty of times, right? Now once I did that, I clicked on the Macintosh HD partition, and went to verify it, but it said it could not verify disk and said it needed to repair, then but then it could not repair the disk. Tried to reboot the computer but it then would not boot up properly. It just loads maybe about halfway, then totally shuts down.

Im not sure if this is a probably with the HD itself or something I did(or maybe a weird coincidence?), as I have repaired and verified the disk plenty of times, and the computer was working fine before I went into the disk utility. Not sure whats wrong but id like to weigh all my options before I have to resort to going to a local backup.

iMac, OS X Yosemite (10.10.3)

If you have had to repair the drive a number of times this may indicate the drive is failing. You can run Apple's Hardware Test (Using Apple Hardware Test - Apple Support), if you do run it a minimum of 2-3 times back to back in extended mode. The reason to run it multiple times is it does not always pick up errors however when it does they are correct.

However for more reliable testing, take the machine to an Apple Store or AASP to be professionally diagnosed, they will have the proper tools for doing so.

Please let us know what it turns out to be.

just to clarify, Ive verified disk before a bunch of times, but ive never actually had to repair the disk or found anything wrong with it until now. Its just very weird that I do one almost routine thing and then this happens when it was working fine before I went into the disk utility.

I see, perhaps I misunderstood your initial post.

However it still is not a bad idea to run AHT multiple times back to back. One thought.... before taking the time to run AHT multiple times (this can take hours) I would recommend posting an EtreCheck report of your computer and we can look for obvious issues.

Can I run that software from a thumb drive possibly? currently the mac wont even boot up. It gets about halfway and then shuts down, unless im in the emergency partition.

No, it's an app that resides on the computer. If the machine will not boot up, I think it's time to take it in for service and have it professionally diagnosed.
