I was also told I should try to disable the auto-defrag or at least see if my system recognises the ssd and prevents auto-defrag. I am a bit over my head here...

First, I believe that you need to understand Linux filesystems. Maybe this will help;Why Linux Doesn’t Need Defragmenting

If you’re a Linux user, you’ve probably heard that you don’t need to defragment your Linux file systems. You’ll also notice that Linux distributions don’t come with disk-defragmenting utilities. But why is that?
To understand why Linux file systems don’t need defragmenting in normal use – and Windows ones do – you’ll need to understand why fragmentation occurs and how Linux and Windows file systems work differently from each other.

Plus a few links at; Linux File System

Part II <- Understanding Linux superblock
Part III <- An example of Surviving a Linux Filesystem Failures
Part IV <- Understanding filesystem Inodes
Part V <- Understanding filesystem directories
Part VI <- Understanding UNIX/Linux symbolic (soft) and hard links
Part VII <- Why isn’t it possible to create hard links across file system boundaries?

Hope this helps.
Have fun & enjoy Linux!

Just to be clear on this: yes, I thoroughly cleaned the unit before installing the new SSD, the bios does not indicate any over heating, over clocking or other problems.
The start up problem was occurring while the original physical drive was in place. As I said before: the computer is only about 3 years old. I simply replaced the HDD on recommendation from several local sources in hopes that would solve the issue. So far there has been no repeat, apparently I will just have to wait & see.
I can't say for sure the problem is solved, it just hasn't happened so far.
Thanks guys for all your input, if the start up problem does occur I'll let you know.

The bios would only report overheating if the overheating was in a monitored resource: most likely only the CPU. Often overheating of other components is not detected. Boot problems due to startup power issues that do not continue are often undetected. In any case, if your problem is solved by the cleaning and swapping the drive, you may never discover the cause or WHICH of those two things resolved it.

I will be glad if the issue just remains resolved.
