SSD related Crash, BOOTMGR MISSING message, BIOS alterations, fun'-)
I spotted some old threads regarding issues I've been experiencing for many months now, seemingly following an upgrade to a newer SSD. I posted on the thread but was advised to restart anew. So, here goes:
Symptoms: Very random Crashes, Freezes, Blue screens, Restarts, etc. Sometimes hours apart, sometimes days, with BOOTMGR missing press CTRL+ALT+DEL message upon reboot. Pressing [ctrl][alt][del] reboots & only returns to same message.
Side-affects: Some times rearranged boot device order, SSD drive missing in BIOS (it reappears only after off/on of PSU power switch), occasionally the CPU Clock speed &/or RAM Voltage are changed. System clock (ie:Time) & other parameters seem unaltered.
Diagnostics: I've tried many overclock, under clock & stock speed combinations of CPU & GPU & RAM timings as well as some Under & Over Voltages (also with No GPU, just onboard Graphics); new coolers on Drives & CPU, new PSU, rearranging PSU wiring & rails, different power strips & wall outlets; reseating RAM in different slots with all possible configurations, completely, completely rebuilding the system (which is something I do pretty regularly anyway) with SSD HDDs plugged into different SATA ports & repositioned in case(s), changed case, all with same erroneous results. CMOS battery OK.
Failed Remedies: Uninstalled all Overclocking software I thought may be conflicting with each other or making the system unstable or randomly changing the timings, clock-speeds &/or Voltages, etc. Installed SSD Tweaker (very handy software btw) to adjust TRIM & more. I have noticed that the temperature reading on the SSD says Overheated always, even right @ startup after being off for days. I've seen it said that it's not uncommon to have such faulty temp. readings on SSD's & that this really has no performance affects.
Before I commit to a total Nuke & Pave I was just looking to see if any of you found out more about these strange phenomena or if resolution(s) discovered. Any insight greatly appreciated.

...also several various USB I/O Peripherals that I've determined to be inconsequential & dual monitors (though I can't see how it would make a difference, they are both ASUS- 27" Landscape1080p & 24" Portrait1080p).
