SSD causing BSOD and disappearing from Bios + HDD extremelly slow Boot

[EduardoBZ]

Hello.
I had built my PC on february 2015, its an Asus H81M-C + I5 4400 + GTX 970 + HDD WD 500 GB + 8 GB DDR3 Kingston 1333mhz + AKASA Venompower 550 watts.

Then in January 2017 i got a SSD Kingston UV400 240GB, and everything was fine for a year.
But in February 2018 it started to cause BSOD and disappear from Bios.
I had to sent to USA for warranty (im from Brasil) and had to install windows on HDD again while i wait for warranty. But i noticed that boot was REAAAALLLY slow than was before. It was taking about 4 to 5 minutes to start (on Windows Login screen, not in MOBO screen)

Now, after a LOOONG wait, Kingston finally sent me a new SSD UV400 and for my surprise, the problem persisted. The boot is really fast, about 12 sec, Writing and Reading speeds are above 400 mb/s, as it should be, but again im facing the same problem, i got random BSOD and SSD just vanish from BIOS. I have to turn off the PSU to get the SSD recognized again.

Since the SSD is brand new and im having perfomance problems with HDD, i starting to think its a problem on my H81M-C

What you guys think i should do?

I would hazard a guess that the "Venompower 550" although it looks a good unit has served you well for 3 years. I would try a friends PSU if you can or try borrow one what you are describing sounds PSU related.

UPDATE: I disconnected the SSD and booted windows through my old HDD and started to run some tests.

So now i have 3 HDD:
WD 7200 RPM 500 GB with Windows 10 on it
WD 7200 RPM 1000 GB with Games and Stuff
Samsung 5400 RPM 500 GB, have some badblocks but is stable, i use to store temporary files, downloads, movies...

Then i tried to Defrag them and this happened:

WD 1000 GB was 6% fragmented, defraged fine, 0% after
Samsung 500 GB was 7% fragmented, defraged fine, 3% after (because of bad blocks i think, 86 sectors to be precise)
WD 500 GB (With Windows running on it) was 8% fragmented, and in the middle of the process just crashed (BSOD)
Restarted the computer, tried again, crashed again. Tried one last time, crashed again. (so, 3 times, 3 crashes)

So definitelly its not a SSD problem.
Maybe i will try another PSU, since im not very fond of this AKASA, it produces some weird noises from time to time (buzzing sound)

But, theres any chance of this problem be comming from the MoBo?

well yeah I would not rule it out but that is what I would think you could take it to a PC repair shop they would tell you for sure and it probably would not cost that much,
