[SOLVED] SSD and HDD are not detected in bios or disk manager

[derscharfschutze69]

I have a segotep warship evo II, a case that has 2 buttons for fan speed control. Recently I went to the local repair shop to get a new PSU installed. Everything was good, I got home and started playing some games. I was amazed at how quiet my new psu was and I wanted to put fans to low speed to see how quiet they would be. PC was idle at the time..
As soon as a put a fan control lever to low, my pc crashed. My boot drive,SSD, is gone and no longer detected.
I tried reinstalling windows and it worked but my ssd was gone from both bios and windows disk manager. I tried backtracking to what has caused the issue in the first place and I tried lowering the case fans again. Bam another shutdown,now my hdd is not showing up either. I have only my m2 ssd left... are they fried ?

What's the model name of your new PSU?

If it's some low quality model, then it may have fried your drives.

Corsair CX750M... Why would case fan controls, fans that are not connected to the MB fry my storage drives... what the fluff is going on... I would record what I mean but I am afraid of losing my last storage drive.

Fan control switch could be improperly connected and may have forced PSU to output abnormal voltages and kill your drives.

Oh that better not be the case because by God I am going to ruin their winter holidays hard..
I did notice that they changed the fans from top to front, I have 5 and they put the RGB ones up front for some reason.
