Hello!
Please, anyone could give me some info about below?
First of all, i would like to be clear, i read a LOT of posts with similar problems and no convinceble solution. ( HELLO ACER)
I have a Predator Helios 300 (PH315-52). I have a factory default SSD Samsung NVMe 256GB and it works Perfect. I bought recently a Kngspec 1TB NVME and i am facing some issues.
First i used as a OS main storage, as C:. I could use for a time, perfectly, tested with Cristal Disk Mark and all tools you can imagine, but it sudenlly stops, give me a BSOD and after boot, returns to me a "No Bootable Device". I did all test i can, so i decided to use it as a simple storage "D:" and return the system to Samsung. It worked very well for some weeks but now my Kingspec suddenly stops and disapear from Windows explorer and all other places. If i restart windows, it cannot back on, but only if i shutdown and power on again.
I have no performance issues, i have no freezing during games or videos, and it seems to stop working during idle time.
What i did:
- Format
-Using AHCI on bios ( not optane )
- Run tests
-All terminal diagnosis and all this kind of stuff
What i read about:
- A possible incompatibility of PCIex versions, or speed, i guess. But i am not shure how to diagnosis this.
Consideration (for ACER, if Possible):
-Its bios is under 1.12 version and there is no further versions.
-The bios seems to be a 90's computer bios, a really piece of junk (no ofense)
-The bios do not have any mention about PCIex speed or compatibility, so i can't do any tryies.
-The options on BIOS are very poor.
So, if have some one could give some help or acer's staff give some attention, please, do it! I don't know how to solve this anymore.
In advance, i would like to say thank you.
