When I upgraded to Win10 from 7 I discovered that my SSD was no longer running in AHCI mode - it had before. So I went through getting it back on AHCI and it seems to be working fine. However since that time I've had frequent BSOD's coming out of screen savers etc. I've checked my drivers using Driver Booster 3 and updated all that were old with no change. I'm not sure if this is coincidental or if something else is crashing the system. It's a Samsung 840 EVO. Let me know what else you may need.
