Hi looking for some help. I changed out my Hdd for a SDD as it was intermittantly failing to read. I Have a MSI GE72 2QD Apache.
Installed a Evo 850 1tb using samsung wizard and the work around for it to read with windows 10, Worked fiine for about 3 days now doesnt show up in disk managment or wizard.
If i remove the SSD and put back in it reads then disapears after about 2-3 hours.
Any suggetions on trouble shooting this problem or how to diagnose the slot.
Computer says its working fine, Any help will be kindly regarded thanks in advance.
