MX100 512GB random freezes || Win 7 SP1 || Acer Aspire 5742G



I've recently purchased a brand new 512GB MX100 SSD to replace my older HDD. After cloning my Win 7 on the SSD, I put the HDD in an optical drive caddy and plugged it in the optical bay. The laptop is an Acer Aspire 5742G.

Windows 7 boots smoothly, The issue comes that the whole computer freezes at random points, from 1 minute to several hours after boot. I've tried to relate the freeze with Intel RST service action or disk full access speed, but I could not find out any precise cause yet.


I did see this issue was adressed on the forum back in august, and tried all I could do among the suggested solution, ie removing acronis cloner, updating AHCI controller (currently Intel 5 Series 4 Port SATA AHCI Controller with Intel RST, even updating BIOS to latest genuine version (InsydeH2O 1.30), and using no swap file. Nothing has solved the issue yet. The one thing suggested I could not try is enabling hot swap in BIOS, as this option doesn't exist in InsydeH2O.


Has the issue finally been adressed since it first appeared (could find the link below, but wasn't on Acer machines) ?


Thanks for any help !
