Pro, notebook lag no?

Just went to the repair point today to retrieve the notebook, Asus has said that the lag is not resolved and not recognized as a quality issue.

First of all, notebook configuration: ASUS K450jf,intel Core i7 4700HQ four cores/eight threads , DDR3 4G 1600MHz, NVIDIA GeForce GT 745M 2G video memory, 1TB HDD, this configuration also cards.

Here, the notebook is always puzzling and random occurrence of the lag, the hard drive is not bad. Then you may have the same situation as me. The specific manifestation of my question here is:

1. Unable to boot, wake up after waking, easy blue screen

2. Always suddenly lag, change the solid-state drive after more easily encountered.

3. File system suddenly disappears

I am in the repair point processing route: Hard drive Bad track check (no bad road)-Change the mechanical hard drive-change motherboard-Change the SSD (Samsung 850 Pro)-Change the memory, all methods can not be solved, from the replacement situation, suspect this entire K450JF series, even use X450JF motherboard notebook has this problem.

Determine if you are having the same problem as me depending on the operating system log:

Win8 and win8.1 logs ("My Computer" right-admin-Event Viewer-windows logs-system-right Toolbar "filter Current Log" event level select "Warning") performance as: "ID 153 event "(in the warning), that is," on disk 0, logical address 0x ... Retry io operation ", the logical address has been changed.

Linux logs ("Dmesg|grep ATA" can be run at the terminal):
