I'm using a motherboard (MSI-7592 G41) and I was using 4 hard disk through it in the past. Two of them started to show problem so, I stop using them for a while. I thought it was the problem of the hard disk. But I checked it on another PC, there were INDEED some problems in them which I fixed with chkdsk command.

Upon further checking out I found it was the cable from the power supply (dont know the name but i have the picture of it below) at fault. So, I replaced them.


Now when I plugg all 4 hard disk on my pc. It is working fine and showing all hard disks but I feel like there is something lagging in my system. SOMETIME it hangs... but most of the time it works fine....

So, my main question is... should i continue using 4 hard disk on my motherboard... will it be ok or not...
Hardware specs of all hardware would be helpful to AVOID guessing what it could be.

Power Supply Make/Model Wattage?
Motherboard ( missing some designator info such as P23 or P26 etc to the part number of MSI-7592 G41)?
RAM?
CPU?
Hard Drive Info
Video CARD(s) info?
Operating System Version?Thanks for the reply
