i have almost same problem like you. my gtx 1060 no display after few minutes playing games. tested with gtx 1050ti,no problem. RMA the 1060, got new one,problem still happen. so,decided to change the psu,its fine. using evga 600b before change to 700b ( same price given by shop  )

so, that my 600b psu is a bit faulty. it cant support gtx 1060 while in game.

Anyone can recommend a suitable place for me to do this upgrade in Penang, mainland area? i would like it to be done within a day.

Sure the SSD is faster than the HDD due to no moving parts, but since I have no plan to change PC or replace the boot drive once-per-3-years, a SSD with longer endurance rate is needed.

SSDs from PNY, GALAX and Western Digital are definitely a no-no this time around. I know it's kinda blowing my target budget, but it seems that both possible drives are priced over RM 400:
-SAMSUNG 850 EVO 250GB (TLC V-NAND) (RM 487)
-SAMSUNG 850 PRO 128GB (MLC V-NAND) (RM 422)

Very difficult to choose between the two, I guess. 

Where i can get all those ?
