Hi, Help me please. Within this month I have already encountered 3 blue screens all memory dump. What can cause this and how do I prevent this. My system is brandnew and that what makes me nervous. Here's my setup. Windows 7 Ultimate 64 bit Core i5 4590 Gtx 750 Ti (with power cord) 4 GB DDR3 PC 1600 2 x 500 HDD Seagate PSU 550w Motherboard Gigabyte socket 1150 (ofcourse) chipset H87 Is this related to my psu unable to handle the system power needed? Also in the long run what can happen to my PC if I didn't solve this? oh yeah just want to mention that I'm just using a windows 7 activator. Thanks.
