Gaming computer freezing

[liamcos]

Hi, my computer has been freezing at random times when I play games such as Garry's Mod, PlantSide 2, and mostly Arma 2 OA (Dayz). When it freezes, the frame stops and my audio stops. To fix my problem I thought was to get a new power supply (1000w), didn't work, I got new RAM (16 GB), didn't work, I did a memory test, didn't work. Now my only guess left is to get a new motherboard and/or CPU, but I need to make sure it's the right solution before buying it. Please help!!!

Here are my "specs" to my computer...

Processor: AMD Phenom(tm) II X4 955 Processor 3.20 GHz
RAM: 16.0 GB (RipJaws X Series DDR3)
System type: 64 bit
Motherboard: ASUS AM3+ AMD 880G DDR3 2000 SATA 6Gbps and USB 3.0 Supported ATX Motherboard M5A88-V EVO
