My MSI motherboard is not functioning properly. It will run just fine for a while only to "crash". It will randomly turn off my monitor, mouse, keyboard and sound (or anything via USB port). In addition, in order to get anything back up, I have to pull the plug seeing as my power button in front of my tower does not work when this happens. I didnt OC anything. All drivers are up to date.
Here is my build
MSI 890FXA-GD65 AM3 AMD 890FX SATA 6Gb/s USB 3.0 ATX AMD Motherboard
CORSAIR XMS3 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory
Microsoft Windows 7 Home Premium 64-bit 1-Pack for System Builders - OEM
PowerColor AX6850 1GBD5-DH Radeon HD 6850 1GB 256-bit GDDR5 PCI Express 2.0 x16 HDCP Ready CrossFireX Support Video Card
AMD Phenom II X4 965 Black Edition Deneb 3.4GHz Socket AM3 125W Quad-Core Processor
RAIDMAX HYBRID 2 RX-730SS 730W ATX12V V2.2/ EPS12V SLI Ready CrossFire Ready Modular Modular LED Power Supply
Assuming all drivers are up to date... I would first download and run memtest and let it run through several passes. Very well could be bad memory... After that, stress test with Prime95 to check if you are stable at full load for an extended period of time.
