Hey guys, first post here and I was just looking for some advice on what might be going wrong with my system. My PC freezes at seemingly random times; it can be playing a game, watching videos online or even just displaying explorer. The PC stops responding and often I hear a buzzing from my speakers (not the tower), I have to force restart and then it also has problems restarting. I get asked to do either a startup repair (which just does a restore or sometimes crashes itself) or to start up windows normally, which can take anywhere from 1 to 8 or so tries to correctly boot. Sorry for the rant, I'll post my specs below.
Motherboard: MSI 770-C45
CPU: AMD Phenom II X4 810 (with AKASA heatsink) ~25*C
GPU: Sapphire HD 6750 1GB ~32*C
RAM: 2 x Micron 800MHz 2GB DDR3
HDD: Seagate 250GB
DVD-R: Sony Optiarc
PSU: 600W (can't check the brand right now)
OS: Windows 7 64bit
I've tested the RAM with the memory diagnostic built into windows which comes up fine, I can't think what else it would be. thankyou for any help given.
