So this has been happening for a while now, but recently it has been more frequent, not sure why.
Sometimes when I am playing games (Guild Wars 2 is the most recent example I've got) or watching videos (MKV 720p x264 on VLC Player) the computer sometimes freezes for a few seconds and makes this angry buzzing noise from the speakers, I suspect the noise is just a side effect of the freezing though..
- Asus P7Z77-M
- Intel Core i5-2500
- 650W PSU
- 8GB RAM
- NVIDIA GTX 560 Ti
- 2TB HDD - Operating System (Win7 Pro)
- 1TB HDD - Data
- 500GB HDD - Data
I haven't been able to narrow down what is causing this problem. I currently have the bios setup to this "smart overclocking" which basically bumps it up on demand, I think.. I have a temperature monitor always running so I know it's not overheating..
I can't recall correctly, but I think that when the lock up occurs, there is a spike on the CPU usage, which might be caused by the system (I found this using Process Explorer).
All drivers are up to date.
I Forgot to mention that I'm also using a 64GB SSD in a RAID 0, to work as a cache drive for the 2TB drive (Intel Rapid Storage Technology)
EDIT 2 Also, another problem that I have encountered is that the computer completely freezes, at any given time, seemingly randomly. I have my computer on basically 24/7, and I've seen it freeze a few times completely without return, where the only solution is to reset. When this happens, if there is sound playing, it simply stops. I've noted that it has frozen even when no one is using. I don't think it's sleep-related problem because this has happened even when I am actively using the computer.
