I'm not quite sure where to post this as I'm not entirely sure what's causing the problem.
I'm running Win 7 Ultimate 64 bit on a Kingston Hyper X 120G SSD, w an i7 4790, a Gigabyte GA H97 D3H mobo (rev 3), a GTX 650Ti Boost SC, 24 GB RAM (2x8) and (2x4), and have a SeaSonic S12II 620W Bronze PSU.
This just started happening today. I was playing a game (Call Of Duty MW2) and suddenly my computer froze up accompanied by what I'd describe as a fairly loud buzzing noise, that to me sounded like some kind of rapidfire oscillating electric noise. I was wearing headphones so it sounded quite loud. The computer just hung there.
I tried Ctr + Alt + Delete to bring up Task Mgr and it wouldn't respond, so I pressed my computer's reset button. It rebooted normally. I loaded HWMonitor to see if anything was out of the ordinary. The one strange thing that I could see were the voltages, which made me suspect the PSU. The peak voltage on the 12V rail showed 32W - I'm thinking if it had actually spiked that high it would've fried my system. I rebooted to see what it would show the second time. This time it showed a peak of 81W !!! In the current voltage column (vlaue) it showed the voltages fluctuating from about 11 to as high as 18, mostly hanging around 11 to 13.
Here is just a momentary screenshot of it showing 15W:
But like I say it averages probably 11 to 13
I reloaded Call of Duty with HWMonitor open, and saw the Voltage jump up to 24W
It didn't freeze but I just closed out the game.
The only thing I've done to my machine recently was to add 16 GB RAM (2x8) to my system which also had 8GB (2x4), bringing it to 24GB in dual channel. I did this five days ago, but have been editing and gaming without problem for five days
I had asked advice on the RAM upgrade here, and got responses form Fingers and riider in this thread to help me.
I'm not sure if I'm on the right track with this, or what could cause the freeze and noise but I'm concerned now about doing damage.
