Hello, So this problem started when BF4 was launched, every time I spawn my computer shuts down and restarts. The last few sounds in game start looping for a few seconds. I did everything to try and fix it, change drivers, reduced over clock, reinstalled GPU and RAM, reinstalled OS. Nothing works. Also, the same problem appears when I do "Rate my PC" in the System Control Panel, which is odd. Some forums suggest the PSU may be bad although it's quite new, not even 6months old. Anyways here are my specs: Intel 3770k 4.2 GHZ NVIDIA GTX 570 8 GB RAM BALLISTIX 2TB HDD MSI Z77MA-G45 MOBO CORSAIR GS700 PSU H100I COOLER.
