Eximo :
What's the problem you are having? I'm sure many people here can help you here and ASUS has reps that sometimes answer questions here as well.
I have an ASUS M5A99FX r2.0 with FX6350 CPU 16g AMD 1600 ram and 750w PSU. GPU is Gigabyte windforce gtx770 4g. While playing recent release games the PC will stop working. The fans are still running and the USB is still powered on. The red CPU led on the MB turns on. Sometimes the system will re-post but other times I have to hard power down and reboot.
