I just finished my first PC build, which I've had issues building, with the old motherboard. I now got the new motherboard and re-built the PC again. Everything was working fine, I managed to install Windows, and was installing some software and monitoring the temperatures when suddenly the PC started rebooting and then shut down. I tried to reboot it obviously but the monitor wasn't receiving signal from neither my GPU or Motherboard. I had some Graphics Drivers downloading in the background on it's own by Geforce Experience, so I guess it could have been that it tried to apply the new Drivers but shut down during boot? Though why doesn't it work with the DVI-D cable attached to the motherboard? Anyways, here's my specs: Gigabyte GTX 760 2GB Asrock A88M-G/3.1 AMD Athlon 860K (With stock cooler) Corsair CX500 Versa H21 Ballistix Sport 2x4GB Looking for some quick suggestions of what the issue could be and what I can do to fix it. I've tried removing CMOS battery and booting with just 1 RAM stick.
