So I just came back from a 2 week vacation and when I used my PC everything was working fine, but while playing a game the PC froze and I had to turn it off using the button on the chassis. After using the PC again for like another 2 hours or so the PC froze again but this time my monitor just went black and said it was going into sleep mode but the PC was still on. After turning off the PC using the button on the chassis again it wouldn't find my SSD or HDD to boot off ( OS is on SSD). I unplugged the SATA cable from both the mobo and the SSD/HDD and it still wasn't able to find a device to boot off. I then replugged the SATA power cables form the PSU and after turning it on the PC would just turn on for 1 second and then turn off (keeps repeating). I took all the components out of the chassis and booted it outside of it and the problem still persisted I also reset the CMOS and even bought a new battery but still nothing. I also took out the RAM and left one stick in and still nothing. Im not sure if its the PSU or mobo but I'm starting to think its the mobo because of the previous problems. I also can't test if the PSU is dead since I don't have the tools to test it. really confused here :((
All help is appreciated and thank you for your time


Also my PC is only 10 months old

PC specs:
Intel i5 4670k
8GB Corsair Vengeance RAM
GTX 770
Gigabyte GA-Z87-HD3 LGA 1150 Motherboard
Corsair CS750M 80+ Gold Modular Power Supply
