I have just bought a brand new computer in parts. I assembled it and tried it, but it is not booting.
- Intel Core i5-4590
- 2 x 4GB of Kingston HyperX Genesis RAM
- Gigabyte Z87-DS3H
- Asus nVidia GeForce GTX 770 (disconnected, no effect)
- Corsair CX750
- WD Green 2TB (disconnected, no effect)
- Antec Three Hundred Two
First when we tried to boot the fans and drives turned on for maybe 2 seconds, then everything turned off for a couple of seconds, and then the cycle restarted.
We tried using the motherboard's CMOS reset switch; when the switch is disconnected everything seems to turn on, but nothing actually happens (same fans & drives on effect). But now, the power switch just turns everything on for half a second and then off again.
The case does not have a speaker, so I am not able to hear any beep codes.
What should I try to fix this?
