Hello, i just builded my first pc, i followed all instructions but when i finnished and turned on it started beeping, first i get 1 beep, then after like 20 sec 1 long and 3short beeps. And monitor doesnt even turn on. What should i do? I tryed restarting power, taking battary out for 5-10 mins, reinstalling rams and even rebuilding all parts again. (I dont have gpu(or i think its called pci)) And all parts r moveing or rgb and it looks like everything should work.
