so this is the first pc ive built. i just assembled everything, and when i did my first boot i noticed this was happening. the motherboard seems to turn on and off several times before finally turning on after about 7 seconds. theres no video signal going to the monitor from my gpu or integrated graphics. i thought maybe it was the psu so i tried with a different one and the result was the same. i moved the ram to a different slot and even reset the CMOS but nothing so far has done anything. is one of my components faulty? i just want to be able to use my new pc :(
