Ive built a new PC today using the asrock z390 phantom gaming 4s and the PC doenst start and the 3rd and 4th lights are on. The graphics card im using is a GTX 750 TI from my previous PC (waiting for a RTX 2070 Super) and a HDD from my previous PC along with a new M.2 SSD.

Dear Herobrine24,

Thank you for choosing ASRock.

Regarding your case, we provide some suggestions to try:
1.     Clear CMOS to load BIOS default.
Please remove the power cord, and follow the user manual p17 to clear CMOS.

2.     Only install CPU and one stick memory to check if the system can boot into BIOS properly.
3.     Please try to install one stick memory at A1, B1, A2 and B2 slot to check if the system can boot into BIOS properly.
4.     Reinstall CPU and check if CPU socket pin is fine.
5.     If it is possible, please change another CPU or DRAM to check if the system can boot into BIOS properly.

Thank you!
Yours truly,
ASRock TSD

I have tried resetting the bios and that didnt do anything. I dont think i can enter the bios without a graphics card because my CPU (Intel i5-9400F) doesnt have integrated graphics.

I also installed the new graphics card today and its the same results
