Hello Raven_55, it is very important to know which processor are you using and the model number of the memory.
Also, please let me know if this is a new system you are building?
These are some recommendations for this issue:
- Test the system out of the chassis, minimal configuration please. (Motherboard, processor, power supply, 1 memory stick)
- Remove the CMOS battery and leave the system without it for about an hour. Then put it back on and restart the system. Desktop Boards — Troubleshooting BIOS issues
