Hello WakeboardH205,
Welcome to PCHF.
First thing, wheather you removed the
CPU or not, double check that this is seated properly (even if it means reseating), and the heatsink and fan is working properly.
The reason why I am leaning more towards
CPU than any other component, is that if any other component was not corrected properly, you would receive warning beeps. Also, the PC would only freeze when going into BIOS if there was a
CPU or motherboard problem. Make sure the 4 pin molex power connected is properly connected.
