So today, I turned on my PC, but it did not boot. It went to the bios, and then "No Signal" appeared on my monitor and the PC then shut off. It would continue this loop until I either entered the bios, or unplug the power supply. I opened up the PC and saw that all the fans were running. Please help!
Parts:
FX 6300
CM Hyper 212 Evo
Radeon R7 240
2x Crucial Ballistix Sport 4GB RAM
Rosewill 450W PSU
 
Solution
Try unplugging the 24pin motherboard power cable and the 8pin cpu power cable then plugging them back in again and see if your PC boots and will POST.
