I disconnected the 2nd drive and I put the cable on the new ssd that I will use to clone the main drive so that the ssd will become my main drive. I was defragging my main drive when I decided to pull the CD ROM drive cable and put the cable in the 2nd drive that I disconnected earlier but when I connected the 2nd drive my computer froze and I manually restarted it on the power switch and after that only the CPU turns on but the monitor doesn't have display just standby and my mouse and keyboard has no light nad dram_led is solid red.

What could be the problem? Is it the motherboard or the power supply?
