PC wont power up - 4 pin ATX 12V cable when connected stops fans
Last response: in Components
Hello,
After 15 months use my PC wont pwer up. I checked the power supply by shorting the green/black pins and the fan turns on. I connected the PS back to the MOBO (using 24 pin connection) and the CPU fan also turns on. As soon as i connect the 4 pin 12V supply cable none of the fans work. I have all the Hard drives, disk drive disconnected btw. Any ideas why the power is lost when the 12V/4pin connector is added?

Without the 4 pin 12V connector the CPU has no power so BIOS cannot make it past very basic functionality like sending power to fans. Post your full system specs then go through the boot checklist, it should help solve the issue.
