I finished installing a new water cooling system today, and everything went well on my test bench. When i brought the computer to my desk and hooked it up, it booted as normal for a few minutes, and then shut off. I determined that the cpu was getting too hot, and would shut off. While trying to troubleshoot it, one time the PC would not turn on. When pressing the power button, the LEDS and fans spin/flash for about half a second, then go dark. Through various troubleshooting, ive determined that the machine will only boot if the 8 pin connecter to the motherboard is unplugged.
Through spare parts, i have ruled out my RAM and video cards
Im assuming its either my MOBO or CPU.. is there any way to tell specifically?
Help would be great, Thanks.
