The thread topic basically explains it all. I started to assemble my computer outside of the case, on top of the motherboard box. When I got the CPU, stock Intel heatsink, 2 sticks of RAM, and the graphics card installed and after plugging in my 24pin, 8pin, and 2 6pins for my motherboard, CPU, and graphics card respectively, I attempted to boot. The CPU, PSU, and GPU fans turned on and then immediately turned off. After a few seconds the system will try again, but with the same result. This continues until I flip the switch on the PSU. Never makes it to POST.
After reseating the CPU and checking to make sure the heatsink was on properly, I was getting the same result. I started googling and found this:
I have tried every step of this with no luck. I did the paperclip trick (plug it into the green and a black pin the 20pin PSU connector) to test my PSU. It worked. It was also used in my older build from 2007 and was working not even 3 hours before the install began to fail.
You mention a 20 pin connector. Doesn't that motherboard require a 24-pin connector?
There are adapters that will convert a 20-pin to a 24-pin rather than just plugging the 20-pin into the MB connector & leaving 4 pins unused.
I still think that you have a power issue, as in not plugging in the 4 (or 8) pin ECPS connector, or the PSU being bad.
I have my PSU 2 4pin CPU connectors plugged in.
My PSU would have had to go bad between the time I removed it from my older system and plugged it into the new one. haha. It is nearly 5 years old though... I can try plugging it back into the older computer when I get home just to see if anything happens.
Suppose I'd rather have a bad PSU than a bad CPU/Motherboard....
I'd go with Motherboard... if you get no beeps when memory isn't installed then your motherboard is probably the culprit. You will know soon enough when you put your PSU back into your old PC though.... Good luck.
Just curious, if I were to remove the CPU and try booting, what would happen?
I ask this because I am wondering if there is a good way to tell if the problem is my motherboard or my CPU. Looking online at others who have had my problem and the consensus is that it's either the motherboard or CPU.
It won't hurt anything... but I doubt it will even attempt to turn on... it also won't verify your issue... it still won't boot without the CPU... so doing that gets you nowhere.... Motherboards fail FAR more often than CPU's. CPU's rarely fail(unless you're overclocking at fry it - even then it is difficult to kill a CPU)....
EDIT - Please verify your CPU pins are not bent at all... they will be on the motherboard.. they should look uniform.
I'm in the "no beep" and "no debug" category, it's looking like I may have a faulty CPU.
I am probably going to head to Microcenter this weekend and exchange the i5 for another. Maybe they can pop it in a motherboard to see if it actually is faulty. Probably just take both CPU and motherboard, just in case.
