A dead cpu

[Bosshogg213]

Is my cpu is dead? every time I try to turn on my pc on it turned on then off immediately so I took it apart and rebuilt it and the same thing is happening I don't know what to do I have the cpu fan plugged in and the cpu 8 pin power plugged in

That doesn't necessarily indicate a dead CPU. A dead motherboard or power supply might also cause this. The only way to know for certain is to swap components out until it works again.

What happened that caused it to not work? What are your system's components?

here are my specs http://pcpartpicker.com/list/Y9xrr7
when i was installing the cpu i put way too much thermal paste on so i cleaned it off and reapplied it and built it and had to do it again when i dismantled it and i also noticed that there were some scratch marks near the motherboards standoff screw holes

Did it ever POST, or have you not gotten it to work at all?

It could be anything. Try setting it up outside of the case with only the basics - motherboard, CPU with stock cooler, PSU, 1 stick of RAM. Try different sticks of RAM in different slots. Use onboard video. Don't connect any peripherals until you get it to post.

It's possible that one of your components came DOA. The CPU itself is the least likely culprit, but I've still seen it happen. Do you have any other known-working parts you can swap in, such as PSU?

Your motherboard has a debug panel on it (the LCD display in the top right) ... watching the codes go past as it tries to boot, then looking up the last one in the manual might give you an idea where it's going wrong (the motherboard might also have some other helpers, like LEDs next to critical components which light up as they go through POST).

Looking at the manual on Gigabyte's site, it's in the appendix at the end (p43). Code AE is "boot to legacy OS", which means it's completed POST and can't find the OS, or that it's hasnded over to the OS bootloader..?
