PC won't start.

I was uninstalling the Noctua D15 to install a aio and my cpu came out with it. At first I looked at it and it seemed fine. I installed the aio and my pc won't start now . I don't even have an error code on my mb. The light on the motherboard don't come on either. Do you guys think my cpu or mb is ruined? Thanks for the help in advance.

My specs are

ASUS Crosshair Hero VI
EVGA 1080TI SC Edition
Ryzen 1700
EVGA Super Nova G3 850 Watt
G Skill Trident Z RGB 3200 16GB

the dreaded pulling out heatsink and cpu came out along with it disaster.

outlook looks grim, not many things survive that kind of yank. did you take pictures of the cpu pins or socket when that happened?
no siggy, saw stuff that made me sad.

Maybe I have been lucky but I haven't had a CPU or motherboard die on me from that situation yet and I have been there more than a handful of times. How did you remove the Noctua? Did you lift it straight off or did you pull it to one side? Were there any bent pins on the CPU? A credit card can be a great thing to straight out pins at times. If there are pins that were left in the socket when the CPU came out, then more than likely the CPU is toast. Most sockets do survive CPU's being ripped out unless the socket came with it. Did the socket come off with the CPU?

I guess it did have some bent pins. I was just using some tweezers and jiggling them around I did not really know what I was doing, but it worked? lol I put my CPU back in the socket and now everything works fine. Thanks for the help guys. Also do you guys have any tips for not ripping the CPU out with the motherboard when uninstalling a heatsink?

Hi MichaelGivens.

You just remove the screws or however the heatsnk is attached and carefully remove it, the cpu is held in place with the latch, it won't come out until you unlatch it.

It did come out for that user while the latch was closed, that's the point of this thread.

warm them up before trying to yank it out. cold boot yank is probably a bad idea.

once you need to pull heatsink out for whatever reasons, try to get a feel, whether it "felt glued tight". pull heatsink up vertically (not too much force), check for resistances. you can already feel it's stuck if it takes more than average force and it still won't come off.

at this point, it's probably to wiggle them slowly like you're trying to turn a knob, once the heatsink slides, pulling it out is much easier.


last: don't use that TIM. i bought a cheapo TIM and my first Phenom II X4 got stuck to heatsink. bought expensive TIM and the thing never happened again, even after 1 year application, removal was easy.

If you think the CPU is going to come out with the heatsink, pull straight up. At least you won't bend the pins that way. As someone mentioned, a warm CPU lets go of the heatsink easier. Run a burn in or stability test on the CPU for about 5 minutes before shutting down and attempting to remove the heatsink. It can make a difference.

Fixing CPU bent pins varies by CPU. On the 8350's, I used the card that held my phone's SIM to ensure all of the pins were straight. It fit almost perfectly between each row, making it easy to see which pins needed a slight adjustment or needed to be corrected. More pins means you will need something thinner. Just slide it through each row of pins, making sure you go both directions because pins need to be practically straight.

i have a name (nick), 😞
oh well.

we differ by philosophy on the methodology to remove stuck cpu. i'd prefer a more cautious-finessey approach, though admittedly it'd take much longer to coax them to separate with each other.

if you prefer direct vertical yank, gambling on pins not bending, and that it works, i suppose i can't complain.
