I got shock by my CPU, now my PC doesn't boot, does that mean my CPU is dead?

[tienlp]

While replacing the new liquid cooler my CPU accidentally fell right into my palm (yes I had to remove the stock CPU holder) and I felt a small shock, now my system only boot for a few seconds before shutting itself off and restart (then restarts few seconds later), fans were running but no signal to monitor, keyboard or mouse.

That's crazy but yeah, you very likely fried the CPU with your static electricity. That's why we use wrist grounding straps to prevent the build up of static electricity.

Bad news m8: it's dead.

No power at all? I'd check over all your cables before declaring CPU. Even a dead CPU, or no CPU installed should not cause no power up situation. Modern motherboards(certain ones) can flash the UEFI with no CPU installed in the board. I would think your system would still power on, just no POST or just hear beep codes.

If system is powering on, but nothing else happens, then ESD likely did kill your CPU. When you"feel" the zap, its a minimum of about 2,000v of static charge.

I grounded myself and kept me grounded every 1 or 2 minutes, the CPU was on my hand, is that even possible to discharge electrostatic to the CPU? 🙁

my motherboard (Giagabyte GA-H81N) doesn't have an external monospeaker output so I couldn't know if it's done the POST or not, but as fair as I know the keyboard and mouse LEDs didn't lit, no signal to the monitor either.

Case fan, CPU fan and VGA fans did run for a few seconds before the PC shuts itself down and turn on again.

You put in your CPU since then, a lot of things could have gone wrong. Your CPU power cable may not be plugged in all the way, a power strip may be turned off, or you may have bent a pin.

Do you know anyone who has a CPU with the same socket that you could borrow and test on your system?

Check your motherboard inside the case, make sure its securely in, make sure the screw drivers are not too tight or too loose on the mobo.
Remove the gpu and hdd/ssd only boot up your computer and tell us what happens.
I don't think your cpu is damaged at all but something inside the case maybe shorting out the mobo.
If worse comes to worse run it by geeksquad or a computer shop speak to the lead technician and tell them you want to test the cpu.

I took a photo of the sockets, looks like I bent *some* of them when putting back the CPU right?

 

[UnspokenWhale]

That's probably the issue right there. It's possible to carefully straighten them if the effected pins are still attached. I have not done this personally but there are lots of guides on the internet on how to do this. If a pin is permanently damaged you need to replace your motherboard.

 

[Ecky]

A sewing needle is your best bet for straightening those. I've fixed sockets with bent pins but it's very fine work.

You have 3 of them which are bent, before you attempt to fix it yourself and screw it up any further.
Contact the mobo manufacturer for help, ask them what they're policy is for bent pins and how many you can have before they tell you no for RMA help
With amd chips, if 5 or more pins are damaged amd will refuse to replace it and void your warrenty over personal damages.
Take a picture underneath you're new cpu as well make sure it is unmarked and not damaged.

Bummer, somehow I've made it 20 years without ever doing this.

I got a call from the repair shop today, he adjusted the bent sockets and the PC is bootable now, but he said there are some few more tests to do before concluding the status of both the mobo and the CPU. But at this point I think it is mostly caused by the bent sockets. Thank you guys

Edit: all the tests passed, it's the bent sockets that created the boot loop

Next time becarefull when installing your cpu.
