I actually did upgrade to 11th gen becase of this incident.

how do you even know you had a 7700k to begin with? The major difference is the K is unlocked so you can overclock it. If you were having issues and you had increased the clock speed, wile troubleshooting its they likely set the clock speed back to default. So either you had a non K version, or you are judging it by what the clock speed is showing and they may have set it to default?

Follow up question, if you knew enough to know what exact cpu you had, why don't you do the work yourself next time? I'm sure with a little help from the internet you could have replaced the motherboard yourself.

Have you even tested it? You say its probably broken. For what its worth, unless you were overclocking the 7700k you literally wont notice any difference with a 7700. And there is no way a 7700k is 450 euros. That's the price for a brand new 12th gen i7, not a used 7gen lol.

This is a 5y old CPU, in 2017: I7 7700 msrp is 303$ I7 7700k msrp is 339$ (Source: Google) On second hand market you can find both for under 170$ or equivalent in euro. OP: I lost 450$

Also OP: complains in Reddit instead of going to the store and talk with fellow human

The BBB is a toothless organization looking to sap money from clueless business owners.

Please don't "blow them up online" like people are saying... If you have no evidence of them taking parts from you and the place is as scummy as they seem then I doubt they would have issues with taking you to court for defimation.

To those that down voted me the edit OP did proves why you shouldn't just blast people online..

Contact police and file a report for theft

and my Sharona

This is ususally where violence comes in... Not kidding.

>After that contact the better business bureau

If you want nothing at all to happen.

The BBB is so last century.

I see plenty without politics...

Maybe they tested if the cpu was malfunctioning and forgot to put the original back.

Give em a chance to behonestly mistaken.

But yeah, i can completely relate to the helpless amger you go through

How do we know? All we have is OPs story with vague claims like „probably broken CPU“. How is a CPU probably broken? And even if so, get the fuck back to the shop and talk to them about it.

If the shop indeed is at fault, contact the police.

OP should probably check his local repair shop. They probably have a cheap used 7700k in stock right now!

You have recourse. But it will require a lawsuit.

EDIT: Also do as others have said. Blow up all the review sites.

I believe there is quite a difference between sounding innocent and being innocent

Aite hector the garbage collector, relax

As long as the OS wasn't reinstalled you can still see devices in Device Manager that are no longer attached to the system by enabling an environment variable (set devmgr_show_nonpresent_devices = 1), then enable view hidden devices. Once you do this look at the properties of that ghosted out proc, then on one of the tabs (details?) See if it lists any proc specific identifiers like a serial number or CPUID. This will give you something at least. Best would be something like a receipt of purchase, but the issue is not if you have, or had, or ever purchased the processor, but rather proving that the specific proc was in fact in the computer when you turned the device over to them.

Its honestly comical

I miss 20 seconds ago when I hadn’t read this post. I cringed in sympathy pain, and I don’t even have a penis.

and my bow

Go back and find your receipts from when you purchased it. Hopefully you have an email somewhere. If you can show Police that you at least had purchased it (even though it doesn’t prove it was in the computer at the time) it may bring some validity to your case. I’d still give it a shot regardless, its good to have some documentation. Furthermore you should write an accurate and complete review of his business on every website possible.
