CPU or Mobo dead, did i just kill 2 PCs??!!

Hi all,

 

I built a PC for a client yesterday, all was going pretty good until i turned the thing on:

 

I got no video signal, so i checked if i forgot something, and also reseated the memory, and checked all cables -> everything seemed to be fine, so i tried again, same result!

 

I disassembled the thing and built it on the MOBO Box, plugged in a system speaker, used only one DIMM in the recommended Slot, reseated the CPU and used the onboard Video, no beep, no video!

 

So i cleared the CMOS, but that also didn't do the job!

 

I pulled out the memory to test if i would get a Beepcode -> I got 1x long 2x short which is no memory installed!

 

Tested it the other DIMM, still not working!

 

Then an idea came to my mind, and after i did it i think it was sooooo stupid -.-

 

I pulled out an other PC i had around, also Skylake DDR4 but an OEM PC, tried the memory in my problem PC (Standard Samsung DDR4 8GB) but it didn't help so i switched it back!

 

Then i installed the i3 of my problem PC in the (2 weeks ago working) OEM PC and turned it on, no beep no video! :o

 

OK so the CPU is dead i thought, switched the OEM PC back to the original i5 AND what happend -> no video, no beep, Fan spinning fast! WTF

 

Now i have tried everything that came to my mind but i just can't figure out whats the source of my problem, i mean it seems to be the CPU but i didn't try the OEM PC after i switched the memory, so the MOBO also could have killed the RAM?! And i can't belive that the CPU killed the OEM PC???!!!

 

Specs:

Power problem? Probably?

Thank you for your reply!

 

I don't think so, the OEM has a diffrent PSU that i know for a fact is, is working fine, and the grid is also fine beacause my other PCs are working without any problem!
