used CPU is giving me blue screen of death

[Romano]

Hi guys, I purchased an used i7 3770k to replace my 2600 non-k, today it arrived so first thing I did was: removing the old cpu installing the new one, applied some artic silver thermal pasted, mounted the corsair AIO and turned on the machine

 

 

a screen appared telling me a new cpu was installed press f1 for bios to set-up, so I did and then pressened F10 and saved changes (i didin't knew what else to do)

 

After it booted I ran Aida64 with stress test, it ran like 2 minutes at 100% with 75º (corsair pump in performance and fans at performance)

then it crashed I was NOT overclocking just stock settings and boom blue screen of death

 

Restarted the PC and ran PUBG, it ran well for 3 minutes before going to the plane phase it crashed again blue screen of death

 

I will run it again to take a picture of the error, I'm sorry I don't have it yet but will update ASAP

 

please help!  I never heard of a broken CPU

 

EDIT 1: Opened Aida64 to stress test again to take the picture of the blue screen error and saw this in the program:

Did you update your BIOS before installing the new CPU?

I did not, I think I have the latest version since I upgraded long ago, tonight I ran Aida64 for 44 minutes it was stable with ok temperatures

 

after that, played two matches of PUBG without any problems. 

 

Today I turned on the PC and ran Aida64 for almost 2 minutes, it reached temperatures of 85 and 90 so I stopped the test fast, what is happening?

any help?

 

the last test I made it reached 100ºc I had to take the picture with my phone since I knew it was about to crash but for some reason, it didn't

So I removed the pump, cleaned and re-applied the thermal paste from a different tube of artic silver this time, a little less paste let it sit for about 2 hours and turned on the PC

 

I connected the Sata plug in a different one this time

 

Temps on Aida64 are 70º to 75º and idle: 45º - 50º

 

Still no hot hair from the radiator only cold 

 

What can I do? I have the stock cooler that came with the cpu but I don't think temps will be lower with it at 100%
