MOBO/CPU Upgraded Replacement

[Bazooka_Joe]

Hello, 

 

Recently my computer randomly shut down and now refuses to post, giving error code "00" on an ASUS Maximus Hero VIII with i7 6700K. 

 

The PSU tested fine with multimeter hitting the 24pin connections and ram also seems fine. Breadboarded system with minimal components. Same "00" error code even with no ram present. (I would expect mobo to throw a specific RAM errow if no RAM is installed) This led me to believe the MOBO was bad rather than a bad CPU. 

 

My first thought was the MOBO was bad. To confirm this I made the mistake of buying an ASUS Prime z390-A thinking it was compatible with my i7 6700k. (Its not)

 

Unfortunatley the z390-A is not compatible with my i7 6700k. Now im stuck with my old Hero VIII board and a new z390-A, both of which do not post with the i7 6700k cpu. (z390 for obvious reason, because CPU is not compatible.) 

 

Now im back to square one of not knowing if its my Hero VIII mobo or i7 6700k that is the culprit here. AND I now have an extra z390-A board that im not using. 

 

I am trying to decide if I should just keep the z390-A I bought on accident and get a new i7 9700k, or, hope that my old MOBO is still good and order another i7 6700k and hope its cpu the that is bad. Unfortunately I do not know if its the old mobo or old CPU which is bad at this point. However, regardless, if I want to repalce either with an upgrade it appears I will need to infact upgrade both. As any processor better than the i7 6700k will require a newer MOBO. And most newer MOBO's will not support the i7 6700k (I may be way off on this).

 

I'm in a weird spot as it seems im at the top tier of the previous hardware generation and now in a spot where I need to upgrade either my MOBO or CPU as one of them is dead. It seems like im going to have to upgrade both regardless, if I choose to upgrade one. Otherwise, I would need to reorder the same, old cpu or motherboard. 

 

Any tips are greatly appreciated on what the best option forward would be. Don't really have a budget, but also have no need for anything too extreme. Looking to stay at about the level of an i7 9700k. 

 

Thanks!

well one thing I can say is that it's very uncommon for cpu's themselves to fail without them being overclocked very high or overheating several times. theres about a 90% chance it's the motherboard and 10% the cpu thats at fault

I live near a Microcenter. I can return the Z390 and pick up a combo they offer for $530 which is an i7 9700k and the same Prime Z390-A board. 

 

Not finding any realistic replacements for the Hero VIII and its looking like an upgrade is going to be the way to go. The board is 4 years old and was constantly ran. I think an upgrade is the most realisitc approach here. Then I will ahve the old i7 6700k for a 2nd/side project build.
