Question Help to determine if CPU is dead ?

[Od86x]

Hi guys .. I have a problem..
Last August I build a new PC..

I7 10700k
Rtx 3070
Asus Z590-P Lga 1200 Motherboard
16 g Ram

It was working fine .. but suddenly yesterday I turn on my PC and it did start up but no monitor wake up and there's is no starting beep from system ..
Now .. does that mean CPU is dead if there's no beep sound and black screen .. ?
Or what else it can be .. ?

Inside the PC case RBG lights and fans are ON when PC running but its doing nothing ..Black screen and that's it...
Please advise me what to do & what to check before I contact online store for replacement ??

Did you try clearing the CMOS?

Nope. It means somethings not working, but it could be any component at fault.

Please advise me what to do & what to check before I contact online store for replacement ??

You need to find out which component failed (unless that would be prebuilt system). Now, I don't suppose you have replacement parts, so that limits your options. The first thing to do is remove graphic card and connect monitor(s) to motherboard, then check if the system will start.

Sorry for delaying..
I cleared CMOS by removing battery and shortened contacts ..as manual says ..
Still same nothing .. Monitor won't turn on.. and no beep sound..
I dont know what it can be ???

 

[Od86x]

I assuming it at least should beeping if anything wrong ..but its doing nothing... no sound ..at start up by pressing power button...
Before was everytime ...

 

[Od86x]

And I removed GPU still no luck..same ..
That's why I thinking... my PC are without sound and no monitor wake up ..and Reset button doesn't do anything ...
Should I get and measure temp at my CPU if its working...?

 

[DRagor]

And I removed GPU still no luck..same ..

Next step is to remove RAM sticks as well. If the motherboard is fine it should beep no-RAM error code at the start - but if it's still silent you have a real problem.

Yes .. I removed RAM sticks... and now my PC finely beeping.. non stoping...
So what's that means ? Faulty memory ?

Have you tried booting with just 1 ram stick in the 2nd DIMM slot?

Not necessarily. But that's a good sign, we're moving somewhere. Now, install just one of the RAM sticks into A2 slot (second from CPU) and boot. If that will not work, do the same with another stick.

 

[Od86x]

Will try now

 

[Od86x]

Ok ..it worked.. I got my PC boot as usual .. into windows ..
I tried with 1 stick .. ant slot A2..
So what that means ?

It means this stick is fine. Now try the other stick - I assume it will fail which would mean you have a failed stick. But there are other outcomes possible so please try it first.

It is the RAM (unlikely) or your mainboard then.

I would then try RAM using in different configurations. Try the same single RAM in A1, if it does not run then probably there is something wrong in A1, and try the other RAM in A2, if it doesn't run then that RAM is faulty.

 

[Od86x]

Alright I just tried other ram stick in a slot A2 and it worked also..my is PC running ..
Any suggestion ???

Both sticks are ok, so this is a problem with mobo slots OR CPU. We need to check the mobo slots first. Which slots the sticks were in originally?

 

[DRagor]

my pc is also running when i use only slot A2 i dont know whats wrong motherboard cant be coz i changed it yesterday

Please make your own thread about your problem. List your components, symptoms, and what actions you have done already and what results they achieved. Because I doubt your problem is exactly same and therefore will have different solution.

 

[Od86x]

My sticks were in slots A2 and A4..
Btw I buld this PC myself...

There is no A4 slot. Only A1, A2, B1, B2.

 

[Od86x]

There is no A4 slot. Only A1, A2, B1, B2.

Yes yes sorry
I mean in a 2nd and the 4th slots my ram is ..
Sorry

 

[Od86x]

In order coming from CPU

Ok, So the current working theory is that 4th slot is not working. Put your sticks in 2nd and 3rd slot, and assuming system starts check in Windows Task Manager if it correctly sees all 16 Gb RAM. If it does, try only one stick in 4th slot - and if I'm correct it will fail.

You should try 1 and 3. So the RAM can run in double channel. 2 and 3rd slot cannot run double channel.

It does not matter at this point, we are trying to find what's wrong with OP system, not to make it work optimal.

 

[Od86x]

Hmm wow .. its working ..all ..
I tried first 4th slot ..and my PC booted as usual..
Then I installed my GPU and back my memory in original slots and my PC worked as it should...
Must be disconnected some how..
And guys I forgot to tell you couple days ago I repositioned my PC to other corner of the roome ...
Didn't think that that could be a problem...
Thank you guys so much for help..!!!
Thank God we have THG forum !
I let you know if something will change..
Thank you again guys !!!
