Haswell CPU

[The Belgian Waffle]

Hi guys,

Long story short, I've tried at a computer store to change every component but the CPU in my machine and it straight up wouldn't give me any monitor signal, even tho the fans are correctly spinning.

 

I'd like to pick up a cheap 4th generation i5 CPU to replace this one if it's actually dead, but since I live in Belgium there are little to no options.

Do you guys know where I could pick up one for cheap online?

 

Thanks

I would get this if you can overclock:

but this is the cheapest lga 1150 cpu i can find eu

What motherboard are you using now? And was this system running and suddenly stopped working? Or has it always been a no POST?

I bought the entire system from a guy who apparently didn't take good care of it, since when I cleaned it the first time it smelled like smoke and there was dust everywhere and the CPU was running at 90°c at freaking idle.
 

So the thing is it used to post, but not every time, so sometimes there was video output only from the mobo, sometimes it was good and booted correctly and I could see my screen through the GPU, and sometimes I couldn't see my screen at all, even tho I was connected and into my windows session. I could hear the update sounds, the USB sticks sounds etc, but no screen.

I took it to a specialised shop that looks like a LTT warehouse but smaller and we changed every piece of hardware but the CPU.
Yesterday evening the CPU probably died while stressing it too much from changing everything, but it was probably almost dead.

And to answer your question, the board was a Asus H81M something, and the second board I tried is an Asus B85MG

Wow. Harsh life. So maybe thermal damage then. Seems odd that it presented as an intermittent issue at first.

 

So did it work for a while on both boards and then start to fail? Or was it an immediate issue even on the new B85 board?

It worked for like 3 weeks on its original board (it's a pre-built system and the guy added a 660 Ti on top of it.

 

I tried to find a pattern, maybe the onboard graphics and the dedicated graphics do not communicate well on where the signal should go through so I tried a bunch of different things (I obviously didn't plug in the GPU while it was on ), but there's no evident pattern : Now, it straight up refuses to boot on any board that I use.

I also noticed than, on the original board, the case fan that was attached to it stopped working, while in the other motherboard it worked and also, in both boards, when I plug in my mouse, the lights don't come up.

 

I'm not having a fun week, tbh

I can understand that.

 

So it worked on the old board then failed and the new board didn't work at all?

Yup

Is it at all possible; since the B85 requires BIOS version 0904 to support the 4460S, that it's simply the case of needing a BIOS update? Because that's honestly what it sounds like.

 

Let me sum it up.

 

Original board failed, probably due to heat issues and age. You've swapped every component but the CPU, including the motherboard and it continues to spin fans but not POST.

 

Can you take the board back to the store you got it from and have them apply the latest BIOS update?

Yes, that's it.

It's actually a friend that gave it to me to test and see if the motherboard was the problem, because that was my original thought after seeing that it wasn't the PSU.

He told me he used it 6 months ago and it was with a i5 4440. He wanted to sell it but he eventually forgot.

Ok that right there pretty much seals it. 4440 works on BIOS 0501 and the 4460 requires 0904. So if your friend never updated the BIOS then that is why your 4460 is refusing to POST.

 

Or the CPU is dead. Either way a quick BIOS flash is worth the small cost in time it will take to try.

 

You'll need an older Haswell CPU like that 4440 to flash the BIOS.

Ok... So I might aswell bring the board back to him and ask him to flash the bios.
Isn't there any way to do that in another way than using the board itself?

No other way. You need a CPU to flash the BIOS. More expensive boards have flashback abilities that allow you to flash without a CPU, but not a B85.

And.. Isn't there any way to check the Bios version other than booting the thing up?

 

But what does happen if I boot it without a CPU? Will it tell me anything or straight up black screen?

The release date for the two Bios versions is the same and he bought it like a month before that, so how could he use the 4440 with that same board?

Board could have been sitting on the shelf for a while. Depends on what it shipped with.

 

Like I said its a gamble. The board could have a completely up to date BIOS and the CPU is bad, but I think it's worth a shot.

Yep. What will happen if I boot the board without a CPU? Black screen I imagine?

Yup you'll get the same thing you are getting now.

Well.. Yeah, it's definitely worth a shot like you said.

 

My buddy doesn't seem very "in" with this kind of things, so I might wanna grab a pentium somewhere that uses the same Bios version as the 4460.

Or maybe if I find a deal I can just buy 4440 and sell the 4460s afterwards if it works

On the motherboard there an "0705" written alongside the motherboard's name, which corresponds at 1 Bios version, which, if they use some kind of logic, came out before the Bios version I need to be able to use my CPU
