Motherboard Dead?

[Grennyfell97]

I pulled apart my computer yesterday to clean it out and reapply thermal paste to the cpu. After re-attaching the heatsink and cooler, putting the GPU back and connecting all the plugs again I put it back on my desk to power it on and then nothing happened. It would not power up at all. I tried jumping the power switch on the board. I then did the paperclip test on the 24 pin connector and flicked on the power supply (I left the cpu plug in) and the fans and lights came on, but it doesn't do anything when trying to start it any other way. I reset the CMOS, I tested as much as I could on a different motherboard, the gpu, memory, psu are all fine. Its either the cpu or the motherboard, but I don't have the resources to nail it down to which one is the culprit. I would assume its the mobo since there was nothing that I did that would damage the cpu in anyway. The cpu is a 4790k sitting in a MSI Z97 Guard Pro. My question is, should I try and find someone selling an LGA1150 board which has now been retired for roughly a year and most are second hand... Or should I just go out and buy a 7700 on a decent B250 board and get myself some DDR4 memory and then sell the 4790k and the 16Gb of memory that I had with it?

 

Any thoughts anyone?

Probably upgrade to something like 7th or 8th gen. The motherboard Is probably (most likely) dead, does it start and shutdown immediately after pressing the power button and have you tried to contact MSI?

Absolutely no sign of power at all when pressing the button, or shorting the power switch jumpers. I did drop my screwdriver when tightening the fan mounts which is why I don't think I'd be able to get anything out of the warranty or MSI.

Well, MSI doesn't need to know that. ?

 

By dropping the screwdriver on your Mobo you probably chipped a ceramic capaticor which explains why it's not powering on.

Step one is to completely remove the motherboard, and all motherboard attached components, and re-install like you're building it for the first time, paying close attention to mount points and connections.

 

It could be as simple as a screw fell behind the board and is shorting something, or a plug isn't properly making contact.  Start with bare minimums (MB, Ram, CPU, Graphics, PSU) and if it works, then add in each component after that.

I did all that. The only screws I removed were the CPU fan and heatsink screws. It had been un-touched for about a year so there's no screws rattling around. I've taken the board out, there's nothing out of the ordinary. The PSU, Graphics card, and memory all worked and posted when plugged into a spare AM3 board I had in the house so its none of those.

Even then, I dunno what they'd do about a discontinued board for 4th gen processors. So I guess the question is do I go a 7600, 7700(k) or an 8600k (8700's are a bit pricey.

Then what could possibly prohibit it from booting? I can't think of anything. The only thing that comes to mind is that the MOBO is dead... Like dead dead, no reviving it.

I recommend the 8600K. It's overclockable, has 8 cores and 8 threads (4cores more than the 7600K) and is more up to date.

 

edit: is the board still under warranty? If so why not give it a shot?

I could, but I am also thinking I could just make the change to DDR4 and get a board with a PCIe m.2 slot. I should be able to get a decent chunk of money back selling the 4790k and the 16gb memory.

6 cores 6 threads******

You could do that too, and that's a really good option. But if the CPU is also dead...
