Hi.
I'm fairly sure my Motherboard is on it's last legs, and I need a replacement. This post will be divided into two parts since it's fairly complicated. 1. describing my problem and seeing if you agree with my assessment that it's the motherboard that's broken. 2. Listing my requirements for a new motherboard. I'm currently using the Z170 classified mobo. Anyways, let's get on to it
1.
My computer used to work completely fine. However, a while ago, when I tried to turn on my computer normally, nothing happened. And it's been like that ever since. However, I am able to "kickstart" my computer by fiddling with the PSU power cable as I "spam click" the on-button. Essentially, if I'm able to click it as I hear a spark noise from the PSU (which usually requires a lot of fiddling. It can take me several minutes to get it running), it'll kickstart the computer and it'll be able to boot. My first thought was that there was something wrong with the PSU. However, I've tried another PSU and it is not able to boot my computer either. Secondly, I don't believe something is wrong with the case power button, as my on-board power button does not work either. In addition, I'm able to shut DOWN my computer with my case power button. I've also tried to use a different BIOS load out, but with the same result. As far as I can see this should be a motherboard issue, unless someone else have a better idea?
2.
I'm running an Intel M.2. NVMe hard disk (Intel 750 2.5" PCI-E 3.0 x4 SSD - 1.2TB) (EDIT: Actually, it's a U2 SSD, but using an adapter to the M2 key M slot), so I need a motherboard that has support for this.
I'm currently using a 1080 graphics card. It would be nice if there was space for a SLI setup as that is potentially going to happen down the line.
My CPU Cooler is fairly big (Noctua NH-D15S with two fans), so there has to be space for gpu/memory taking that into account. Although the cooler does have an "alcove" to accommodate memory.
I'd love if the Mobo has some standard on-board USB2 connectors. This is what I'm missing the most from my z170, as I'm unable to plug in some components due to the lack of these. It's not an absolute must, though.
The processor I'm running is Intel Core i7-6700K Skylake.
Preferably space to use at least 4 ram sticks.
Would my best option be to just buy another z170? Or do and of you guys have a better idea?
Thank you for reading this far
Edit: Forgot to mention, price isn't really an issue unless it's completely insane.
