PC Suddenly Won’t Boot Up

So I tried what you said and I now am only with a cpu, cooler, and ram installed and still no boot. The green light on my mobo still flashes once no matter what whenever I flip the on switch on the psu. Could it be a faulty front panel connector from the case?

And again, NO case either. Your note about the front panel connector makes me think you have more parts to eject.

Again, we have to at times get down to just two parts and then we know it's one of those.

If you didn’t connect the front panel, how would you power up? Sorry if the questions are repetitive, I’m a beginner.

We don't want the case yet since so many new builders short out the motherboard with some extra mounting post. If we are lucky the motherboard survives.

And yes, some new builders will ask why it shorted out later.

So I am left with just the cpu and psu plugged into the mobo and when I jump the two power switch pins together nothing happens.
Does this mean I somehow fried the motherboard? I got a warranty on it if that’s the case.

The light on the motherboard still flashes green when I turn on the psu, so could it just be the pins or something causing not to boot but some parts of it still work?

When you reduce the parts to the bare minimum then the bad or misconfigured items are what's left. It may be one or all but at 2 days old you have a warranty so RMA the motherboard for another now.

As to the parts of a motherboard that work (the part that flashed green) it does no good to get into that since the motherboard is not repairable except at the maker's repair sites. This may upset some that I don't hold classes on electronics but that's a multi-year study that I can't condense here.

Am I able to just unplug everything and get a new one with no problems? Cause I already installed windows and updated all the chipset drivers on an ssd so I can just plug everything back in and just update again right? Thanks for all the help by the way!

If you've replaced the bad parts, that is what usually happens. BUT I've seen new builders leave in the mounting stud that shorted out the board and they can burn through boards until they are denied RMA due to them burning up boards.

You wrote you are new to this so how can I know what you know?

Also, Windows does NOT like motherboard changes. If it's the same make and model it may still balk if you activated your copy. That won't stop you from using it but involved a call to Microsoft to tell them what happened and get a new key.

I know a little bit just from watching building videos the last couple of months, but I’m not sure what you mean by mounting stud?

Also, I haven’t put in a key yet so I’m running on inactivated windows right now. So would the best thing to do be wipe the drives and do a clean install? I only have a few games installed before the shortage happened.

I don’t think I could cause wouldn’t it detect I already have a copy of windows installed so what would I do?

Motherboard standoff or mount.

As to the wipe since it's not activated and it's the same motherboard make and model it's up to you. For me I would since I don't like any ambiguity or chance it can cause issues later.

As to your Actually post, I can't decode your question. What are you asking?

So would I just exchanged the motherboard and do the exact steps I did last time to assemble it, just being more careful to not static shock it which is what I assume I did?
It should just boot straight to windows again right? And if I don’t do the wipe of the drives, will it automatically update the drivers like last time or will it keep the ones I already have installed?

By leaving in the mounting stud, do you mean like screwing it in too hard? Cause the motherboard didn’t have one installed when it was in the box.

The motherboard does NOT have mounting studs installed. These are installed to the case and the motherboard rests on them and we then install some mounting screws.

Again, new builders often have too many mounting posts and that creates a problem either right away or later.

It's not funny as the new builder asks "Why did it work for weeks, days, or years?" It was incorrectly built. That's the end of this.

If you did the same steps and left an extra mounting post the problem would repeat. This is a very common assemble mistake by new builders.

As to the boot to Windows you are asking me to predict the future which I can not do. It should be fine but hey, Windows. As to the drivers, Microsoft is not known to leave drivers untouched unless you change a setting which we only do in very special situations which this is not one.

Welp I think that solves everything! Thank you for all your help on this, I think I’ll just wipe both the drives when I install the windows!
Again, thanks a lot!
