Case failure?

[Dan087]

Why would a computer work outside the case but not in the case?

An electrical short. Not the only reason but it could be one of them. Are the standoffs underneath the motherbaord installed and in the correct positions?

[Dan087]

I think so?

[Dubious]

Probably not then

[Dan087]

What would you look at first?

as said make sure all the standoffs are in the case and fille so the board is not hitting the solder points a the back of the board. 

 

if that is it then its got to be something causing a short. add things one at a time ie motherboard an cpu in the case only do a jump to start (do nto use the power button or hook up any usb reset or hdd indicator light etc.) then one at a time add the power switch, then the reset switch then the indicator lights. 

 

That said I find the most common issue in "cases" causing issues is a bad USB header. while they cost quite a signifigant part of case construction they are probably usually the lowest quality part on the box. If a manifacturer can put cheap usb2.0 or 3.0 ports on the front vs quality ones they can save a lot of money looking at retail alone the difference can be $10-15 for quality usb port add in cards vs ali express cheapos (that i would not put in my case)

It’s a shame you can’t keep the board outside the case!

nothing is stopping you from doing that. 

 

I built a friend a cheap gaming pc with part i had laying around that were basically for diagnosing PC issues. its literally mounted on a sheet of plywood and still running like that. granted i would advise liek a box fan or something to cool motherboard components be pointed at it but it works just fine

You can, most call it a "test bench". Back in the 90's I mounted my motherboard to the bottom of my desk because I was always testing parts and stuff from the shop after work.

 

Check the main power connection and the power connector for the cpu to make sure they are seated firmly. Then check to make sure the power switch connections and stuff are hooked up right. If its none of those do what Goofy said and pull the whole thing out again and start over testing things one at a time.

Always a short or grounding problem. 95% of these are caused by improper standoffs.  Volcano "Dimple" motherboard trays are notorious for this.
