Computer Help Needed by Whitewater Woman, please

[WhitewaterWoman]

This is the set up I am trying to get to work. All the parts were working flawlessly in my office (where I no longer have internet.) I have moved them to the main room in my little cabin.

Here’s an overview, followed by details.

The CPU is a small 5 inch square block that was recommended to me by cberg, some may remember him from WP. It’s running Windows 11.




The keyboard is a standard extended keyboard. It is wired to the CPU. The mouse is battery operated wireless and its little receiver is plugged in. I just changed the batteries.

The monitor is an LG, large, probably 24” on the diagonal. It is plugged into the CPU with its special plug. It is wired to the CPU.

CPU is plugged in and lights are blue.

I have checked all the electrical connections and they are on tight. Wireless is not set up yet, but that shouldn’t interfere with the monitor’s ability to display.

When the CPU is on, and I turn on the monitor I get two messages, the first and then the second. And then it shuts down. I’ve tried pressing various buttons on the keyboard that might be OK to no effect.

Any suggestions? Any help is greatly appreciated

 

[Tired]

Is there an OK button on the plastic part of your monitor? Normally there are some small buttons under it on the frame, typically right corner.

 

[Shamar]

Monitors often have several inputs, and the correct input has to be selected. There ought to be a setup button, as Tired said, usually under the lower right corner, near the on/off button. Once set configured, the monitor will remember the setting when turned off. If you are using a TV instead of a pure monitor (there is not much difference between the two any more) you may need to use a remote to set up.

 

[WhitewaterWoman]

Thank you Tired and Shamar.

There are no buttons anywhere like Tired indicated. There is only one button and it is the on/off button. I have turned the monitor every which way: no other buttons.

I’ve taken photos of the plug in places. Maybe I have something in the wrong hole.

Thank you.

That's my thoughts too, you just have to tell the monitor which input it's supposed to be displaying. In the first message it's telling you that it found something connected and is asking if you wish it to display that.

Your monitor might be like mine - no little buttons around the edges of the frame.

Instead there's a little wobbly toggle thing that you press once to activate the monitor's menu, then you can move it up and down or side to side to navigate that menu.

Here's a picture:

If your monitor is like mine the button in this picture isn't "just" an on off button. Try pushing it side to side and up and down.

 

[WhitewaterWoman]

Thanks. I’ll try moving the little button around.

I get the monitor is asking me to do something, I just don’t know how to implement its request.

I’ll see if it prefers side to side and up and down. Thank you.

try moving the cable on the monitor to the next one, the HDMI IN 2... if that does not work, maybe we need pictures of the back of the CPU. where you connect the cables.

 

[WhitewaterWoman]

Thank you, all.

By jiggling the on/off button in a variety of ways, the monitor suddenly decided to work. Hurray!

And I've got it connected to the internet!!! I'm on a role.

However, when I try to go to a specific website, ALL the browsers: chrome, firefox, and Edge refuse to let me go any further stating:

Your connection is not private
Attackers might be trying to steal your information from www.google.com (for example, passwrods, messagres, or credit cards.) Learn more about this warning.

NET::ERR_CERT_AUTHORITY_INVALID

But there are no such problems signing into websites from my windows laptop or ipad or iphone.

Any suggestions as to how to get my windows CPU to behave?

Thank you so much.

NET::ERR_CERT_AUTHORITY_INVALID

But there are no such problems signing into websites from my windows laptop or ipad or iphone.

There are potentially a number of steps as shown in this link to try to solve such a problem. Most of them look fairly simple to implement, assuming the problem is on the client end and not the server.

How to Fix the NET::ERR_CERT_AUTHORITY_INVALID Error

 

[s3_gunzel]

NET::ERR_CERT_AUTHORITY_INVALID

Check the date and time on your computer; certificates are issued for a time period. If the time and date on your computer don't match the times and dates for certificate validity, you'll get an error. Most(!) websites, especially Google, should have current certificates, so if your date and time is the same as the current date and time, you shouldn't have an issue.

If the computer has been sitting for a bit it may have lost its time sync, and its battery (little button one, not like a laptop) would have died, which would result in the clock not moving forward until power was applied again.

 

[Hypnalis]

"CERT" in this context is related to HTTPS (the S implies encryption or crypto-based verification on the connection).

Both ends of an HTTPS connection need valid X.509 certificates, which are small blocks of data (perhaps as text files) "inside" your web browser that you can probably find in your browser setting displays, but it probably isn't worth the trouble.

Every cert contains fields that display like this (real example):
Validity
Not Before: Sep 10 00:00:00 2025 GMT
Not After : Oct 11 23:59:59 2026 GMT

If your computer reset to e.g. Jan 1, 1980 when you moved it, HTTPS might pop on the "Not Before" date.
Check this first.

If the system time is ok, try:
* Find your browser's cert list. Empty or nearly empty is bad. BTW most/all of the certs your browser is using locally were installed "automagically".
* See if there's a browser setting that disables HTTPS in some way (very unlikely IMO, but not impossible I suppose)
* See id there's a browser setting or something else weird that's made the certs in your browser unavailable. Keep an eye out for the words "Certificate Store" - it's a term that's used a lot in this domain

Note that there will be a lot of certs in your browser: many from sites you connect to, and zero or one that's "yours".
You probably (99%) don't need the details of this, but if you get a confusing list of Certs from your browser and can't make sense of it post the list here.

That zero may matter. In terms of crypto HTTPS sessions are not symmetrical.
The web says that message is due to your browser not recognizing the site's certificate (as opposed to the site refusing to talk to you). That means it's a distinct error for each site (rather than a common crypto (X.509) error in your browser. The odds of every site you tried messing up their own local certs is very close to zero, and the same is true for the certs they've pushed to tour PC.

FWIW here's a real cert (not secret - this is the "public" side of a cert pair) in a readable format.
The last section (between "-----BEGIN CERTIFICATE-----" and " -----END CERTIFICATE-----") is exactly the information as everything that precedes it, but not reformatted for human readability.
It's very unlikely you'll need to figure this junk out, but if you see something like this while debugging you van compare with this to verify it's a cert.

As soon as you get your setup working, I have to suggest deleting said pics or entire thread. All of that data / PNs / SNs / etc. (if this site ever got hacked by ne'er do well types) would definitely be like candy to those such miscreants. Stay safe!

 

[WhitewaterWoman]

Thank you all for the suggestions. Judge’s list got the browsers working again. The problem was I had turned the cpu off for the summer and the dates were off. Once corrected, it worked fine.

Thank you everyone.

 

[JayCee]

Hooray...Congrats on defeating the undefeatable .......
Loving a CPU ,that has lost its mind,can be a challenge🫩

btw, if appropriate to Ask , What brand of Computer/ cpu is it ?
Have been looking for a reccomendation on one of those mini 5 inch square
Computers .? If not appropo, do not worry on answer,or ? send a message ?
TY in advance regardless.

 

[WhitewaterWoman]

It says Intel NUC. That's really all I know. This was purchased some years ago.

 

[Judge]

It says Intel NUC. That's really all I know. This was purchased some years ago.

Intel stopped making the NUC some time back. Handed them over to Asus. Pretty competitive field, though it seems brands like Geekom and Beelink seem to stand out when it comes to "mini pc's".

Thermal issues tend to be of the most concern for the obvious reasons. Small case, smaller cooling. Not something I would recommend for anyone doing much gaming.

GEEKOM A9 Max AI AMD Mini PC | Powered by Ryzen AI 9 HX 370

Beelink | Beelink mini PC-Connect to a wonderful life

The M4 Mac Mini might stand out in this field, though you'd want more storage than the 256GBs the most basic version offers. At least 16GB of memory is now standard with the Mac mini line. Right now a better alternative along with Linux to the floundering Windows 11.

Thank you Whitwater Woman and Judge , much appreciated .
