May 6, 2025 – Kids…

May 6, 2025 /

“I don’t know what happened, it just stopped working”. Huh, I have no idea. I guess that I will take a look and see if I can see anything. Oh, I see there is a bunch of sand in here that does not belong.

In years past, I have replaced a few RAM DIMMs, hard drives, disk drives, and the like. That doesn’t make me and expert in PC repair, it makes me a part swapper that has a little knowledge of what things are inside of the cover. Years ago, the motherboard would sometimes have some diagnostic LEDs as well as speaker beeps. The combination of those two tools would help steer you in the right direction.

I haven’t seen this problem in years but every so often, the motherboard battery would die and the PC would act like a failed hard drive. It seems like those batteries never die today, at least I haven’t dealt with it in my batch of ancient PCs. Once again, the onboard diagnostics were very helpful in resolving quickly.

When my son said that his computer makes a constant crackling noise and doesn’t stay connected to Wi-Fi, my first thought was that he dropped the thing and there was a loose connection. Dropping electronics is a very common occurrence that never happens with kids either.

Where to start with these things? I just turned it on. I noticed that there were a lot of updates that needed to be applied. That got me thinking about drivers. Sometimes not having the right driver installed can even have wildly erratic behavior. I didn’t see any driver updates that needed to be made. That did not make any sense.

First, this PC had not been on my network since before I made all of the upgrades in March. The location of his room was notoriously spotty because I fought with doorbell many times and his room is directly above that. I signed the computer into the network with new credentials and things seemed pretty stable. I think the Wi-Fi stability was just a phantom problem of a weak network signal.

Now to the crackling noise. It sounded like a static-y AM radio station at times. Although my son said it was happening constantly, I only heard it about five times in fifteen minutes for a couple of seconds. He said that it was much improved. I figured I would just let all the updates install and see what happened from there.

Meanwhile, I did some research into the internet. It seems like this problem is not unique. In all of my years as IT manager, I have never heard of it. Despite all of the claims of high dollar sound cards and meticulous checking of connections and power, most of the claims were resolved by disabling sound components in device management. I still think I need to get under the covers of this machine. I was still under the impression that it might have been dropped and has loose speaker connections.

When I took the back cover off, viola. Sand contains conductive material and at the very least, it doesn’t belong inside of a computer case. I took the compressed air to the motherboard and speakers and everywhere I can reach to blow it out. In hindsight, I think a vacuum is probably the best first approach because blowing the sand around risks jamming the particles deeper in the machine. When I turned it on, the crackling was gone.

End Your Programming Routine: When approaching a problem that is new or unusual, the first step is to take a look. Whether it is automobiles or CBs, it is amazing what the human can recognize as ‘not quite right’ even if you do not know how to fix the problem. In this case anybody other than a blind person should be able to recognize that sand doesn’t belong in a computer. In the future, I will be more insistent on making sure that my son performs basic troubleshooting steps before I get involved. This is how we combat a culture of ‘call a guy’ from completely taking over.

February 25, 2025 – Who Doesn’t Want This?

February 25, 2025 /

Towards the end of last year, things were humming along on my techno junk front. Last year, I completed my surround sound project. I purchased a couple of scanners, I bought a home base radio. The next thing I was going to focus on was an antenna. All of a sudden I realized that I needed to refocus my resources on my hike or I was going to run out of time. Hence the New Year, New Gear series that I have been running.

Despite my focus on my hike, I still check Craigslist every couple of days just to see if there are any deals out there. My criteria for deals are not just cheap but also close. I will use eBay for used things. There is plenty of old, out of date or out of fashion or just plain used there.

Sometimes, I see inexpensive items on Craigslist. When I was looking for subwoofers, I probably looked for over a year. While I waffled whether I really wanted one or not, the thought of coordinating a meetup and driving over an hour was not really a deal for me. This was especially true when I could pay the same amount on eBay and have it shipped. After looking for a year, what is another week or two.

By that same token, I saw some speakers for sale locally. They were $30 and in town. I had been thinking that I would like to have an extra set of speakers so I wouldn’t have to tear my setup apart when my wife want’s to have a birthday party or karaoke. That is what I consider a deal. Technically, I didn’t need it. I didn’t necessarily want it either but it was hard to refuse. Incidentally, I haven’t used them at all in the three years since I bought them.

What I find on Craigslist is a lot of the same things for a long time. A lot of it is nearly useless items like old electronic vacuum tubes or things that I have no interest in like a 10 year old Kindle or something like that. Every once in a while I see something that I have see more of, that is today. What the heck is a paranormal kit?

When you read the description, the seller is now into baseball cards, not chasing ghosts… what? Clearly this is an individual that falls hard into their hobbies, but what niche ones they are. I grew up in the golden age of baseball cards. That would be the late 1980s. I learned recently that the exclusivity that Topps had, expired. As a result, new companies like Donruss and Upper Deck all of the sudden appeared. This caused the value of cards of all era cards to become very popular somewhat lucrative. Something like a Don Mattingly rookie card was worth $20 at the time. But, once the gold rush became industrial extraction, the market never saw the extreme highs of the time again.

Back to relevant business. I wouldn’t say that I don’t believe in ghosts but I am skeptical. I am open to the idea but I have also never felt or seen something to make me believe otherwise. Part of me would like to think it isn’t that much money to perform some experiments. I mean, who wouldn’t want to have a device called “Ghost Detector”? Can you imagine the Halloween parties that you could throw?

The point being, sometimes I run across interesting things. When that happens, I look at the extra pictures and my mind starts to wander about who is this person? What would cause them to fall so deep in a rabbit hole? Would I allow myself to get in such position? Regardless of the thing that they are into, I find it fascinating.

End Your Programming Routine: My techno junk fascination will continue to march on at some point in the future. I was thinking back to this time last year and it was all about prepping to work away from home or at least my office. That was several months of my incidental spending money but it was also for the stage in my life. I was buying portable monitors and do dads for productivity. This too will pass and then it will be back to where I left off. Tell that to my shooting and reloading pantry as well.

May 4, 2020 – The continued legacy of ‘Techno-junk’

May 4, 2020 /

I had another occasion to dig up what I call Techno-junk this weekend. It happens to be an old desktop computer from the Windows XP era. There is a circuitous route for why I wanted it in a minute.

I am having a problem with the headlights on our 2010 Navigator. They will just shut off without warning. Sometimes it is one side, other times it is the other side and sometimes it is both. When driving in town, you may not notice that your headlights are out, everything seems dim however. So, I wanted to use my scanner to check for any codes that might be present.

I didnt get any codes at all. My scanner is only configurable to the model year 2007. This scanner is upgradeable, by connecting it to the computer via serial cable otherwise known as COM. This is an old connection style, today it would USB. In fact, there are COM to USB converters, but I do not have one.

This machine we used three generations of operating systems ago. I think we probably used it from around 2005 – 2012. It does have a COM port and I have connected this scanner before. This computer has kind of lagged around, not for this reason but because it has personal information on it, including a lot of old photos. I have made efforts to remove these items but the total status remains unclear.

The first problem I had was that the BIOS battery was dead. Apparently, I knew this because a new battery was installed, but the protective sticker was still on the back of the battery. I installed the battery and set the BIOS clock. Then the cover was off, and there is some sort of proximity switch that prevents boot up without the cover.

I did get the computer running, I navigated through all of the errors and warnings to update the scanner. Then I started looking around to see what was still on this computer. I found a lot of music, iTunes worked perfectly and it notified me that the newest version was available for download. It even downloaded current versions of podcasts that I am still subscribed to.

When I launched Rhapsody, it blue screened. After reboot, it launched but it was a program that wasn’t used much so it really didn’t have a lot of data or function. While I was messing around, updates were prompted to install.

Twenty-eight updates were attempted to install. At least six failed, they were .NET framework service packs and things of that ilk. But I was sure surprised that there were any updates. I had several blue screens during the process so I am not sure what the real problem is. Now, the machine wont boot passed the BIOS check.

There are some warning lights on the back of the case. The status indication is that there is an ‘other problem’. Troubleshooting steps are to verify the connections of the hard drive and disk drive are solid. It kind of acts like a hard drive failure though.

One trick that I have used in the past is to remove the hard drive and plug it into a working machine. That bypasses all of the other hardware issues. If I can offload the data (one more time), this machine will finally be headed to the scrap heap.

Because my scanner is OBD II specific, there are no other updates that it will receive and the COM port will no longer be necessary as that protocol was ended in 2012. The scanner is as up to date as it will ever be. Some things will be lost forever like music downloaded with the Windows Music license format. That idea was not carried forward and will only play on devices originally downloaded. Tax years 2011 and 2010 are no longer relevant. Only photos are the prize.

I guess what inspired this post was my amazement that six years after support ended, I still had pending updates. I know that this machine has been on and connected in that time. This experience has driven a few planned posts as well 1) headlight resolution of the Navigator 2) repair of the Yamaha sound systems – I know what is wrong there.

I am still very much busy with my housing project. That is partially why last week was so barren. But I will be back.
