I've been using ChatGPT as a tech support for months — here's what I learned
I began having issues with my new computer late in the one-year warranty cycle. My computer would experience unexpected crashes whenever I loaded up games, programs, Chrome or Firefox tabs, and Discord.
At first, I chalked it up to GPU driver issues, since I downloaded a new Nvidia GeForce Game Ready driver that caused conflicts with overlays.
I also asked others for advice, and most said it was a RAM problem. But I didn't understand how it could be, given that I have 32GB of internal RAM plus my GPU's VRAM, and it wasn't malfunctioning at the start.
But I knew something was wrong when sometimes all I ever did was open three Chrome tabs, and it would crash within an hour of browsing.
I realized that the more I tried to find answers, the more lost I felt. I needed to know whether it was faulty hardware or a software issue. That's when I began seeking advice from ChatGPT as a tech support companion.
ChatGPT can be accessed from the web or via an app on any device, including your Android tablet.
I used ChatGPT to guide me through logical diagnostic steps
Even as a trained LLM, it is never going to be perfect
When it comes to Windows 11, I find it more confusing and overwhelming than Windows 10. As a result, my firewall is overly aggressive, and many programs I try to install are blocked by default.
I know this because rolling back my Nvidia GPU driver turned out to be complicated, since the installer kept failing even with administrative privileges enabled.
Eventually, I realized I needed structure. Instead of panicking and trying to figure out the problem on my own, I went to ChatGPT for help.
At first, I was just using ChatGPT to analyze my crash logs and dumps, to help me parse the technical details and get a clue about what was happening. But it wasn't perfect.
My crashes worsened in December and January, and I was accumulating more crash logs than I had with my attempts. I also didn't want to use different accounts to have ChatGPT analyze my logs. This is because of ChatGPT's memory feature.
Since I've been using ChatGPT for months, the chatbot can recall details from my chat history, including context about previous issues and my hardware specs.
The more context I fed ChatGPT, the more concise my sessions became. Diagnostic tools and steps were becoming more targeted to my current problems.
For example, my computer is pre-built, and some of my BIOS settings are locked because of the OEM. I wasn't able to turn off my XMP profile to check my RAM.
Instead, I ran MemTest as ChatGPT recommended. My results came out clean.
We moved on quickly from my PC's RAM to my GPU drivers. Many applications will use your GPU (hardware acceleration). Nvidia had some issues in their recent driver updates, particularly around 576.88 and 591.86.
I ended up uninstalling the Nvidia app, then I had ChatGPT walk me through using DDU to perform a clean uninstall of my current drivers so I could roll back to a more stable Game Ready driver.
After some testing, the chatbot and I concluded it wasn't a driver problem. So we looked at hardware tests. I downloaded OCCT but found that the guide provided by ChatGPT was outdated.
That's when I began using the new public model more effectively. The GPT-5 series lets me upload images for analysis. I had ChatGPT generate settings that fit the context of the new OCCT UI I screenshotted in the chat.
The only major downside was that reaching my daily limit forced me to either start a new chat or wait for the cooldown.
If you didn't paste images in the chat like that, you could use an older model to keep conversing with the chatbot.
So even though sending screenshots helped me immensely, I had to wait until the next day to use the same chat.
But to me, the wait was worth it because I didn't want to overclock my PC unnecessarily. I just needed to run standard checks to see if my GPU was operating as it should.
My GPU failed the test instantly, and I reported those results. However, this is when I started to reach limits with the chatbot.
The chatbot thought my GPU might need replacing, but turns out there was one big factor ChatGPT missed: my PSU.
ChatGPT was a great help, but it has limits
It pushed me to learn more on my own
One thing I noticed was that ChatGPT acted very certain that they'd found the cause or root of the problem.
The language would be similar to "I am 90% sure that this is your issue," and I'd feel less anxious about that type of reassurance.
But in truth, I kept cycling back to RAM and GPU hardware problems, even though my gut told me to revisit the PSU problem.
Mainly because it was rare for my computer to restart or turn black, but it had happened. Since PSU crashes (black screen, computer restarts) were less common than my application crashes, ChatGPT didn't consider PSU a probable cause.
I finally investigated more on my own. It turns out that I definitely have a PSU problem.
My PC came with a 500W power supply, which, at the time, I assumed would be at least 600W. But running a 14th-gen Intel 7 processor and an Nvidia RTX 4070 is a power-hungry combination.
I really need a 750W PSU to operate comfortably. I fed this information to ChatGPT, and its certainty tone came back again, pushing the chatbot's previous assessment further down the list.
Though ChatGPT recommended commercial PSUs, I still needed to do research.
Turns out that I can't buy a commercial one. The PSU I have has a custom configuration for pins with my motherboard.
It would have been detrimental if I bought one of the recommended ones and then changed it without checking.
The take-home lesson is that, no matter how confident ChatGPT sounds, don't take what it says as fact. Verify every suggestion and keep asking ChatGPT questions if you're unsure.
At each step, I'd contact my friends who were more tech-savvy than I was with hardware, and I'd use that info in my future ChatGPT conversations.
Eventually, I was able to get ChatGPT back on track.
ChatGPT may have its flaws, but it was still productive
I still came out feeling happy with my experience. I spent months learning new concepts.
ChatGPT taught me more about my computer's internal components. It also taught me how to properly understand and read my Event Viewer.
Plus, more importantly, it gave me direction when I needed it most. Even if I didn't always agree with ChatGPT's assessments, it still steered me in the right direction when conducting my own research.
As a supportive tool, I came out happy with what the chatbot offered. I wouldn't use it as a primary tool for building a PC, for example.
But overall, I am more than happy to use ChatGPT again in a similar context; it was still a big help, a bigger help compared to Google Gemini.
