My computer has started shutting down on its own after about 20 to 30 minutes of use. Previously, it was just losing video output intermittently, and even a slight touch could lead to a black screen, but it never completely shut down. To restart, I had to hold the power button. Now, it completely shuts down unpredictably. This issue isn't due to overheating, as it can happen even when the machine isn't warm. I also suspect that dust might be a factor since my PC isn't very clean, but I'm unsure if that could cause these problems.

Check for old cables or a failing power supply. Also, don't forget about the CPU thermal paste. If it’s dried out, it could cause overheating problems, which might lead to shutdowns.
You should definitely consider cleaning out the dust. Excessive dust buildup can lead to short circuits, which might explain the random shutdowns.
This kind of random shutdown is often related to hardware problems. It could be a loose connection with your GPU or power supply, a failing power supply, or even issues with the motherboard. Dust can definitely contribute to shorts and other issues, so it's something to keep in mind.
Start by looking at your graphics card. It could be the source of the problem.
Have you checked the Windows Event Log yet? It's pretty handy for troubleshooting. You can find error messages related to random shutdowns that might give you some insight into what's happening. Just type 'Event Viewer' in the Start menu and run it as an admin. Then, expand 'Windows Logs' and click on 'System' to see if there are any relevant errors.
