Many gamers know how important it is to clean their gaming rig from time to time. Otherwise, it can turn into a health risk in the worst case. A user perfectly demonstrates with his computer why regular maintenance is important.
What kind of computer is it? The user “GPU-Collector” reports in his Reddit post from March 24, 2026, that a friend asked him for help with his PC. The computer was said to not be starting anymore.
The builder agreed and received a nasty surprise upon opening. The removed motherboard and the entire CPU cooler were covered with a thick layer of various-colored dirt.
It is also important to take special care of your components during the current RAM crisis, as a replacement is not always possible. A summary of the rising prices is given in the following video:
Why is the condition of the PC so bad? According to the builder, the computer was not only extremely dirty on the outside, but it was also said to have smelled like a mixture of cat urine and dust.
Later, the Redditor shares a picture of the functioning, cleaned motherboard in a comment on the original post. However, the appearance of the horror computer’s case is not mentioned in the post. Nevertheless, the dirty motherboard was already dangerous without a case.
But even gamers without pets can accumulate a lot of dust over time. Another user, for example, shows what his rig looks like after 8 years of operation.
Dirt can be treacherous
Why does the computer pose a risk? Apart from the unpleasant sight and smell, there are several potential sources of problems when operating such a device:
- Performance can be massively affected because, among other things, the CPU cooler was coated with a thick layer of dust and thus was less able to dissipate heat. In serious cases, such contamination can also lead to a failure (according to Corsair).
- Dust is easily flammable and can quickly become a fire risk, which not only causes damage to the hardware but can also spread beyond the computer (via YouTube).
- Accumulations of dirt and animal excrement can present a health risk in the form of skin irritations, respiratory problems, and dizziness, especially if a person is exposed to them for an extended period (according to rug-rehab).
Therefore, it is important to clean a computer regularly to prevent such risks.
How do I quickly and easily clean my computer? There are many ways to clean your hardware, and therefore we have put together some tips for you:
- Important: Always disconnect your devices from the power supply first and discharge yourself by using an anti-static wrist strap during cleaning. Otherwise, an electric charge can damage your components.
- Blow dust out of your PC using a weak air duster, for example. However, do not use a vacuum cleaner, as the strong airflow can damage important parts. We also recommend not dusting your computer inside your own four walls, as this only unnecessarily spreads the dirt.
- For dirty surfaces, use a microfiber cloth and a small amount of isopropanol. This evaporates quickly and leaves no residue. However, wear gloves and ensure that your skin does not come into contact with the alcohol.
For most users, it is often sufficient to clean their computer every few months or only once a year. What matters is that it is not completely forgotten and that the device does not mutate into a potential risk. It is also not the first time that a Redditor has complained about dirty hardware: User complains about a dirty PC he needs to clean – Shows with a picture how harmful smoking is to your hardware
