Remove dust from every computing device. Laptops are famous for collecting lots of dust that is not visible on the outside.
Pets and carpet? You have dust issues in your computer equipment. And don't forget shed human skin.
Use a laptop in bed? You have serious dust issues in your computer equipment. Really, the worst place to use a laptop is in bed.
In my place of employment there is a tile floor, desktops and no pets. Yet, every 6 months I take out servers and desktops and remove dust. And I'm still amazed by the amount of dust being sucked up by these computers. You clean your computers less frequently? You have dust issues in your computer equipment.
Have a non-tech partner that (compulsively) cleans? You have dust issues in your computer equipment.
Any mix of scenarios described here apply to you/your environment? You have serious dust issues in your computer equipment.
Once you eliminate your dust issues, you can look further. Especially older electronics used to be sensitive for changes in environment. I have worked in a company with an electronics lab containing an old 286 computer. If there was a storm front within 10 kilometers of that computer, it would fail. Most reliable weather computer I have ever seen...
Nowadays electronics do not have that many issues with changes in barometric pressure changes, humidity levels and/or temperatures. But it is still possible you have an electronically "worn" unit. When the room temperature goes beyond a certain level, do you turn on AC? There is a chance that this unit drops the power in your house just below a certain threshold that makes your computer environment behave as it does.
There are lots of weird scenarios to think of. But always go for dust elimination first. Electronics attract dust and lots of it. Even if you think you have a very clean environment, do that dust check.
