Restarting computer without warning every now and then.

Restarting computer without warning every now and then.

I haven’t encountered a problem yet where a fully infected computer keeps restarting the computer randomly. But the most common problem I’ve encountered where the computer exhibits random restarting is caused by faulty expansion cards like for example network card, video card, sound card, and others. The most common I’ve encountered were caused by either a faulty or malfunctioning video card or a network adapter.

They actually have the same symptom. The computer keeps restarting from time to time. The interval between each restart varies because it happens in random. Sometimes the computer runs for 2 hours without showing any sign of problem and then all of a sudden it will just restart as if you pressed the Reset button on the CPU.

It can easily be fixed especially if the affected device is not built-in to the motherboard because you can easily replace it with a new one. But in case the device is integrated within the motherboard like a built-in video card or network adapter which is very common, there is no solution but to replace the entire motherboard.

Replacing the entire motherboard is required because the problem can’t be fixed by simply installing a replacement card. Like for example if you have a faulty built-in video card and your computer keeps on restarting already, purchasing a new video card and installing it on the CPU won’t fix the problem because the built-in video card is still running even though you are not using it.

I’m not sure if latest editions of motherboards are still like this but this is surely common to older motherboards. One way of checking which device is causing the problem is to remove and reinstall each card one at a time.
