The cause of computer overheating and shutdown is different from case to case, but what happens when a computer runs hot excessively is always a hot issue. If your computer’s CPU starts to overheat immediately or you play games, you hear an alarm sound that informs you that your PC is running hot. This could be a temporary issue or a more serious issue based on the design and signs.

In the article, we’ll concentrate on one aspect which is: what happens when a CPU is overheated as well as what can be the signs when the PC is overheated.

What Happens When a CPU Overheats?

What Happens When a CPU Overheats

The results of overheating are dependent on the style of the. Usually, when a CPU of the computer is overheated first, it will show:

  • The computer may either freeze, hang or even crash.
  • If your prologues are overheated, you’ll be confronted with a blue screen that says “death” (BSOD) warning.
  • A few PC users are faced with an abrupt shutdown or automatic restart.
  • If your device has an alarm for overheating it will start to blast.
  • It is also possible to see pixels or other graphic artifacts that appear in the display.
  • The constant heat generated by CPUs can harm motherboards.
  • Overheating also can affect some of the slots on the motherboard like the motherboard‘s VRM.

If you are constantly running demanding tasks on a computer that is overheated, it may reduce the lifespan of the CPU. In extreme cases, you will feel the CPU is burning, and it’ll start releasing smoke. If you ignore the issue of overheating the CPU fix, there are possibilities that the CPU is melting the motherboard completely. All of the mentioned signs don’t need to occur simultaneously. The scenario is dependent on the hardware of your computer.

Why Computer CPU Overheating in BIOS Occurs?

There are many reasons that are why the CPU is overheated immediately. The issue could arise as a result of malfunctioning hardware or faulty software for monitoring temperature. If users don’t give the CPU enough space to breathe in the fresh air, the CPU can overheat. You must seriously consider investing in the top CPU cooler as there could be dust and other debris inside which block the ability of fresh air to flow in. It is important to be sure to clean your computer to stop your computer from overheating.

What To Do When Computer Overheats For Too Long

If you’re experiencing frequent CPU problems, then you must adhere to these tips for DIY to stop your computer from overheating.

Clean up dust first using the help of an air purifier.

  • You can run your computer using the case open. (Check Gaming PC Cases)
  • Set your computer far from the wall to ensure airflow.
  • Avoid hot neighbors.
  • Finally, you should improve your cooling system using liquid or air.
  • Set the fan speed manually so that it is running at an ideal RPM.
  • Can Overheating CPU Damage Motherboard.
  • It is not a cause for concern if you overheat the motherboard. It is more often a problem that reduces the lifespan of the CPU. Also, the PC becomes hotter and hotter, it will switch off.
  • However, on the power draw aspect, the motherboard’s VRMs could not cope with the power draw and may burn out and reduce the life of the motherboard.

In Extreme Cases

  • Heating can cause damage to the VRM on the motherboard. The CPU may not be able to write on top of other instability issues based on the severity of the damage.
  • The capacitors may explode and render the motherboard inoperable.
  • The circuitry can also be damaged by overheating that is connected to PCIe lanes or CPU RAM, etc.
  • All of these could make a specific slot or piece of hardware to be incapable of communicating with the chipset or the system leading to instability, even complete non-booting.


If your computer is overheated, you may experience instability issues, thermal throttling and there’s also the possibility of the CPU becoming lit. The latter is uncommon, so you need not fret about it, particularly when you keep your PC clean. Overheating-related stability issues can be stressful since you may lose a file that you’ve spent a lot of time working on or lose progress in the course of playing. So, fixing your overheating problem is essential. The majority of the time it’s simple and inexpensive to fix Don’t fret about it too much.


Do CPU overheating cause an inability to perform?

The CPU is overheating and is causing the CPU to operate at a lower speed and a lower CPU utilization and this is why you get low FPS when playing games. It doesn’t matter whether you alter any settings since your CPU isn’t operating at its maximum speed.

Why my laptop is hot, even when it’s off?

The possible causes are dust blocking intake grilles and exhaust ports. Other reasons include a block in the fan or the degeneration of thermal paste.

What is the reason my processor getting overheated so quickly?

There are several common reasons that your computer could overheat. The first one is when damaged or misbehaving components produce higher temperatures than they need to. Another reason is that the cooling system designed to prevent overheating from occurring – whether you’re using air- or liquid-cooled unit, isn’t doing its job.

Do excessive use of thermal paste cause damage to the CPU?

Applying too much paste to the socket will generally not affect performance due to the act of tightening the cooler eliminating the excess. A lack of paste isn’t a good idea however anything that is above the threshold of the minimum will cause the same effect after the cooler has been tightened.

Is thermal paste that has dried harmful?

The paste carries heat more efficiently than air however it’s far from the same quality as metal. When it is dried it may become crumbly (leaving the air pockets) which means that the gaps don’t fill equally. The liquid may also assist in transferring heat.

Can overheat damaged laptop?

As per the website of Houston Chronicle laptops and other electronic gadgets can be seriously damaged by excessive heat. The host processor may make a computer slower and make it work less efficiently. An overheated battery could reduce its battery lifespan or make it inoperable.

Is it okay for laptops to become hot?

Contrary to your initial instincts the fact that your laptop is hot isn’t necessarily an indication of major issues. Normal computers will get hot during use, but the majority of laptops operate well in temperatures ranging from 100-95 degrees.

Does Gaming laptops get too hot?

Gaming laptops can get extremely hot due to their powerful processing units and graphics card that create plenty of heat under stress. … Overheating results in thermal throttling which causes an increase in gaming performance. Extremely high temperatures are an important cause of hardware failure that is premature.
