Your New PC Freezes Randomly? Here’s How To Fix It

You’re not lucky after all, are you? You got a new PC or built one yourself because you’ve had enough of your old one or you just wanted to upgrade it to keep up with the modern games or for whatever reason you had in mind, a regular computer can freeze up for a lot of reasons but don’t worry I’m not going to go through all of them because it won’t make sense, for example, a computer virus is not a possible reason because it’s still a new PC.

Compatibility issues

Some folks on different forums suggest that this awkward happens because of compatibility issues, try updating the BIOS version once you finish building your new PC, other compatibility issues may happen due to other parts like the CPU or RAM being not compatible with the motherboard.

I hope you’ve read a guide before building your computer, there are a lot of factors to keep in mind before buying the new components.


Overheating is another common reason for problems like this one, if your new computer doesn’t get enough cooling it’ll start to freeze up and the CPU fan will spin quickly and maybe you’ll start to hear some noise as well.

You may start experiencing this issue when you run heavy games or demanding programs, a good tip to use is to monitor the temperature of both the CPU and GPU once you open your computer and when running demanding programs.

You can use this simple software to help you monitor the temperature:


Someone mentioned this awesome software while I was doing research for this post, its duty is simply testing your computer components by putting it under pressure or stress to ensure its endurance, reliability, and stability

Inadequate PSU

Can the PSU cause your computer to freeze? Yes, definitely, when your computer components don’t get enough power they don’t work properly or at least the way they should be, this will eventually cause your computer to freeze or worse damage your computer parts.

A good practice would be to choose a really good PSU that can provide all the parts with sufficient power, go for a reputable brand like EVGA, Corsair or Seasonic.

Another good precaution is to get a protective unit to ensure that your computer still works fine even when the electricity goes off (for a short time of course).

There are some calculators online that can help you get an estimated number of the expected power your computer is going to consume.

You need more RAM

A lack of RAM is another common reason for this problem, it’s a beginner mistake, OK I’m not trying to offend you in any way but it’s the truth, every game or software has minimum requirements in order to operate or run properly, if you have let’s say 2GB of RAM in 2019 (as if the date of writing this post) is not enough to run modern programs or games, you need to upgrade it as soon as possible.


This one is for gamers, all gamers seek the best performance thus they attempt to overclock the CPU but sometimes the computer becomes unstable because of an improper overclocking process, the most obvious reason is the lack of voltage, when you overclock your CPU it’ll consume more voltage in order to give the required performance or speed.

After overclocking the CPU you need to stress test your computer using a software like Prime95 if it freezes then you need to increase the voltage a bit and rerun the test until it becomes stable.


As a last tip, I can think of is to take it back to the manufacturer or the store you got it from, it should still be under warranty I suppose.
