Here are the steps you can take to address the user's complaint and figure out if the system is hanging because it may be too hot:

Step $1$: Make Sure Overclocking

This is what you need to do to see if the system has been overclocked:

Start up the computer again and go into the BIOS$/$UEFI setup to get to it$.$ Most of the time, this is done by pressing a certain key $($like Del, F$2,$ F$10,$ etc.$)$ right after turning on the computer. During startup, the screen will usually show you the key to enter BIOS$/$UEFI setup.

Check the CPU Settings: In the BIOS or UEFI setup, look for the CPU settings or a section that talks about overclocking. This is where you can find out what the current CPU clock speed is and whether it's set to the default settings or has been overclocked.

Compare to Default Settings: Make sure the CPU clock speed is the same as what the manufacturer recommends as the default setting. It is certain that the system has been overclocked if the settings are higher than the default.

Step $2$: Make sure it's not too hot.

To be sure that the system isn't hanging because it's too hot, do these checks:

Boot and Check Temperatures: When you turn on the system, you can immediately use a tool to check the temperature. You can do this with a number of software tools, such as HWMonitor, Core Temp, or SpeedFan. These tools show the temperatures of important parts like the CPU and GPU in real time.

Keep an eye on temperature changes: Write down the temperatures as soon as the system starts up$,$ and then keep a close eye on them as it works. Right after the system freezes, check the temperatures again.

Step $3$: Fix problems with overheating

If it turns out that overheating is the problem, here are four things you can do to fix it:

Clean Up Dust and Debris: Over time, dust can build up on parts and inside the computer case, blocking airflow and making the computer overheat. The computer's fans, heatsinks, and vents should be cleaned inside and out.

Better Cooling: Think about improving your cooling options. This could mean adding more fans, getting CPU or GPU coolers that work better, or making the case's air flow better.

Check the Thermal Paste: Make sure that the thermal paste between the CPU and GPU and their heatsinks is properly applied and hasn't dried out. If you need to$,$ replace the thermal paste.

Check and Change Fan Speeds: To check and change fan speeds, use software tools or the BIOS$/$UEFI settings. Increasing the speed of the fans can sometimes help get rid of heat more efficiently.
