Critical elements identified
The temperatures are symptomatic of very poor cooling even at rest.
Indeed, the minimum recorded temperature (75°C) is abnormally high.
At rest, the temperature should be lower.
All this leads to a drop in the laptop's performance as the processor throttles to avoid overheating.
Here are some tips to improve the situation:
- Check that the laptop's fan(s) are working properly.
- You can elevate the back of the laptop to improve air circulation.
Initially, you can use a book or any object.
If this is effective, you can buy a stand.
No need for an expensive one, no need for one with a fan, the elevation is what matters.
Example stand 1, Example stand 2
- You can also clean the laptop's fans if it hasn't been done in a long time.
Some laptops are more or less easy to open.
Generally, those with a large bottom cover that can be removed are easier to open.
For this, you can watch a tutorial online (search for example "Dell Inspiron 5770 + disassembly" on the internet).
Then open it and remove the fans to clean them. Also clean the air vents.
- If you have the skills, you can also change the thermal paste of the processor.
This can be a bit more complicated than dusting. But if the laptop is a few years old without maintenance, it can help.
If you have doubts, do not hesitate to ask for help from a competent person.
If the problem persists, try resetting your BIOS by following this tutorial.
Problem identified
Please follow this video to fix the problem.
To avoid any issues in the future, it is recommended not to change these settings in msconfig.
Optional considerations
Check from the task manager for software using the processor abnormally.
To do this, open the task manager, then click on the "Processor" column to sort from the highest to the lowest processor usage.
Here is the list of volumes that may lack free space (less than 20GB remaining):
- Storage 2: H: 347 MB free remaining
- Storage 2: I: 182 MB free remaining
It is recommended to leave some free space, especially on the system volume (C:).
This allows for optimal performance and some margin for the system (Windows updates, software updates, etc.).
Here is a video if you want to clean and free up space easily.
Here are the details of the identified bad practices:
Software / tools not recommended :
- The software DriverBooster may seem very convenient at first, allowing you to update the drivers of your computer with just a few clicks.
Unfortunately, it is not uncommon for such tools to offer drivers that are not necessarily suitable for your computer.
This may cause no issues, but sometimes it can create problems (crashes, freezes, blue screens, non-functional Wi-Fi, etc.).
It is recommended to update drivers via the manufacturer's website, as explained in this video.
What to do about these bad practices? :
- If everything is working fine, no worries!
You can simply uninstall the concerned software and/or set a proper power plan if it has been modified.
Just keep in mind for next time that it's not ideal to use such software.
If you still have issues or if you prefer, you can always reinstall Windows properly via this tutorial.

Boot mode >Boot modeBoot mode of the computer:
- Legacy (old mode)
- UEFI (recent mode)UEFI
TPM >TPMThe TPM is a component (physical module on the motherboard or emulated by the processor) that allows secure storage of information.
Specifically, it can store encryption keys, certificates, biometric data, etc.
For example, it is used to encrypt storage with BitLocker or unlock the computer with Windows Hello.
Some anti-cheat software for video games can also use it to confirm the integrity of the game and the system.Active
Secure Boot >Secure BootThis is a security option available in the BIOS.
Secure Boot ensures that the computer boots only with a verified operating system.
This setting may be required by some game anti-cheats (Valorant, FIFA).Active
Boot duration >Boot durationBoot duration is the time elapsed between pressing the power button and the motherboard returning POST OK (successful hardware check).
This can be useful for identifying a slow boot issue.
(long memory training in DDR5, for example).
A boot duration of around ten seconds is normal.
Note that this period occurs before Windows starts.
Applications that launch at Windows startup do not affect this duration.5s

Fast startup >Fast startupWindows Fast startup allows older computers to boot faster.
Sometimes this mode (enabled by default) can be the source of issues such as LEDs staying on, or crashes at startup with incompatible drivers.Inactive
Uptime >UptimeUptime is the time elapsed since the last Windows startup.
This information can be useful to determine how long it has been since Windows was last restarted.
Note that if Fast Startup is enabled in Windows settings, shutting down the computer will actually put it into a hibernation state.
Therefore, Windows only fully shuts down during a restart.
(by clicking on restart and not on shutdown)
As a result, you may sometimes observe high uptimes of several days, even if the computer is regularly shut down and turned on.
However, if Fast Startup is disabled, the computer will fully shut down during shutdown, and the uptime will be reset with each startup.11h 43min
VBS >VBSVirtualization-Based Security (VBS) is a security feature in Windows.
Its purpose is to protect certain parts of Windows by isolating them from the rest. It may be enabled by default on compatible Windows 11 installations.
It can also be activated if core integrity in Windows Defender is enabled, when using WSL2, or other virtual machine-related features.
However, this feature may slightly reduce performance when enabled.
This option only protects against certain complex vulnerabilities. It will not protect you from a cryptocurrency miner or password theft, etc.
Microsoft advises gamers, if they wish, to disable this option. (More information)Active
Antivirus >AntivirusCurrently active antivirus on your computer.
Ideally, it is better to use something like Windows Defender, which is relatively effective and already integrated by default in Windows, or use a third-party antivirus of your choice.
However, it is advisable to avoid less recommended antiviruses like Avast, Norton, McAfee, Iobit, etc., which are known for collecting your personal data rather than protecting you.Windows Defender

PL2 / PL1 >PL2 / PL1Power Limits allow limiting the processor's power consumption to reduce the generated heat.
Example image (anandtech.com)
When these limits are reached, the processor will reduce its frequency to stay within the limit.
The purpose is to allow the processor to operate at a certain power level for a short period, then limit it a few seconds later.
Power Limit 2 (PL2) is the maximum power the processor can consume for a short period (a few tens of seconds).
Power Limit 1 (PL1) is the same but kicks in once the PL2 duration has elapsed.
By default, these are values recommended by the processor manufacturer and chosen by the motherboard manufacturer.
