Apps and browsers closes without error

Question

Apps and browsers closes without error

Onur Sengul 0

Have a nice day,

My anti-virus stopped working and froze (Kaspersky), uninstalled, and tried to reinstall, but cannot; it says something about Windows files not working properly.

Actually, I am tired of it, and it started like 2 months ago. Every browser I tried (Chrome, Firefox, Edge, Opera) closes without giving any error. Randomly. Sometimes every 5 minutes, or after 3 hours.

It also happens with Windows products (Teams, Office, etc.); sometimes they work properly, then later start to shut themselves down again, without any error in the middle of nowhere.

Games are the same; they just close. No error. After 5 minutes, sometimes after 3 hours, no problem.

It is all random. As the operating system wishes.

Updating every driver, uninstalling, etc., does not solve anything.

Help will be appreciated.

Hi Onur Sengul,
Welcome to Microsoft Q&A forum. I'm happy to help.

You probably have memory problems.

To diagnose the problem, try the following suggestions:

Go to BIOS and disable any overclocking and XMP
Check memory with a tool like Memtest or Memtest86

Use a third-party tool like Memtest or Memtest86 for memory testing. It is recommended to run memory tests in DDOS or standalone environments and run them for at least 3-4 cycles to ensure that memory is fully tested.
- If the memory test returns any errors, there may be a problem with the CPU memory chipset, overclocking configuration, or the memory hardware itself.

Your Windows 11 installation seems to be very corrupt.

Open the Settings App.

Go to System - Recovery.

Click the 'Reinstall Now' button in the 'Fix problems with Windows Updates' section, then wait for that process to complete, this process should resolve any corruption in WIndows and will not affect your files, settings or installed apps.

Thanks, Dave, for your time to answer. Sorry for the late reply.

"Reinstall now" button is greyed out, and I cannot press it. Today I do not have problems for a couple of hours, but now it has gone crazy again. Who knows what will happen 1 hour later :)

Any further help is appreciated

Thanks

If that process is not available to you, then the best option is to perform an in-place repair with the Windows 11 ISO.

Please ensure you download the ISO in the same language as you use for the Windows UI, follow the steps, this is then not like re-installing Windows, it is just like an update and your personal files, settings and installed software will not be affected.

Click this link:

https://www.microsoft.com/software-download/windows11

to download the Windows 11 ISO

When the ISO file completes downloading

Disconnect from the Internet

Disconnect all external devices with the exception of a mouse or keyboard.

Temporarily disable any 3rd party Anti-virus you may have installed

Then, in Windows File Explorer, double click the ISO and then run Setup.exe and select the Install option.

Very Important - ensure you select the option to keep your files and apps.

Thanks again, Dave.

No, cannot, not as ISO or to a USB drive from the offical web site :) This is crazy.

Cannot even download it :)

Throw away the computer?

In that case, the only option may be to reset Windows while keeping your files.

Click the power button on your Start menu.

Press the Shift Key and click Restart

Your PC will boot into the Windows Recovery Environment

Go to Troubleshoot - Advanced Options - Reset this PC

Choose to keep your files and apps, just your files or to keep nothing

Then start the Reset

Tried.

1.) Reset my PC. Keeping files. Downloaded from the cloud. Reinstalled. Around %78 installation crashed.

2.) Reset my PC. Just format and erase everything. Done. Have a clean copy now.But still cannot download 11 to HDD ISO or to USB flash. Same error.

So if it is a hardware problem, like SDD/HDD or RAM i am glad to change it. Ok.

But cannot get a copy of registered Windows 11 in my hand, not even in a clear, formatted version, not even as iso or USB still. In offical way?

So if I buy a new HDD/SDD how will I install it in an empty HDD? Cannot even download it because of errors? I do not get it. I have nothing in my hand :)

Thanks, Dave.

If the Windows Reset did not resolve the problem, then the best option is to backup your files, create a bootable Windows USB on an empty 8GB USb flash drive, which you may need to create on another working PC and use that to clean install WIndows, if you get any error or disk problems during the installation, then, there may be a problem with your drive.

Click this link: https://www.microsoft.com/software-download/windows11

to download the Media Creation Tool (Click on Download Tool Now), with that you can create a bootable USB flash drive (min 8GB) using that tool.

Then, Boot your PC from the Installation Media you just created to begin installing Windows 11.

During the installation process skip the steps which ask for a product key and select the option 'I am Reinstalling Windows 11 on this PC'.

It sounds like you're experiencing significant instability with your Windows system, which can be caused by various factors including corrupted system files, issues with drivers, or even malware. Here are some steps you can take to troubleshoot and potentially resolve the issues:

Run System File Checker (SFC): This tool scans for and restores corrupt Windows system files. You can run it by opening Command Prompt as an administrator and typing sfc /scannow.
Check for Malware: Since your antivirus is malfunctioning, consider using Windows Defender or another trusted malware removal tool to scan your system for infections.
Perform a Clean Boot: This can help identify if background services or startup programs are causing the issues. You can do this by typing msconfig in the Run dialog, selecting "Selective startup," and disabling all startup items.
Update Windows: Ensure that your Windows is fully updated, as updates can fix bugs and improve system stability.
Check Event Viewer: Look for any critical errors in the Event Viewer that might provide more information about what is causing the applications to close unexpectedly.
In-place Upgrade: If the issues persist, consider performing an in-place upgrade using the Windows 11 ISO. This can repair your system without losing personal files.

If these steps do not resolve the issue, it may be worth contacting Microsoft support for further assistance, as they can provide more tailored troubleshooting based on your specific situation.
