    Computer freezes/crashes at Windows logo (startup)


    (TL;DR:I have recently been facing random freezes on my computer. It is not OS related as it may freeze before POST or BIOS. I concluded that problem was either overheating or PSU (previously tested RAM with memtest86 and WMD). Installed SpeedFan but it did not help so I uninstalled. After uninstalling, it did not reset my fan speeds and my computer was extremely quiet. I decided to reset BIOS to default settings and it reset my fan speeds, but now Windows is stuck on startup logo. Automatic Repair does not function however safe mode does. Using safe mode, I used "sfc /scannow" and it fixed a couple of problems. However, using "chkdsk C: /f /r" stops at 11% and computer seems to freeze.) Specifications are in the 1st paragraph of the post.

    Hello TenForums members,

    My computer is custom-built from a local retailer. It features an Intel i3 Processor with a CPU fan (model number unknown, as the computer will not boot ) and an ASUS motherboard. There are 2 x 2GB memory sticks on the computer (a total of 4GB). It is currently running Windows 10 Pro (64-bit).
    For more in-depth specs, scroll down to the bottom of this post and click "My System Specs".

    For half a month, I have been facing unpredictable freezes on my computer. I determined that the problem was not OS related, as the computer may freeze before POST or the BIOS logo. I can still consistently hear the PSU, but the fans completely turn off and the computer becomes extremely quiet. I performed a memory diagnostic test (WMD, memtest86, memtest86+) to ensure that my RAM was not faulty. I then researched and concluded on that my computer either had a bad PSU, or was overheating.

    To further crack down the problem, I installed SpeedFan on my computer to address overheating. My temperatures were safe and I did not find any problems (CPU, System, stayed around 30C). I adjusted the fan speed to a low speed to observe if it would crash, but it did not. However, after using low-intensive programs (such as Skype, or Google Chrome with 5 tabs) my computer crashed again. I decided to uninstall SpeedFan and install HWMonitor instead. However, uninstalling SpeedFan did not reset my fan speed. I decided to check the BIOS configuration settings, where I found that that my fan speeds were set to CUSTOM. I reset the BIOS to default settings and restarted the computer.

    Suddenly, the computer crashed at the Windows logo and would not boot into the OS. The computer continuously restarted until I was met with the "Diagnosing PC" text. The computer failed to diagnose my computer, and I left with a "Troubleshooting Problems" menu. I first decided to restore from a system restore point, however this did not resolve the problem. Next, I used "Start-up Settings" to boot into Safe Mode with Networking. This successfully booted me into Windows and my computer was able to function. However, booting normally still crashed the computer. I decided to perform "sfc /scannow" and "chkdsk C: /f /r" in safe mode (Command Prompt with administrator privileges). "sfc /scannow" fixed a few Windows files but did not resolve the issue.

    Currently, "chkdsk" is still scanning the drive. It appears to be stuck at: "Scanning and repairing drive (C): 11% complete" and the computer is fairly quiet. I do not know if it is still scanning or if the computer has froze again.
    Right now, I do not know what the problem is. "chkdsk" has been running for around 3 hours and is still frozen.

    Should I cancel the scan (force restart) and perform "sfc /scannow" multiple times to ensure that "sfc" did not skip any problems? Or should I keep chkdsk on for a couple more hours.
    Any help will be sincerely appreciated.


    Thank you,

    did you do an upgrade and did W10 activate ? if so, then back up any personal files / data and do a clean install of windows 10....it will then activate automatically over the Internet ( been told can be a few days but not tried myself ) maybe this will sort out your issues, if they are OS based issues....
    or can try boot from USB pen with W10 installed using windows media creator....second screen repair then troubleshooting and command line and try one at a time
    bootrec /fixmbr
    bootrec.exe /fixboot
    bootrec.exe /RebuildBcd


    then try repair again or see if it boots from your pc

    Thank you "reddwarf4ever" for the quick reply!
    Yes, I did do a successful upgrade and Windows 10 automatically activated my license (genuine).

    I currently do not want to clean install my computer, as it will wipe all my files.
    However, if it is vital I will clean install. Coincidentally, I partially backed up my computer before the crash, but some files have not been fully backed up.

    I have also tried the "bootrec" commands, (from the W10 "troubleshooting problems" recovery command line) however they have not resolved the problem.

    CHKDSK is still stuck on "Scanning and repairing drive (C): 11%". I am currently decided on whether to shutdown my computer and stop CHKDSK.

    Thank you for your support!

    if you boot from a Linux cd chose the live option so not install, then back up your files and note your programs......sometimes it's easier to start again, so long as you have your data and a list of programs installed.....shouldn't take too long.....when it's stable ( LOL ) maybe you could make a complete HDD image I use acronis true image even has a verify option in options.....I do this to my laptop and PC's.....then when all else fails can just restore the whole lot, can do incremental backups from time to time....good luck

    Thank you "reddwarf4ever",

    It definitely seems that reinstalling Windows is the only viable option here unless anyone else can resolve the problem.
    I may later boot from a Ubuntu or Linux Mint USB drive and copy the files I ned, however I do not want to reinstall now.
    This thread has only been on for 10+ hours, so I'm hoping that it'll get more replies or fixes.
    Please post any ideas/fixes members!

    Thank you,

    Hi guys,
    I decided to download the Windows 10 ISO and make a USB bootable Windows 10 installer.
    I performed the "bootrec" commands however, they did not resolve my issue.
    Then, I used "chkdsk" from the command prompt in the Windows 10 installer instead. (chkdsk E: /f /r) E: is my main drive in the Windows 10 installer.

    CHKDSK successfully checked my hard drive, without stalling at 11%. There were no problems to be fixed.
    I'm still asking for fixes/ideas.

    Thank you,

    Hi TenForums Members!
    Sorry for the super late reply, however I have fixed the issue with my computer!

    As I stated earlier on my first post, after I reset my motherboard my computer was not able to boot up.
    However, I checked my motherboard settings earlier today and found an option called "No-execute" memory.
    I recalled that it had been enabled before, so I decided to enable it.

    My computer then successfully booted right into Windows, with no files lost (some new applications were lost due to my trial with System Restore).
    I am very happy with my solution, and recommend anyone with booting up problems in Windows 8/10 to make sure that NX Memory (in BIOS) is turned on. It is a requirement of Windows 8/10.

    The computer still randomly freezes, which I suspect to be the HDD as the drive has been producing "ticking" noises.
    I will definitely diagnose my HDD for any problems.

    Thank you for all your support!
