(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 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.
