Hello BC forums,
Earlier today I posted my issue on reddit. You may read through it if you need any extra insight about the bullet points I'm about to paste (latest findings). Or simply ask and I'll do my best to answer. I'm hoping there will be input from more than one helpful soul on the net.
My system specs (missing WD HDDs, 840 Pro SSD and AX760 PSU). Also detailed on the reddit post.
All the components are new except for the HDDs, the 840 Pro SSD which I installed a fresh copy of Windows 10 on, and the GTX 670 GPU. These components appear to be perfectly fine despite originating from my last PC that had a faulty PSU which eventually fried one of my GPUs (in SLI) and my other SSD that Windows used to be installed upon.
Freezing at idle when in Windows 10. Sometimes when doing something trivial, such as opening Edge browser or clicking on a Removable Drive in File Explorer. System hangs and CPU fan goes to maximum by the sounds of it. Requires a forced power-down via power button. After this hang and power-down, booting the system sometimes hangs at the POST stage: the board's onboard LEDs (Q LEDs) to detect DRAM, CPU, VGA and booting device problems show a constant green light on the Boot LED. Requires another reboot to get past the POST stage into the OS.
Believed to be not at fault:
GPU - Swapped current GTX 670 GPU for old GTX 260 test GPU, booted into OS. Still freezes.
- Connected to Corsair AX760 PSU via single cable with 2 x 6+2 pin connectors.
RAM - Ran 2/4 passes (1:40 hrs) on latest free Memtest86, 0 errors.
- Booted into OS twice with 1 RAM stick each boot. Still feezes.
SSD - Unplugged all SSDs, booted into OS. Only OS drive connected (SSD). Still freezes.
HDD - Unplugged all HDDs, booted into OS. Only OS drive connected (SSD). Still freezes.
DISK - All disks have no errors according to SMART diagnostics.
USB - Unplugged all USBs, booted into OS. Only keyboard and mouse connected. Still freezes.
Possibly the culprit:
CPU - Idle temps in BIOS read 50 degrees Celsius.
- Idle temps in BIOS (with case side panel off) read 48.
- Idle temps in Windows using a diagnostic tool reads 38.
- Downloading a game via Battle Net game client, temps read 60.
- Heatsink was installed in one go: placed on CPU, then AMD Prism heatsink's clips secured.
- Stress tested with Prime95 Small FFT for 3 minutes without a freeze. Temps read 85. System remained stable for 40 minutes of idle until I decided to resume downloading of a game. Froze within a couple minutes. I would test for longer, but I don't see how I could tell if the freeze was due to Prime95 or whatever is causing the freeze.
PSU - New PSU. No apparent issues. Don't own any tools to test it with.
MOBO - Asus ROG Strix X470-F was flashed to the latest firmware upon arrival (v4011).
- Settings at default: used "Load Optimized Defaults".
- No manual settings set except time and date. No overclocks, nothing.
OS - Fresh Windows 10 N Pro 64-bit v1803 install onto Samsung 840 Pro. Done via bootable USB. Required manual formatting of disk via diskpart, and converting from MBT to GPT before Windows 10 installer would allow Windows to be installed (since motherboard is UEFI) to the desired partition.
- Some software intalled: Battle Net client, Steam, Discord, KeePass, Firefox, VS Code and Eset Security.
- My Windows 10 serial key has been blocked. I extracted it once upon a time using a Nirsoft program as my system was one that was upgraded from Windows 8 Pro N to 10 for free so a key was never presented to me. This may be why it's blocked. The Windows 8 serial key that my 10 was upgraded from also fails (serial was provided for free due to my academic activities): Error installing product key Error code: 0xc004e016.
- Due to a blocked key, the Windows 10 version has reverted back to Build 10240 so I cannot re-update the system I believe.
Should've read and followed http://www.suggest-a-fix.com/index.php?/topic/206-home-building-and-testing-techniques/ - maybe next time...
- Am I right to exclude the components that I have from being at fault?
- What other tests could I do to validate or exclude a culprit?
- Any other ideas on isolating the cause?
I would love to be able to use my PC, it just won't stop freezing...
Your input is greatly appreciated!
