I’ve been battling with my machine for weeks now, hoping for community’s ideas or experience.
My PC usually fails on boot and enters a restart loop. Typically, it passes the ASUS (mobo) screen and shuts down during the Windows load screen with the wheel spinning. The PC will auto-restart shortly after shut down, and repeat failure. The shut down isn’t exclusive to the Windows load screen; it’s also occurred prior to reaching the Windows screen or after entering ASUS UEFI. Generally, it will shut down between 3-15 seconds after startup.
The caveat is this: about 10% of the time, it boots and works completely fine. The Windows load screen has come to serve as a “gate” for me: if it doesn’t fail here, it’s going to work. The PC has never shut down after reaching the Windows user log-in screen. Everything looks normal after successful boots (temps, hardware installed, etc.)
Here is what I’ve already tried:
- Cleaned / removed dust from interior, components
- Reseated components & wires (GPU, PSU, RAM x2, wireless card, hard drives x2)
- Re-applyed thermal compound to CPU, reseated Updated mobo drivers & BIOS
- Updated GPU drivers
- Reset CMOS (removed battery, reseated)
- Reset motherboard overclocks
Specs:
- Windows 10 Home 64-bit
- ASUS Z97-A
- Crucial 128 GB SSD (boots from this drive)
- GeForce GTX 970
- i7 4790k
A motherboard beep speaker is installed; it beeps 1 short time as it starts-up, which according to ASUS means the device is OK and booted normally.
Some ideas I’m still considering:
- Reseating everything again
- Replacing the CMOS battery with new
- Updating more drivers (hard drive, etc.)
- Reformatting / reinstalling Windows
Thank you for any help & consideration.
