PC fails to start after Windows 10 installation or reboot.
PC fails to start after Windows 10 installation or reboot.
This situation is going to be quite challenging. Here are the key points:
- The system booted smoothly initially with all devices connected and the monitor linked via display port.
- BIOS functioned well at first, but later became sluggish.
- After several attempts, the monitor connection failed entirely once.
- The PC would shut down unexpectedly after a short period of use.
- VGA status light would activate before shutdown, indicating a potential graphics card issue.
- After adjusting settings and re-seating components, the problem persisted.
- Peripherals seemed unaffected until the GPU was removed.
- All connections appeared correct during troubleshooting.
- The BIOS logged a PCI-E connection but didn’t show the device name.
- I followed multiple steps to resolve the issue, but nothing resolved it.
Connected D-Port via MB or GPU? Was the Intel UHD disabled? What temperatures do you see when you open the BIOS?
I tested both connections. The Intel UHD remains enabled. BIOS shows CPU temperature near 42°C, which isn’t too high.
I checked the issue at a nearby PC repair service after completing all troubleshooting steps I thought I could handle. After a full disassembly and a BIOS update, the problems appeared resolved. It might have been a poorly secured CPU cooler, but that doesn’t fully explain the situation since the PC ran for extended periods multiple times. The BIOS update also corrected the behavior of the USB2 header connected to the cooler pump, ensuring it lit up properly as intended.
