System powers off completely while display remains active and cooling fans continue operating.
Hey there, I recently switched from W8.1x64 to Windows 10 after an upgrade, but I cleaned the installation afterward. Now I’m facing some issues, and I’m hoping you can assist. The main problem is that sometimes I can’t shut down or restart my PC. Usually I press Start -> Shut Down / Restart, but after a brief pause the screen goes black. Fans, motherboard, and CPU are still active, so I can still see the CPU temperature on the motherboard LCD. This suggests the system isn’t actually powering off. It happens occasionally, which makes it hard to figure out what’s causing it. Do you have any suggestions? What should I check or monitor? Maybe look into Windows logs to track this down. A bit more info about your setup would help: MSI Z97-G7 Mobo, i7 4790K, Corsair Vengeance DDR3 2x8GB at 2133MHz (XMP), Samsung 240pro 256GB, Asus PCE-Ac68 Wi-Fi card. I’m running Windows 10 x64, Office 2013, Symantec Cloud antivirus, Firefox, and GTA V. No other programs are running. Thanks in advance for your help!
I've also encountered a comparable problem twice after switching to Windows 10. Besides that, I often experience periods where no updates appear, even when I power on my PC. All other components like fans, keyboard, mouse work fine, but the display shows "DVI not found..." and then becomes blank. Someone can assist with the earlier issue.
Sumitmak, here’s what you should consider. After turning off your PC, you mentioned a strange state and wondered if Norton antivirus was involved. It seems the issues might have worsened after installing Norton. You cleaned the system three days ago and it worked fine, but the BIOS flashing and CMOS reset didn’t help. Before the clean install last Sunday, you flashed the BIOS, cleared the CMOS using the clear button on your motherboard, and set everything up from scratch. Thinking about reverting to Windows 8.1 makes sense, though it’s been 30 days. It might be worth trying that option.
I’m sure you can start fresh without any issues. In fact, I usually opt for a clean install because I’m not confident in the upgrade or downgrade steps. The main concern is whether your W81 key remains valid after the reinstall.
The W81 key is a function key often used in Windows settings. The Windows key on your keyboard is typically the space bar or the "Windows" key.
