Troubles with your PC internet and display connections.
Troubles with your PC internet and display connections.
Hi everyone, I'm having a couple issues, wondering if anyone more tech savvy than I am knows where to begin. A couple weeks ago, I had two problems begin back-to-back. My PC lost connection to the internet, and shortly after, the monitor went black. C onnection - I tried all the normal stuff (reboot router, reboot PC), and nothing worked. I ended up needing to reinstall the driver, and it connected right away after that. I have since had to reinstall the driver another 3-4 times for the same reason. Monitor - I tried powering off/on the monitor, it didn't work. I could still access the on-screen menu for the monitor itself, but it didn't recognize that there was an HDMI connection coming in. I tried plugging that same HDMI cord into another monitor, and nothing worked there either. After rebooting the PC, the HDMI connection was recognized by both monitors. This has also happened another few times, with the same fix. Since then, both of these issues having been happening periodically - sometimes together, sometimes not.

Prior to that initial day, I never had issues with either. Thanks in advance for any advice. Tyler
@Supersonicwolfe Thanks for your help. I'll be honest, wasn't familiar with those tools prior to today. I have since run both. I'm unfortunately having trouble deciphering the output. The stuff in the command prompt seems fairly straight forward... looks like the DISM stuff didn't run into any issues, but SFC did. :\Windows\System32>sfc /scannow Beginning system scan. This process will take some time. Beginning verification phase of system scan. Verification 100% complete. Windows Resource Protection found corrupt files and successfully repaired them. For online repairs, details are included in the CBS log file located at windir\Logs\CBS\CBS.log. For example C:\Windows\Logs\CBS\CBS.log. For offline repairs, details are included in the log file provided by the /OFFLOGFILE flag. Would there be certain things I should be looking for? The "CBS.log" file is absolutely crazy long... over 500k word count according to Microsoft Word. I tried using CTRL F to search for /OFFLOGFILE since it's listed above, but didn't get anywhere with that - no results found.
@Whatisthis Thanks for the feedback. I actually wondered about that just in general. I upgraded the graphics card from a 1080ti to this one just a few months ago, and wondered about updating the PSU as well. Anything specific I should look out for when purchasing a new one? -- The error log is crazy long. I attached it here, unless it is better to just post? Seemed like a ton.

Thanks for sharing the link and your thoughts. I'll review both options. Any insights you have on the Event Viewer would be appreciated.
Download DDU Start in safe mode and restart it. Install the newest GPU drivers. Open an elevated command prompt with admin rights by searching for cmd and right-clicking to run it as administrator. Execute DISM /Online /Cleanup-Image /RestoreHealth, then sfc /scannow and chkdsk /r. These steps should resolve most Windows and display driver problems. If issues persist, consider a full Windows reinstall as a final option.
If the message indicates SFC is fixed, stability should improve. DISM command "DISM /Online /Cleanup-Image /restorehealth" helps restore system image integrity. SFC then verifies and replaces mismatched files with the correct system image. Another suggestion was chkdsk /r to scan disk file system errors (available in the drive properties/tools section). Because of a display driver crash, another post recommended using DDU to cleanly remove the faulty driver and its data before reinstalling. If this didn't resolve your problems, a graphics hardware issue might be present.
You're welcome to both of you for helping out. I usually consider myself pretty tech-savvy, but this situation shows me how much I'm mistaken. I tried all the advice given, ending with a Windows reinstall yesterday because nothing worked. The monitor lost its HDMI signal three times in about half an hour today. When I used the same cable and connected to another device, it worked instantly. I've ordered a new power supply unit that should arrive tomorrow to check if that helps. If not, I'll start looking into GPU options. Any other hardware suggestions besides a full replacement would be great—thank you for your support.
