Dell Optiplex 745 Small Form Factor: How do I fix my corrupted OneDrive?

Fri, 09 Oct 2020 20:53:53 -0700

The computer I have is the Dell Optiplex 7010 but it looks lile the 745 Small Factor. Mine wasn't listed as such. My Windows OneDrive got corrupted. So now I can't get Windows to boot. When I turn on the computer, Windows goes right to Attempting Repair mode. I have tried all the advanced options except command prompt. The computer didn't come with any discs. I don't know what command (s) to enter to fix the Windows Operating System at the Command Prompt. What do I do from here, short of ordering a repair/reinstall disc? I can't afford a new system from Windows and I don’t want to buy an OEM repair disc that might not even solve the problem. Help, please!

Dell Optiplex 745 Small Form Factor: Audio driver keeps turning off - Dell OptiPlex 1070

Thu, 16 Jun 2022 01:44:43 -0700

NOTE: You didn't have my model as an option. This is NOT the 745, but 1070! About 30 seconds after the audio ends, the audio driver turns off with a faint, thump or pop. When playing audio again, the driver comes back on with a pop (rear speaker port) or a loud thump (front port) - even if the speakers are muted. I've tried headphones, headsets and external speakers. I've reinstalled Windows 10, reinstalled / updated audio drivers, changed audio settings galore, updated BIOS and Dell sent a tech out to replace the motherboard.
