I'm working on a friend's laptop, a Dell Inspiron N5050. I updated the machine from Windows 7 --> 10 (64bit) a few months ago. Things were working fine. A few days ago, the laptop fails. Now on normal power up (after the bios splash screen), you hear no drive noise, it just goes to a black screen with a single flashing dash / cursor about three lines down in the upper left hand corner of the screen. If you hold down a key, after a few seconds you hear a repeated click. The cursor never moves. It just blinks.
I did a Dell bios diagnostics test (built into the bios). The test is called a "ePSA Pre-boot System Assessment" Not sure what PSA stands for. Diagnostics reveal no errors, including Hard Drive and memory.
On a different laptop I built a Windows 10 repair disk (Control Panel --> File History --> System Image Backup [left hand margin] --> Create a system repair disk) . When I boot the problematic Dell Inspiron N5050 to the repair CD, the screen shows "Non-System disk or disk error Replace and press any key when ready" There were no problems reported on the normal tests. I'm running the lengthy Thorough Test Mode stuff right now; that test should take a few hours to run. I'm at a loss as to what to look at next...
I don't understand how that Windows 10 repair disk actually works. When I boot my windows 10 laptop up with that disk, I can see the CD start, but after a few minutes the thing reverts over to my Windows 10 hard drive. This is definitely different behavior that I see on the defective laptop. (I wanted to verify the CD was burned correctly...)
Any hints on how to fix a broken Windows 10 install? (and / or mystery hardware issue?)
thanks for any assistance...
