Windows 7 hangs on Welcome screen after power outage (again)
I had posted all this several days ago, but for some reason, my thread vanished. Below is the compilation of two posts I made to the original thread recording the problem and what I've tried to do to resolve it.
This is what I posted on September 18th:
Having a tough time with my Windows 7 Pro computer. Last night we had a five second power outage while I was watching a DVD on my PC. When the power came back on and I tried to book, I got a message telling me to use my recovery disc to repair my computer.
I tried booting normally, and only got as far as the black "Starting Windows" screen. The Windows moving icon never showed up.
Next, I found and booted from the disc. On the System Recovery Options screen, there was nothing listed under Operating System. I selected "Use System Recovery tools" anyway, and then "Start Up repair." After running this once, I rebooted normally and got a login screen. I logged in and the system hung on the Welcome screen.
As it was quite late and I was tired, I went to bed thinking that it would probably load the OS slowly, but it would load, and I'd deal with it in the morning.
When I woke up the next day and checked, the computer was still hung on the Welcome screen.
I restarted the computer and attempted to login in Safe Mode, but after the login screen, it still hung on the Welcome screen.
At this point, I had to go to work, so I shut down the machine.
When I got home, I restarted the PC and pressed F8 and tried to boot into Last Known Good Configuration. I got to the login screen, selected my name, but this time, not even an enter password field was presented.
I shut off the computer and kept reading through the various forums I'd been looking at in search of a solution.
Next I tried rebooting from the recovery disc and selecting the command line option. Then I tried this:
DISKPART
LIST DISK
SELECT DISK #
LIST PARTITION
SELECT PARTITION #
ACTIVE
EXIT
There were 2 partitions, OEM and Primary and I selected primary. Then I tried system repair again which ran just slightly longer. Looking at the Startup Repair Diagnosis and repair details, under "Root cause found," it says:
The partition tables does not have a valid System Partition.
Repair action: Partition table repair.
Result: Completed successfully. Error code = 0x0
Time taken = 6755 ms
Just for giggles, I tried restarting Windows normally.
I got to where I could select myself as a user but again, not even a password field.
I'm at a loss to know what to do. I really need to get back into this machine as I'm in the middle of an important project and I need the data on the PC to work with.
Now this is what I said earlier today:
I started the PC first thing this morning, I figured I'd quickly throw in the DVD to do an in place reinstall. But a screen came up that said it couldn't find disk 0 and offering me several options including pressing F5 for testing and I did.
A pre-boot systems assessment ran and my CD-ROM, Video Card, and a bunch of CPU memory tests all passed, but then the test abruptly stopped with a message saying that it couldn't find a diagnostic partition. I'm assuming that means it couldn't find the OEM partition on my hard drive (although the DST Hard Drive short test passed).
I'm thinking (just a guess) that this is more of a hardware problem than a software problem, but if that's the case, my computer may not be recoverable, at least not without professional help.
Let me know if you have any more ideas. Thanks.
