In the normal sequence of events you see:
- Starting Windows and Windows logo
- Black screen
- Black screen with arrow (which you can move with the mouse/touchpad)
- Please wait
- Welcome
- Windows logon screen
The computer I am working on never gets past stage 3, no matter how long you wait. You can move the arrow/pointer around with the touchpad but there is no response to Ctrl Alt Del. In Safe Mode you see the 'drivers loading' screen then arrive at the same
point of a black screen with arrow and go no further.
The computer originally ran Vista but was upgraded to Winows 7 (so runs the 32-bit version). It has worked perfectly well for several years with no recent changes. It suddenly shut down in the middle of a game of Minecraft and has refused to start since.
There was a spare 'Data' partition so I installed a parallel copy of Windows. This works perfectly so no indication of a hardware problem. I ran a virus scan on the faulty partition which found and removed a few bits of adware but nothing of significance;
no good. I ran chkdsk in all five stages on the 'bad' partition but this found nothing and had no effect.
I tried the F8 - Repair My Computer option. This found nothing to repair. Oddly, the advanced options like System Restore and CMD prompt were not available - I've never seen that before. So I booted from the Windows Disc and tried System Restore but it
said there were no restore points - I take that to be some sort of error rather than the truth. But this rules out the System Restore Option.
I found a backup copy of the Registry files in a subfolder of the Config flder where they reside. The backup was a few weeks old so dates back to when the computer was working. But substituting the backup copies for the current files had no effect.
I tried Last known good and VGA mode without success. All the drivers seem to load according to the log I made. And if I look at the Event Log from the faulty partition I cannot spot any difference before and after the fault arose. Indeed events continue
to be logged for some time during the black screen with pointer phase, as if the computer has not really noticed that it is not working properly.
Any suggestions other than re-installing Windows which, effectively, I have already done. I just want to get the old Windows installation working. I have searched online for a solution but not found one, although there are other reports of the same problem.
