On an Acer Aspire 7741G laptop, during startup, the computer stays stuck on a black screen before the Windows logo appears. It also affects safe mode, in fact the black screen is even before F8 procs the mode selection menu.

During this black screen the drive activity led is lit.

Note that the black screen isn't the one with the blinking cursor, it appears right after.

So far I tried sfc /scannow and chkdisk, but nothing changed. There was no restoration points previous to this problem, so I can't try that.

Edit :

As advised by a comment I checked the event log :

  • I can see that there are 2 disk bad blocks errors and a NTFS error "the default transaction resource manager on volume \?... encountered a non-retryable error and could not start". Those events take 10s to process.

  • I have a Kernel-General error that takes 31s to process right after winlogon : " {Registry Hive Recovered} Registry hive (file): '\??\C:\Windows\ServiceProfiles\NetworkService\NTUSER.DAT' was corrupted and it has been recovered. Some data might have been lost.". From what I read replacing this file with the one of another user would fix the problem but will basically erase all personnal customization ... Is there another way ?

I believe that you are experiencing serious disk problems. You may also verify this by having a look at the S.M.A.R.T. data, using a product such as Speccy.

I would suggest at first to take good backups of all your data, installed products and their serial numbers, just in case. You might also take a backup disk image, using a product such as the AOMEI Backupper Standard Freeware, then create its boot CD or USB and ensure that it can boot and that it can see the disk on which was written this backup image.

Then you may choose between replacing the disk and trying to revive it.

You may replace the disk by an identical one and reimage back your installation using the AOMEI Backupper boot CD/USB.

You may try to revive the disk by doing a slow format of it. The Windows installation boot CD/USB can do that for you, but rather than installing afresh you could just reimage your disk as above. But if disk errors happen again, then the disk must be replaced.

As you say you got 199 S.M.A.R.T. errors, here is what Acronis says about this error:

Current Pending Sector Count S.M.A.R.T. parameter is a critical parameter and indicates the current count of unstable sectors (waiting for remapping).

This is a critical parameter. Degradation of this parameter may indicate imminent drive failure. Urgent data backup and hardware replacement is recommended.

You currently have 199 bad and unreadable sectors on the disk.

Danger, Will Robinson! Save your data and replace the disk.
