My Windows 7 just restarts without giving me a BSOD.

When it reboots, it will hang sometimes and you have to let it rest. Sometimes it will print a message saying that Hal.dll is missing or corrupt. When it does restart I can't run a backup or a clone drive – it comes up with constant errors.

I tried to run chkdsk – it says everything's clean.

What is really puzzling is SyncToy on a different drive hangs half way through and won't run either.


  • OCZ SSD Agility 2 for C drive
  • SATA HDD for programs, documents on D drive
  • MSI AMD 880 chipset

Event viewer says something about critical power failure I/O operations and "Event ID 14 volsnap" – but that is just telling me the computer powered off which I already know.

There might be some hardware fault. The errors seem to point it to the disk and the cables to the disks. It can also be memory or CPU. I would do some system stress test under an OS on a USB stick and rules those parts out. – Oct 14 '12 at 22:19

Hal.dll is a file critical to logging on to Windows.

Try checking the drive for errors - a guide is available here.
