Starting a while ago, my computer began hanging indefinitely a few minutes after showing the login screen. This only happens after the computer has been off for a few hours.

Normally, after restarting the computer, it will work fine after that, but it's quite often that it'll happen a second time in a row, though it rarely happens a third time. This also happens when waking the computer from sleep mode (after sleeping for a few hours). Everything works fine in safe mode, so I've begun to believe that it's a driver problem, but I'm unsure how to go about fixing the problem. Because this problem only occurs after hours of being turned off, it's tedious to diagnose. Doing a clean boot (disabling programs and non-Microsoft services) does not solve the problem.

What I've tried

  • Booting up with Boot Logging turned on. Output
  • Doesn't hang while in safe mode
  • Doesn't hang while in safe mode with networking
  • When I unplugged the computer and moved it somewhere else, it stopped hanging for a few days, but the behavior has returned.


  • Operating System: Windows 7 Ultimate 64-bit
  • Processor: Intel Core i7 CPU
  • Video card: NVIDIA GeForce GTX 260 (driver version 285.62)

Does this happen in safe mode? Is the CPU high, or memory climbing before it occurs? – soandos Nov 28 '11 at 21:39
It works fine in safe mode, but I'm unable to notice any CPU changes because it usually happens while I'm logging in and loading the desktop because I try to enter my password quickly in order to use the computer faster. – Kenan Nov 29 '11 at 0:05
Can you create another user and try logging in from there? – soandos Nov 29 '11 at 0:08
Well, it still freezes at the login screen if I take too long to enter my password (entering my password doesn't help either way), so I don't see how a new user would help. – Kenan Nov 29 '11 at 2:47
in safe mood use msconfig to swap to a diagnostic startup. do these issue happen then> – soandos Nov 29 '11 at 2:49
