Recently I've been having problems with the boot time of Windows 8.1. Here's the information of the boot trace:

enter image description here

As you can see the PreSMSS phase takes way too long - over 96 seconds - and the ExplorerInit phase 17 seconds which I think isn't normal since my system used to take 30 seconds or less. Also the PostExplorerPeriod and TraceTail durations are set to -1. Is this some kind of bug?

Can somebody please help me?

PS: I can give all the needed information of the .xml, I just didn't post it right away so that the question's body isn't excessively long.

  • Have you Googled anything on slow boot time regarding PreSMSS? – Matthew Williams Feb 20 '14 at 17:05
  • @MatthewWilliams I have, extensively. I found that boot delay in that phase is due to delay in initializing some device. I looked in the pnp node and indeed there's one device that takes a really long time but it's named: "PCI\VEN_8086+DEV_1E03+SUBSYS_C652144D+REV_04\3+11583659+0+FA". I googled it but no information regarding what device this might be was found =/ – PML Feb 20 '14 at 17:14

PCI Vendor 8086 is Intel, and the device (DEV) 1E03 is:

DEV_1E03

Intel(R) 7 Series Chipset Family SATA AHCI Controller

Intel(R) 7 Series/C216 Chipset Family SATA AHCI Controller - 1E03

Check your SATA cable, or maybe your disk is going bad.

You also may want to go to the Intel Driver Update utility and make sure you have the latest storage or chipset drivers from them.

  • Well after my initial freaking out moment when I thought I would have to be without pc for a week I checked the drivers. Indeed they weren't up to date, although they worked fine until a day or so and I don't believe I've updated any other driver. Problem fixed. The PreSMSS phase now only takes 4 seconds. Thank you! – PML Feb 20 '14 at 20:16
