Windows7 Ultimate 64 takes 7 mins to get from windows logo to login
Hello,
I've been googling and trying suggestions from forums on this problem for a couple of days and no luck.....
A couple of weeks ago it appeared that my computer would get a Black Screen of Death after the windows logo. But it turned out that if you wait 7mins (along time to wait with nothing on the screen, not even cursor) it does get to the login screen. I don't think any new software was added around this time, although there could have been some updates.
The same happens if you boot in safe mode, or a Diagnostic Boot from msconfig so I'm thinking its not to do with a service or startup item (??).
I've ran chkdsk, sfc and windows memory diagnostic tool. All OK.
I've tried unplugging everything from the computer including my second harddrive and the DVDrom drive. Still no difference.
When booting into safe mode / diagnostic mode the list of loaded drivers scrolls by, the last one displayed is CLASSPNP then there is a long pause then the screen goes black for around 7 mins before a pointer appears then the login.
Looking at ntbootlogin.txt I see there are many drivers that get added after CLASSPNP but these are not displayed on the screen. The one after CLASSPNP is cdrom, hence me trying to boot with DVD drive unconnected.
I downloaded WinBootInfo and have ran this a few times. The CPU activity graph during boot is interesting. Essentially nothing happens for a five minute period during boot. Looking at the list of SYS and DLL files that load and the times they load there is indeed a 5 min gap where nothing is loaded.
One of the first things to load after the 5 min gap is Luafv.sys which a google says is LUA File Virtulaisation Driver. Is it taking 5 minutes to load this driver? There are other items that are loaded just after the long pause, but I don't know if I'm being simplistic in assuming the pause is due to one of the files loaded just after.
Am pondering doing a complete re-install but really wanted to try and work out what was going on and solve it rather than spend a lot of time re-installing and setting up a lot of things.
Is there a better diagnostic tool that I should be using rather than WinBootInfo?
Any thoughts / ideas greatly appreciated......
Oh, I have:
