MickinMD ★ Posted April 14, 2018 Share #2 Posted April 14, 2018 Did you change the HD or a Plug and Play device or are parts just failing? Link to comment Share on other sites More sharing options...
Longjohn ★ Posted April 14, 2018 Share #3 Posted April 14, 2018 Wheels can tell you how to fix that. It will probably involve eating cookies and spending all of your cash. 1 Link to comment Share on other sites More sharing options...

No. I did a Windows update followed by a restart. The results did not indicate a problem. I went out to work for the day and when I came back, Windows would hang during start. I went into safe mode trying to get it to start and it kept hanging while loading "classpnp.sys". So I worked around that and the computer kept trying to boot from one of my storage drives. So I went into the BIOS and reset all that default settings. Trying to repair the "C:" drive from safe mode, it kept trying to boot from the storage drive. So I went into safe mode to the "last known good configuration" and ran a chkdsk /r on the storage drive. Then I rolled back off of the latest Windows system update (W7 64 bit) and that seemed to let it run. This AM, I ran sfc /scannow and chkdsk /r on the system drive and it appears that the system is running normally. No bad sectors on this drive. Weird.

Unfortunately, the advice to fix the problem is all over the place. Everything from doing a fresh install of the OS to doing a full memory check.

donkpow Posted April 16, 2018 Author Share #9 Posted April 16, 2018 The cause of this failure to start properly is proven to be a "software patch". This is the one I rolled back off of. Link to comment Share on other sites More sharing options...
Razors Edge ★ Posted April 16, 2018 Share #10 Posted April 16, 2018 I'm just gonna go ahead and assume it is user error. Tom Link to comment Share on other sites More sharing options...
Scrapr ★ Posted April 16, 2018 Share #11 Posted April 16, 2018 I think I see the root cause. (windows update) I finally got my machine going after trying to work around on Creators update. And by me I mean my IT on call guy. Clean install on a SSD that I had lying in the drawer Link to comment Share on other sites More sharing options...
