Following BSOD I ran  "Windows troubleshooting"   and got a message

about Power options  and " Superfetch not enabled "

 

Tried starting Superfetch manually , and get this every time :-

" Error 2 : The system cannot find the specified file "


Ran sfc /scannow from Command Prompt      100%  OK

Then CHKDSK (Check Disk)  same result .... all good

Ran Malwarebytes ( just out of curiosity )  ..... all clean

Tried rebooting  ( twice ) .... MUCH slower booting than before BSOD


About 4 minutes before the BSOD , I copied some text files from Desktop to a 16GB USB stick ,

but did nothing else apart from everyday tasks.

I ejected the USB before and got the usual " Safe to remove ......  etc "

There are absolutely no other problems that I can see other than the very slow boot.

I noticed this on http://support.microsoft.com/kb/2727880

HKEY_LOCAL_MACHINE
SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\PrefetchParameters. In the right pane double click on the Enable Prefetcher entry,
and change the DWord value to 0for Enable Prefetcher . Click on OK, and reboot the PC.

The value of DWord for both Prefetcher and Superfetch  is  3 , which should be "Cache everything (default)"
but I haven't changed anything.

 

What is going on here ?

Can anyone explain the "Error 2" message above ?

Anyone got any tips / hints ?

 

Thanks for any help

How did you go about manually restarting the Superfetch?  

 

If you tried to start the Superfetch in Services and got that message try running sfc /scannow.

 

The sfc /scannow command scans all protected system files and replaces corrupted and incorrect versions with correct Microsoft versions.
 
Click on the Start orb startorb_zps06e1f985.png and type cmd in the Search programs and files box.
 
In the pane above the search box Programs will appear with cmd below it, right click on cmd and choose Run as administrator.
 
If you are prompted for an administrator password or for a confirmation, enter the password, or click Allow.
 
A page similar to the one below will open.
 
commandprompt_zps212bc71a.png
 
Type in sfc /scannow and then press Enter to start the scan.  Please notice the space between sfc and the /scannow.
 
If the scan finds no integrity  problems in the first portion of the scan it should stop, to be sure that the scan has stopped wait five minutes, then type in exit and press Enter to stop the scan.

Thanks Arachibutyrophobia

 

What you suggest is precisely what I did first ( see original post )

 

I am starting to wonder if Superfetch IS actually running ,

and that attempts to start it manually ( via Services ) is generating a false error message ?

 

Evidence supporting this : Registry entries are correct

 

Evidence against :             Running Windows "Troubleshooting" routine says that it is NOT running.

                                          AND boot times for the laptop are still slower than before BSOD incident

 

It would be really good to be able to check this independently eg with "Process Explorer"

but I think maybe it would be running as an svchost process and I don't know how to identify it.

 

PS . I tried  to paste a screen shot , as you did with the cmd box , but got this message :-

After a few hours of researching I found this :-

 

http://social.technet.microsoft.com/Forums/windows/en-US/e01a636d-cac5-4cb6-8468-74bb9ab85be2/superfetch-is-not-running?forum=w7itprogeneral

 

It turns on Prefetch again ..... No doubt about that !

 

Time will tell if it stays fixed .

 

 

Errr !    NOT

===========

 

 

I found and tried this :-

 

http://www.sevenforums.com/performance-maintenance/156744-superfetch-will-not-start-i-keep-getting-error-can-anyone-help.html

http://www.majorgeeks.com/files/details/tweakprefetch.html

 

After reboot the problem returns ..... I think it has something to do with access to a file in the Windows\Prefetch folder

                                                          permissions changed ???     or registry key corrupted ???

 

Anyone had similar problems ??  ..... tips or fixes ??

In my last post I asked how you had restarted the superfetch, specifically if you had done so in Services.

 

When you restarted superfetch did you click on apply and then OK?

 

 
 
***This is a diagnotic tool for Windows Vista, Windows 7, and Windows 8.  This will not repair your computer, but it may point to where the problem lies so that a repair can be made.***
 
Warning:  Disabling items in Services or Startup may leave your anitivius disabled until the process is ended.  For this reason I would suggest that you perform this process off line.
 
Step 1
 
(1)  Click on the Start orb startorb_zps06e1f985.png, then type msconfig.exe in the Search programs and files box.  
 
(2)  When msconfig is seen in the pane above the search box and under Programs, right click on it, then click on Run as administrator.
 
msconfig2_zps2e854ee3.png
 
If you are prompted for an administrator password or for confirmation, you should enter the password or provide confirmation. 
 
Step 2
 
(1)  Click on the General tab.   
 
(2)  Click the Selective startup option. 
 
(3)  Remove the check mark in the Load startup items  check box. 
 
Cleanboot_zps3b042516.png
 
Step 3
 
(1)  Click on the Services tab. 
 
(2)  Place a check mark in the Hide all Microsoft services check box, this will remove the Microsoft Services from the list but will still be running. 
 
(3)  Click Disable all, this will remove all of the check marks in the Services list, then click on Apply, then OK.  Click on Restart in the window that opens.
 
Caution:  By disabling the Services your antivirus will not be active, for this reason I suggest that this process not be run while online.

If the problem does not reoccur after the reboot continue with the process of elemination to find the Service which is causing this in Option A.  If the problem does reoccur after the reboot go to Option B.
 
Option A
 
**The following is a process of elimination to find the Service or Startup item that is causing your problem**.  
 
*  If the problem does not reoccur after the restart go back to Services and place check marks in half of the boxes and restart the computer.  
 
*  If the problem still does not continue return to Services and remove the check marks that were added, then place check marks in the remaining half of the boxes and restart the computer.
 
If the problem resumes after a restart in one of these halves, you will procede with this process in the half where the problem occurs.  If this does not continue in either half you should repeat this process in Sartup
 
*  In the half of the Services that the problem is found, remove one check mark at a time and restart the computer to see if that  is the Service causing the problem.  Continue to do this with the Services untill the service causing this problem is  found.
 
Option B
 
Search Startup itmesIf the problem is not found in Services, remove all of the check marks, click on the Startup tab and repeat the search process there.
 
Caution:  If this is a laptop, make sure, you do NOT disable any keyboard, or touchpad entries.
 
If this problem is found post the Service or Startup item that is causing it. 
 
 
An aside:  There are two ways you can post an image here.  
 
1.  Just below the area where you write text in a post there is the Post button, to the right of this is More Reply Options
 
Post2_zpsf05c0430.png
 
When you click on More Relpy Options  you will see Attach Files and Browse, click on Browse, this will open Pictures on your computer, click on the image you made with the Snipping Tool, then click on Attach This File, then Add Reply.

2.  You can use a website like Photobucket to host images.  You will get a link from that site, then post it in your topic.

Thank you once again Arachibutyrophobia , for your continuing interest and help with this issue.

You wrote :-

 

In my last post I asked how you had restarted the superfetch, specifically if you had done so in Services.

 

When you restarted superfetch did you click on apply and then OK?

 

Yes , I restarted in Services ( as Admin ) , but NO I could not click on "Apply" because it was "greyed-out"

and after clicking start , a dialog box opened giving me the error message as described in my first post,

and I could not proceed further .

 

I still have a niggling suspicion that that the root of this problem may be in file/folder permissions being corrupted.

 

This is partly because when I DID succeed in re-starting Superfetch ,( by  emptying the Prefetch folder ) a dialog box told me I didn't have

permission to access the folder (%SystemRoot%\Prefetch) and asked me to click on "continue" , which I assume was an elevation.

 

What do you think ?

I am by no means a Windows professional , but by the same token , definitely not a beginner,

.....   so I really appreciate your input.

 

It's not that my system is  in any real way dysfunctional , it's just that as a scientist , with a previously smooth , slick , clean and fast

system ...... little things like this bug the hell out of me !!!!

 

Do you know what I mean ?

Anyway , thanks again ,

It's possible that your administrative account is corrupt.

 

Create another administrator account, log into that account and see if that works.

Good Thinking !!

 

That will be a quick and easy way to test my idea about file/folder permissions .

 

I am in no way knocking the use of the multiple tools and posting of scans on this forum.,

but there is just SO MUCH stuff to grind through.

I guess for many people who come here with computer problems , and for those who want

to help them , its the easiest and most reliable way .

 

It's just that personally , I prefer an "analytical" approach coupled with sound deductive reasoning ,

"Sherlock Holmes Style " , if you will .

 

I'll check it out and post back.

 

Incidentally , boot times are back to normal !!!

although Superfetch is still showing as not running in Services and still pops the original error message

when I attempt to start it manually ( and it still shows as " Automatic" in the "Start" column of Services )

 

I recall reading somewhere that Superfetch indexes progressively and it may take time to see the speed

advantages .

Still puzzling me !

 

Anyway , thanks again.

 

PS .     I also take the " Marxist" view of joining clubs !

The analytical  approach is the ideal, but sometimes with computers you have variables that have to be explored to reach the point where you can be analytical.
