Why does my computer keep shutting off during a full scan? Sometimes within a minute sometimes when its almost done?

It seems to be able to do a quick scan just fine, but when prompted to do the full scan, it starts then my computer shuts off before it finishes? I have ran tweaking and done a disk chk and all seems to be repaired and fine but it still can not do the scan? Thanks!

HI LJS,

 

Make sure your system is set to run until the scan finishes - no power saver options enabled and if a laptop, running off AC power and not the battery.  If the PC shuts down, that will cancel the scan.

 

I recommend you check your hard drive for general or system file corruption as follows:

 

Go to Start / All Programs / Accessories / Command prompt and right click on command prompt and click run as Administrator (the last part may not be needed in XP, if there's no run as Administrator option when you right click, then just open the Command Prompt).



Type sfc /scannow and enter and let it run. It will scan and try to fix some of your system files. Hopefully it will complete with no corruption it could not repair (if there is such corruption post back here or try to analyze it to find the problem file(s) using

http://support.microsoft.com/kb/928228).  Note you can't open the CBS.LOG file there and can't even open the sfcdetails.txt file if located there and need to copy the sfcdetails.txt file to the desktop to be able to open it.  If it shows anything, please copy it to your SkyDrive account with everyone permissions and post a link to it in your next reply.  Here's how to do that: http://answers.microsoft.com/en-us/feedback/forum/feedback_other-na/how-to-insert-images-in-ms-answers/94a5cb36-a21f-4a6a-b266-611cf6c910c8 (just use the file instead of the image).

 

While in Command Prompt, type chkdsk /f /r and enter and let it run. It will want to schedule itself to run at the next restart. Answer yes and then reboot to run the program. It will scan and try to fix any corruption or bad sectors on your hard drive and mostly remove that as a potential cause.

 

Then let's do a more throrough test of your hard drive.

 

To test your hard drive, try HD Diagnostic (http://www.carrona.org/hddiag.html) or this test: Hard Drive Diagnostics Tools and Utilities (Storage) - TACKtech Corp (http://www.tacktech.com/display.cfm?ttid=287) or go to the website of the hard drive manufacturer to see if they have a specific diagnostic utility for your drive. That will provide better proof the drive is OK.

 

When done, defragment the hard drive as a final step to restore it to its best operating condition.

I hope this helps.
