I have been having issues with my windows explorer. I have a HP Dv7 Pavillon running Windows 7 64 bit. The issue appeared to be my windows explorer would crash and restart when i ran my mouse cursor over the shortcut icons on the screen quickly; I'd even sometimes experience the same crashes from running my mouse cursor over the task bar or when clicking a program from Windows start.
I tried to idenitfy the problem first by starting Windows in safe mode to test if the problem still occured; it did but not as easily as in normal mode and not without some real prompting after a while.I then reverted back to normal mode, and called up msconfig to attempt to check it by doing the following:
- From the general tab I clicked the Selective startup option and cleared the Load startup items check box, then
- From the Services tab, I selected the “Hide all Microsoft services” check box, and then clicked Disable all.
I then restarted my computer to see whether Windows Explorer keeps crashing or not, to identify if it may have been anything recently installed or added to the computer, since if it was, removing the incompatible ones would stop the Windows Explorer from crashing suddenly. Unfortunately however it still did. I considered at this point that it could be a shell extension problem, broken registry entry(ies), corrupt or missing drivers or even a possible malware or virus. Also whether as a result of 3rd party installations, particularly 3rd party browser extensions/add ons/toolbars.. The only other possibility, although unlikely as my laptop is not all that old, was a hardware problem.
With those above issues in mind I proceeded as follows:
- Checked all my drivers were updated and rebooted, the problem still occurring after;
- Ran CHKDSK from the command prompt then typed chkdsk /r /f and rebooted. The problem remained.
- Ran regedit looking for the following registry HKEY_LOCAL_MACHINE\SOFTWARE\ Microsoft\ SQMClient\Windows\DisabledSessions to disable the subkey Machine Throttling in the right pane but it was not there.
- Ran SFC (System File Checker) to completely scan and fix any corrupted system files if found. No integrity violations were found were after typing SFC.EXE /SCANNOW and rebooting the PC.
I then ran my Avast Internet Security, doing a full scan to check for viruses and it found the following:
all files which were classes as low in severity which I deleted, and also found a number of files stating Error:The system cannot find the path specified (3). I then rebooted my system and the problem still remained.
I then ran MalwarebytesPro with a full scan and found no malicious items.
Next I ran a deframentation of my hard drive and then used RegCure Pro to scan for system problems and there were a few entries found which I clicked to fix. On rebooting my PC the problem remained.
Lastly I did a system restore to an earlier good conguration but the problem remained. I then also got the Error: Bluetooth stack services won't start. I even repeated all of the above to no avail. I should note that sometime before I had been having a WMIprvse problem, which alone was running at between 25 or 40% of CPU and this only stopped when I disabled HP services from the msconfig and rebooted. Around that time Windows explorer did crash but only infrequently.
I may have not followed the order correctly and possibly made mistakes in attempting to overcome the problem. I would appreciate any help, as the problem is most annoying and tends to happen too often for my liking.
