Windows explorer keeps crashing

Hello all,

I have Windows 7 on a Dell desktop. I formatted it a few months ago. It was working for 2/3 months as if it was new. Since last week, everything is working except that windows explorer keep crashing. There is no way for me to use it. Same problem in safe mode. I tried the sfc scan tool in Dos. He found issues but says that it cannot resolve them. I also tried all the restore points available but the restoration is always blocked by some error messages. I have no access to msconfig. The detail in the error message says that the dqveclnt.dll is damaged. I tried to move the explorer.exe file to another folder but I cannot do any moving manipulation as explorer crashed immediately. I cannot format again since there is no way to back up without going into the explorer. There should be a solution? Is it a malware or a virus? Malware bytes did not find any threat. I also run cc cleaner. Unfortunately nothing helped so far: Let me know what you think and how I can fix this.

Lets do the basic fist.
- Schedule a disk check. Open a CMD window and type chkdsk c: /f . it will ask if you want to schedule to next start = yes. Pay attention on the results, specially bad blocks or bad clusters.
- Do a System File check again. Open a CMD window and type sfc /scannow

Thank you. I am doing a sfc : scannow again. Where do I get the report once it is done?

The sfc /scannow is done. It says windows resource protection found corrupted files but was enable to fix some of them
It says to consult the cbs.log but how can I open the log without access to windows explorer. It is a real nightmare. HEEELP :/

I made progress!!! I did a clean disc and removed what I could there. There was a 20 go from a previous windows installation. I create a new user profile. Then I reboot the computer. Upon reboot it did a check disc and then before starting, it did some reconfiguration of windows (including windows update). If I log with the new user account; the problem is GONE! Windows explorer works!! However, on the old user profile, we still have the problem. Any idea?

Well correction. Windows explorer in the new user account is working as long as I do not go to my computer. If I click on my computer, then it crashes again

Do you see a solution?

Good you fond a way to have Explorer.
Did you run check disk?

You can move all the data files to the new user you created and then delete the problematic account.

Hello :)
Try to make a system restore and back to a restore point 2-3 weeks back.

Edit: There's nothing to lose by testing, if it can resolve it provisionally, so you can access to backup your data

Actually the explorer in the new account works as long as I do not click on the mycomputer. If i do, then same crash story. All restoration attempts I tried does not work

I am stuck. What can I do?

Then I can only recommend to make a bootable USB stick with Linux Mint and copy out all your data that way.

Edit:
I ran into the same thing as you, but with Windows XP(ten years ago) system restore worked for me that time.
When I ran into January's update, the only solution was save my data with Linux, then a reinstallation of windows
