I think CCleaner screwed up my computer...

[QuestionableUsername]

I cleaned registry and programs and all with CCleaner about 5 times total. Now I think that came back to stab me in the back because I believe that my Steam (more specifically VAC), my League, and my Google Chrome is not running as well.

Is there any way to fix this or do I have to do a clean install of windows?
I've tried repairing my system with command prompt. No luck.

Despite what any fanboy might say to you.. always avoid using any type of Registry Cleaner... they do more harm than good. Some have an undo function that might work half the time... but if not, just restore from a backup (or reinstall Windows if you never did that).

System Restore might also work.

In your search box of windows type CMD.
Right click on the search result Cmd, and run as an admin.

In the command prompt window type: sfc /scannow.


If you have not tried this do so it should fix all of the errors and problems you are having.
As much as registry cleaners seem like a good idea, as you have found out they often create more problems rather than fix them.

I have a backup from like 3 cleans ago, doubt it's gonna do that much good but i'll give it a try. How do I restore it? It's a .reg file.

Just did it and windows thinks there are no problems.

Steam cannot connect to VAC, Chrome is lagging way too much (this is not normal for my PC), and League of Legends had some quirks with loading in the shop. Also Windows doesn't want to update for some reason...

sure you didn't got a malware? did you check the cpu/hdd/gpu usage and temperature ?

Doubt it, I have bit defender and malware bytes (both pro version).

because this don't sound like registry issue

Did you do something after or did the problem start right after your run ccleaner?

After I ran CCleaner, the more I ran it the worse my computer got.

Ccleaner should not do more the more time you run it.
Was there a reason you run it the first time? do you have system restore? your hardware spec?

 

[rgd1101]

look like you have issue with your pc long before.

No system restore sadly.

Reason I ran it the first time...I forgot, I think I did it because my friend convinced me it would make my computer faster. Both of our computers were running worse afterwards.

 

[rgd1101]

where did you downloaded it from?

 

[Cherie1251]

I bought the ccleaner it says on my bank account from Piriform

I have the same problem, because it was slow online it said to use this CCleaner, now it is sure bad, can't play games, it freezes

Maybe the issue you have is not ccleaner, sound like you have an issue before you install them. need to fix that. And please start your own thread.
