No Problem, I meant to use CCleaner just to clean out cache and temp files it is very good at this, not to use it for registry cleaning, although it is one of the safest to use for that too,plus it makes a backup for the registry in case.
I would never use other Registry cleaner or these system care ones , true they will make matters worse, you really need to know what you are changing when you use any software like this, tread lightly.
Yes doing clean up through Windows is pretty efficient although i find CCleaner better,IMO.
IMO youtube can have maleware,spyware and viruses, then to worry more about getting hacked from it.
Chkdsk would be better done through run as Administrator command prompt ,at a command prompt chkdsk /f /r
Then you can run a sfc /scannnow at admin command prompt also.
Do not think this is your problem, but is good to run every so often so you can do it way i explained it is more efficient this way.
After you do a chkdsk there is a way to see the report, click start and select run, type powershell.exe
In PowerShell, copy and paste the command below, and press Enter.
get-winevent -FilterHashTable @{logname="Application"; id="1001"}| ?{$_.providername –match "wininit"} | fl timecreated, message | out-file Desktop\CHKDSKResults.txt
This will give you a report on your desktop of the previous chkdsk.
In firefox under tools, select add-ons ,then select plugins on the right, in blue highlight it says "Check to see if your plug-ins are up to date".
From there it will let you know which ones are up to date, you should see Adobe Flash there.
Try a scandisk ,chkdsk and update the plug-ins on browser see what happens , too many addon ons may slow performance on browser i feel.
