I have recently built a new PC, and it worked fine for a while (1-2 months of no problems whatsoever). However in the recent weeks I noticed that after I watched some youtube videos and closed everything, I can no longer do anything except move the mouse and expand the Startup Menu. If I click on any of the programs on the Start Menu or type a program on the Run text box, it won't open anything. I can't open taskmgr, or windows explorer, or even shut down the PC. I don't have anything else running when I'm watching videos except ZoneAlarm and Avast.

The only workaround I can do when this happens is a forced shutdown (holding the power button of my PC), and restart if I wanted to do anything more. But this happens a lot - about 4-5 times a week so I'm worried it would fry up my hardware if I keep on doing this.

I have also tried using either the integrated Google Chrome Flash plugin, or the System plugin for Flash. My Google Chrome and Flash are also up-to-date. – manjivsanotsu Jun 16 '12 at 14:05
    
My first thoughts are: Can you try this in Firefox and Internet Explorer to see if the behavior is the same. That might isolate it to a browser-specific issue. My other thought is: have you run a full antivirus scan and anti-malware scan recently? I'd use MalwareBytes and a second AV such as Nod32 30-day free trial: eset.com/us/download/free-trial. – Paul Jun 16 '12 at 14:17
    
I guess i'll try using firefox for the meantime and respond if i notice the same error. I run a full scan once a week using Avast – manjivsanotsu Jun 16 '12 at 19:34
    
does it ever happen with other programs that may chew up a large amount of RAM? – Steve Rathbone Jun 17 '12 at 2:08
    
It doesnt happen when I'm playing Tropico 4. I tried again last night using Firefox, but it went to BSOD. – manjivsanotsu Jun 17 '12 at 16:08

Did your try to completely uninstall Google Chrome and then re-install it?

There is an article: How to repair my Google Chrome
