Computer Hangging

My computer always hang half way. I don't know the cause. Can anyone help me?

 

Be more specific;on boot,apps,what?

 

The whole thing... But mostly when I'm using Internet Explorer.

 

Do you check the drivers in device manager.Do you scan comp from viruses and spywares.Try to clean your comp with CCleaner.

 

It's not a guarantee but i find i have that problem when the number of temporary files build up try a good clean out.

 

Fix the issues in CCleaner also.

 

It's alright now. When I've installed Zone Alarm Firewall. It doesn't hang anymore.

 

Not sure why installing Zone Alarm would help this issue.
You may still want to do a little maintenance.
Run all apps everyone suggested:
Ccleaner- run the cleaner and also have it fix issues.
Defragment your hard drive
Allow your anti-virus software check your system
Run the freeware version of Rogue Remover

 

Yes, yes. I've done all of the above except that Rogue Remover. But I'll try it as well. Thank you!
