Why does my computer hit 100% CPU?

I was reading an article online and then in my internet explorer I start getting blank pages going all the way across in new tabs. I hit the CTRL, ALT, DEL and it pops up a box and it will say 100% CPUs. Why does this happen? Why does it take me a long time to shut down the internet explorer when it does this? Why do the pages keep popping up? Thanks so much for your input.

Hey, Do the empty tabs open when you are surfing one specific website? Or do they open randomly 'by their own wish'? If they open automatically, it could be the work of a virus/trojan. I suggest you scan your computer with a good virus scanner, or an online scanner from Kaspersky, etc. Hope i helped

No the tabs will just start opening on thier own. I have scanned my computer and nothing is on the computer.

I do use Spybot. I love it. I also ran a scan for that and did more immunizations and found nothing still. I use avast for my anti-virus ware.

It could be malware or could be your IE is crashing. Try Firefox3. I think its better.

your first response you got is a good answer, now you mentioned that IE is opening a lot of new tabs and what is happening when you sort to see what is causing the 100%cpu usage you will find it to be IE on the process tab just close that item or end it. What happened is you hit a bad site with a loop that just opens a lot of instances of IE or a lot of tabs it just depends on what you have IE set to do.

Hi, There could be many reasons why your CPU is hitting 100% usage. Some of the common things could be viruses or worms which do attack your system when you go online. Some of the quick spot checks for you to do would be: 1) See if you installed any new program. If so, then verify whether the source of this software is virus free. Sometimes the program might be a resource hungry one and might be starting a process in the background that takes 100% CPU. 2) See the task manager to see which process is taking 100% of your CPU and see if it relates to some software that is supposed to be loaded or not. If not, it is a virus. Hope this helps. Cheers! Ram
