"I also just recently reformatted my computer so there can't be a virus."
Since no OS was mentioned as well as what protection you used, it's worth noting that XP without service packs, antivirus and a firewall will be infected with a common worm within seconds of connecting to the internet.
The days of being able to do without said patches, antivirus and firewalls are long gone.
For some odd reason, my CPU Usage (found in task manager) is always on 100% when I am on the internet looking at pages that have lots of animations and flash, such as www.cnet.com . This causes everything to be very laggy and slow. My internet is quite fast - 6000Kbps Down and 768 Kbps Up. I also just recently reformatted my computer so there can't be a virus. Could it be a problem with the BIOS? I have the latest version. Should I downgrade a version? What could be the problem? Please help!!
