My computer has started running really slow recently. My instant messengers are contantly freezing and not responding. My Internet exployer hardly even loads anymore, I can't even check my email becasue of how slow it has gotten, makes the web pages freeze. Windows exployer even has started to where it doesn't want to respond either. I really need some help here, it's a new computer and the geek squad at Best Buy tells me there is nothing wrong with it.
