I need help again-.-

As you might be able to tell I'm not the best computer person. My windows 7 laptop (dell inspiron n5050) was running really slow to the point nothing would open and my computer would be frozen. I tried around 7 anti virus programs and cleaned out the registry and defraged the HDD but nothing worked so I wiped everything and did a factory restore and I have the same problem. I know the internet is full of answers but I wanted to hear them from the people that I believe are the best computer technicians on the web haha

I feel like I should also say the Linux partition I just made works perfectly fine but windows still sucks.
