You probably accumulated way too many programs, viruses and broke quite a few things on the way. I would recommend you just reinstall, we can't really diagnose the situation given that there are literally thousands of reasons you could be experience a decrease in performance.

Just google your model, you should find all the drivers online

You need to fidn you Windows 7 Installation CD that came with the computerm if you can't find it, get a CD from a store, or online, once you have that, go online again and look up your laptop model number and company, download ALL of the drivers on the website, and save them to a USB or Portable hard drive, re-install oyur windows 7, plug you hard drive in, and then install EVERY SINGLE DRIVER/UPDATE, you need everything the site gives, plus the extras, like Anti-virus, malware cleaners and lot's more.

That's what you need to do at the moment, try those things, and see if it works.

PS: Your windows 7 serial key is located on the bottom of your laptop, if it asks, put it in, if it doesn't ask for a serial, which it might not, that's good, just keep going and it will install normally, and one more little tip, i reccommend just "Repairing" your installation, rather than fully re=installing, this way, you keep your drivers and stuff, because it only re-installs the WINDOWS files, e.g. the file on your local disk "C:/Windows"

Tell meif it works for you ask if you need any more help, or if you need clarification.
