Inspiron N7010

Hello all,

Over the past few months, my Dell Inspiron N7010 laptop has had extremely slow performance than borders on freezing. Because my internship next week requires a laptop, I'm now attempting to fix this. So far, I've ran MalawareBytes multiple times and nothing has come up of interest. 

Yesterday, I had everything up and running well at normal speeds surprisingly. That being said, once I shut down the slow speeds started up again starting with the "Starting Windows" message at start-up which took almost 5 minutes just to get to the log-on screen. As soon as I got on my account today, I immediately opened Windows Task Manager to see if there was any process that was slowing me down and I've found nothing suspicious. Windows Task Manager is reporting that my CPU Usage is at 0% and Physical Memory at 33%. For example, if I open the Start Menu and type something into the "Search programs and files" search bar it doesn't even come up and the Start Menu seems frozen for almost two minutes. From my knowledge, there were no suspicious programs or files ever downloaded onto this laptop. I mainly only used it for Microsoft Word and schoolwork. 

While I believe this might be a O/S or virus problem, I could be physical. This laptop has always been unnecessarily been prone to overheating. For the amount of money I paid for this, I should be getting a better quality product.

As for the warranty, I doubt that is still intact. I purchased this laptop over a year ago. 

If anyone can help me, that'd be greatly appreciated. If you need any information to help me fix this, I'll gladly provide it. 

Note: I'm using my desktop computer to post this.
