Hello,
I think my cpu is overheating but i need some validation from people who know. About 2 weeks ago my fans in my pc would randomly spin extremely fast making a grinding noise for 5 minute intervals. 3 days ago it did it more often and yesterday it does it as soon as i start up my pc and today.It won't stop and my monitor goes to sleep at random times and wont turn back on. My internet is also going out at random times until i replug the cord.

Is there any reason for it to suddenly overheat? my pc has been in the same place the last 5 years and it didn't start this until 2 weeks ago.
