I have a PC that is a few years old, it definitely is not the strongest PC but has been very reliable and I've seen slower. Right now it is running way too loud. The fan is at full speed, and it used to slow down but now it runs constantly. I keep all my computers clean, Avira, malwarebytes, etc. I watch what i download, but Windows has so many processes running that I feel it slows the computer down...I've cleaned the computer out, dust all that stuff, I have two other newer computers but I'm trying to keep this one alive so I can give it to my niece..Any ideas?? Thanx to anyone who can assist me.
