99% of most laptop problems are caused by your CPU cooling fans (these are the metal thingees that are next to your CPU) being blocked by dust. Most of the time, 6 months of everyday use will cause enough dust to collect in your cooling fans, which will either make your laptop run really slow or simply freeze up.
When dust collects in your cooling fans, your CPU fan will no longer work with you but actually against you, building heat on your laptop’s CPU, causing all kinds of havoc among frozen screens and boot up problems.
But don’t worry, it’s very easy to fix the problem, you simply usually need a screwdriver and carefully locate where the CPU cooling fans are. Simply take all the dust out and your laptop will be running good as new.
The reason I post this today is because my Dell 1525 laptop had the problem of making weird fan noises and freezing up after 9 months of constant use.
Here’s a video on how to clean out the fans for a Dell 1525 laptop. You should be able to find a YouTube video by googling “MyLaptop clean CPU fan”.
P.S. You can also find various free software that will show you the actual CPU temperature so you know when you need to clean your CPU fans.
If you don’t want to do it yourself, simply send it to a computer repair shop but I assure you, they will charge you a lot more for the simple job.
