You've formatted your computer, reinstalled the operating system but still no go!!!Your PC continues to respond slowly and freezes at times . Well in such cases its not an issue with your software but your hardware . As time goes by your CPU would definetly have a lot of dust particles in it which starts collecting in the heat sink of the CPU . This blocks the gap between the CPU and the CPU fan thus preventing flow of air and hence the CPU temperature increases , which inturn reduces CPU performance , which inturn slows down your system making it slow to respond and also could freeze it at times . So the solution here is to clean your CPU including the Heat Sink . So here's how you do it :
WARNING : I do not recommend this to those who havent opened up the cabinet before and who havent seen whats actually inside a pc . THis is because the CPU is the last area you would want to play with . As any silly mistake like not placing the CPU fan back properly could lead to a burnt CPU . So please be very very careful!!
Note : This process can be done once a year . As a lot of dust collects in the heat sink area during a period of 1 year.Also this is something that i have done and tried with my machine which has yielded positive results . It may or may not be the same for you as you may have a different configuration!!
Step 1 : Shutdown Your Computer , Disconnect it From the Power cable and leave it idle for a while (like 10 minutes ) for the CPU to cool
Step 2 : Now Remove the casing of the cabinet
Step 3 : You should see the CPU fan at the center of your motherboard.
Step 4 : Unscrew the CPU fan.
Step 5 : Now you should see the heat sink and most of the dust particles which is probably collected.I had a lot of dust particles collected in my CPU heat sink.
Step 6 : Here i used a vaccum cleaner , mine came with two outlets , one which would suck up air and the other which would blow air.
Step 7 : I first used the outlet which sucked up air and removed all the dust particles which were light and remained on the surface of the heat sink
Step 8 : i think used the other outlet to blow air into the CPU which removed all the major dust particles from the heat sink . By now most of the dust particles were removed , but there were still some heavy dust particles which still had to be removed.
Step 9 : For this i used forceps , something like your divider in your geometry box or thin small scissors.
Step 10 : This removed all of the dust particles.I had a lot of dust particles collected. Here's how much i removed at the end of it.
Step 11 : Then insert back the CPU fan on the heat sink ( ensure that the fan is fixed back well)
Step 12 : Do a final cleaning similar to step 7 and step 8. Ensure that no other component in your cabinet has any dust particles!!
Step 13 : Close the case of the cabinet .
Step 14 : Fire up your Machine.
This helped me a lot and it not only improved system performance but also reduced the CPU temperature by almost 10 degrees . Here's how you can check CPU temperature in linux . Hope this helps you as well!!Happy cleaning!!!
