Laptops get dirty, too! I always clean the old thermal paste on the CPU and heatsink and then apply Arctic Silver when I clean up and tune up a PC. I blow out the power supply and make sure the CPU cooling fans and heatsink is clean with no dust bunnies. Many times, I ;ll replace the fans and that will quiet things down a bit.

Everyone I know keeps their PC's for at least 5 years... They don't replace them until they fail. I'm constantly upgrading our PC's. I just replaced the hard drive with an SSD in my PC and my wife's PC... made a huge difference!

We have a server in the basement (10TB), so we store all data on the server, not on the individual PC's, so that really helps!
