My computer is on a lot and I’m a casual housekeeper. So I clean the computer fans once a year — and today was the day. I’ve used the same mid-tower case for almost 16 years – started life as a Micron Pentium 90 in 2001. It has been rebuilt at least 2 times with nothing original remaining. And I’m thinking it is time gain. I want a new power supply, motherboard with USB 3.0 capability, more memory and a solid state HD. Time to do a little shopping . . .
