I didn't mention the FIRST thing I did was take the Dell outdoors and blow the TONS of dust and dust bunnies out its interior, the CPU heatsink and the power supply with my power blower...I wouldn't even bring it into my house like it was. The fan may have lasted a little longer if it hadn't been spending its life on a cement warehouse floor!The company I left 4 years ago had Dell PC's that were made in the early 2000's.........hundreds of them all over the plant floor. They all ran on XP.
