When I found out that my hard drive was dead I wondered if I might have to buy a new PC. As that would have been a costly exercise I decided to try a new hard drive first.
I dismantled the old one and took the hard drive round to the shop to ask about a replacement. Fortunately I found a shop assistant who recommended the right kind of equipment.
I also asked about the old PCs microchip´s cooler fan and learnt that the thermal conductivity compound linking the chip to the cooler should also be replaced after a few years as it would have dried up. So I bought some thermal compound as well.
Back home I unplugged the power cable and removed the cooler fan from the microchip. I then applied the thermal conductivity paste and put the fan back. By the way that is perhaps not always an easy task as you are working in a very confined space.
Once everything had been put back together again I switched the machine on and installed the new operating system and the software tools I would need. So here I am back on the internet with a “new” PC at a fraction of the cost a brand new one would have cost me.
