My DS, age 14, has managed to convince me that he could build his own computer, with a little help from his geeky friends, as apparently 2 of them did it before. That was really tempting as buying the components separately was saving a significant amount of money. So I agreed and bought all the components from various online places, his friends did indeed provide a comprehensive list with all the links etc. They are now 3 hours into building the bloody thing and guess what? They are at sea and it is not switching on, loads of loose wires coming out of a box. They are trying hard to understand what is going on TBH, watching YouTube video tutorials etc, but I thought I should find out what to do in case they don't manage it IYSWIM. We are in west London, any engineers out there that could come home and have a look at this? How much would they charge? Thanks
