I would agree but I have been unlucky with two "specialist computer expert" corner shops. The first could not revive a laptop after I had stupidly accidentally deleted the HDD driver, (yes, I know). I simply down-loaded a generic HDD driver onto a floppy and got the machine going again.
The second guy claimed he was a software expert and had worked on Government computer systems, but he could not revive another machine that had also lost contact with its HDD, (yes, really, I know). He kept my machine for literally months, but could not fix it and was no use at all. But luckily the good folk on the Pprune computer forum helped me there. (And it was a very very simple fix as it happened, involving only about four clicks of the mouse, so very surprised that the computer "expert" could not suss it).
