PP7 computer speak is gobbledigook to me, magnetic media, bootloader etc is a foreign language to me........ I have a computer guy who is very good, when I have problems he fixes them, he comes to my place, he is very good and very reasonable price wise,
I haven't needed him for a couple of years now but actually I just called him today, my PC is freezing up, it only lasts for about 30 seconds or so and only happens a couple of times a day and at present it ain't really a problem.......but I like to pre empt any problems, don't want it happening when trying to place a bet where time is of the essence, but I digress,
What area do you live? I could give you his Number but he only works the south coast around Kiama, not only is he reasonable price wise and not only is he good computer wise.....he is also honest, what he tells you will be the cheapest way to go, he has been my computer guy for quite a few years now and I could not recommend him highly enough
I have always found you don't have to know anything about anything to succeed in life, so long as you can source out those that do and use someone else's expertise, I do what I do best and let others do the rest at what they do best!
and always remember....CASH is King!
Hope it all works out for you, my PC is like a family member(well not a close family member) but I would be devastated if anything happened to her
Good Luck and good punting
