I have a laptop and the operating system is Vista. I have never had any problems with it. In fact I get far less problems. My daughter has Vista on her machine and it works great. So many people are blaming Vista and sometimes I think that is unfair.

I would have thought that the only responsibility PC World have, is that all components work properly and that Vista and any other programs that they install, work properly. Once you start installing your own software, you have moved on and they do not need to support you for your own software.

Recently I was asked to help somebody who had just bought a laptop with Vista on. He couldn't send e-mails or receive them, and of course Vista was taking the blame. It was a Toshiba laptop and PC World had conned him into buying Norton. I went back to PC World and they refused to give the guy the money back for misselling him Norton. So I just said to the manger, that they had lost my business. The manger didn't seem to care. The machine I bought recently for my daughter was over a £1000. I bought it from Mesh. Did she win. I think not.
Anyway, I stripped the machine of Norton and installed the free version of AVG and NoAdware. Things improved dramatically. However there was still a problem with E-mail. PC World refused to help and told me to get in touch with Toshiba. I did that and had the problem escalated until I got a really good techie. He solved the problem. Some of theses PC manufacturers put their own versions of Vista on (OEM - I thin k that's what they call it), and because of that, a problem was occurring. Once that was addressed, everything was fine.

I suggest you look at each problem, and document each problem. Then join this website forum and start a thread for the first problem and wait patiently and I am sure you will get it solved. Once done, move on to the next question, until you have solved them. Make sure you post in the correct section, as there are Guru's for each type of issue. and surprise surprise, the website is is supported by TechGuy with people who have a vast amount of experience who support for nowt.
The website is Tech Support Guy. Be clear and precise and don't get ratty with these guys as they help out of the kindness of their heart.
