My new PC

Just over a month ago I bought a new PC windows 8.1, 12 GB RAM 2Gb graphics are the basic configurations of the PC.
After 4 days it just refused to start up so after 4 hours I phoned their support number and was told to turn the PC off by the power button then turn it back on still the same I told them, I had already tried it twice before calling them, they told me to call the other number to send it back for repair, I nearly told them it wasn't fit for purpose and I wanted NEW but decided it may be an update glitch and they will install a patch to stop it happening. They did this and replaced the graphics card as well, one of the nodules for the D-SUB connection was missing.
A week later it returned and the first thing I did was turn off automatic updates, all has gone well until I downloaded itunes to stream a pre-release of ROCK OR BUST the latest AC/DC new album. then the machine refused to shut down.
I tried a few things even a download to stop fast start-up but that failed but the actual solution was a very simple one just uninstall itunes  the machine is 64bit so I had installed the 64bit version of itunes.
First I uninstalled all the junk to do with itunes using revo uninstaller then as itunes didn't show I searched for it then uninstalled it then shut down the PC success the PC was now working as it should again.

Sometimes the simple solution is the best answer, in the time I have had this PC it has caused more problems than my last one, windows 7 home, did in nearly 6 years, this PC is no faster than the old one that was a 2.6 Athlon quad core with 1Gb graphics and 4 Gb RAM. I may send it back to the manufacturer for repair and have more RAM installed.

EDIT

I found out why my PC wouldn't shut down properly it's my  USB3 2 Terabyte external hard drive it stops the PC from shutting down since I disconnected it I haven't had the machine not shut down but the 500Gb USB2 works perfectly. I just started fast start up to see if the machine shuts down if it does then I effectively have 2 USB3 ports that are FUBAR.

GIDS again

George Iain Duncan Smith is spouting his crap again, claiming foreign children are filling schools but cannot speak English. The solution is simple if they don't understand English, don't let them attend school and remove all benefits for the child until they can speak and understand English, if they claim discrimination tell them to leave the UK it's that simple.
If they want to live in the UK they should speak English, it is up to the parents if they want to also teach them their native language as well, the UK must stop doing forms in different languages as well, English only, if they don't understand it then they don't claim, SIMPLES.

If only the parents speak English they should teach the children English before they try to come to the UK, personally I would like to see the Australian approach of get the job before you come if you lose it then get another within 2 months or leave, no benefits while they are out of work for 5 years and only 6 months benefits for the next 5 years. 

A family member took in some students who were here to improve their English and they tried to make out they didn't understand anything, that is until their stuff was packed and the office was called and told that if they didn't speak English they could be found somewhere else, they soon started to speak almost perfect English.

Sometimes you just have to be strict all this BS they use now about unfair conduct is just that BS if they won't speak English refuse to have them in the school and report them as not attending when they don't come back the next day.
