Ok' ive been having HUGE problems with itunes on my Microsoft Windows Xp laptop. It worked perfectly fine for years until last Tuesday. While listening to music through itunes on my laptop at work it suddenly and unexpecetly started "screaming" at me with a very high pitched and repetitive noise locking out my laptop. I couldn't close anything, which in turn forced me to having to hold down the power button to force the laptop to shutdown. I turned it back on and let it do its thing, nothing abnormal appeared and it booted as normal. Waited for everything to finish loading etc before double clicking itunes again to carry on listening to my music. Yet this time instead of itunes loading it just simply crashed my laptop.....no error message, no hard drive access light flashing, nothing. Mouse was responsive in moving but I was un able to open or click on anything. So I yet again had to do a hard shutdown. It kept doing it so I checked the internet and itunes own support and did everything it suggested from deleting plugins, to uninstalling itunes and quicktime and re-installing them (upto 3 times). Using msconfig to try (with my limited knowledge) see if it was indeed conflicting with anything and even with just loading itunes and qttask it still wouldn't open and crashed my laptop. I am unsure as to why the fault has suddenly appeared now, nothing new has been installed on my laptop for a long time, with the exception of updates for firefox, windows, norton and itunes, as I only use it to surf the net and listen to music. When it crashes I can move the mouse cursor, but not click anything, back ground programms still run perfectly fine such as a DVD - yes I tried that as I wanted to rule everything out. The original noise my laptop made when it originally crashed has puzzled me and wonder if that is notification of a fault or something to look into, im just not sure what. Overall the lack of being able to use itunes and not fix this problem has been driving me insane for a week and i'm in need of someone's help so if possible can anyone please help me out? Thank you.
