Hi Jennny, Flor has the right idea but! Like myself in the past my tower was ten years and started to "give up the ghost"! Yes resussatation was called for but no joy! Too many upgraded software in a tower which couldn't really take such! Don't know if NCBI can help but they will certainly help you with the recycle and dispose of it for you! Have a look around and you will be pleasantly surprised with what new is around now! Laptops aren't not too expensive now and of course netbooks and if you are going to "splash out" then the iPhone perhaps. Good luck with all that.

Are your computer fans still working properly? there are two. One of them is for the power supply; the other is for the computer itself. Sometimes, in a situation where a fan isn't working properly, either because it's dirty or malfunctioning, to avoid overheating the computer will switch itself off. (They continue to work intermittently, until eventually they stop working mostly, then stop altogether, when things become too hot.) When fans are working correctly, you should feel a breeze blowing through the vents on the back. If that is less than it should be or is non-existent then it's time to get it cleaned or a new fan. Your computer shop will be able to check it out. ----- Original Message ----- From: "janeobrien" <jeobrien5@xxxxxxxxxx> To: "vip students" <vip_students@xxxxxxxxxxxxx> Sent: Friday, November 19, 2010 4:24 PM Subject: [vip_students] computer freezing > hi to the list, > can anyone help me please, > when i turn on my computer everything is in order until i read a > couple of emails and bingo my computer freezes for no good reason. > i turn it off from the tower, but each time i turn it back on i just > get a buzzing sound and nothing happens, this occurs at least 4-5 > times and then it works perfectly. > as you can imagine it is very frustrating. > i am using "jaws 9" and "windows xp home addition" i also have avast 5 > which updates each day. > any thoughts would be much appreciated but could i ask any > explanations in simple language as i am certainly not a computer buff. > thanks for any help. > > jenny o'brien. > >
