I have a Toshiba 3300M Equium computer, and have had it for quite some time and its still working reasonably well. I am getting a lot of "not responding" error messages when I am trying to download programmes, and it also freezes up as well on occasions.Can someone identify what the problem may be and what I may have to do to resolve it. I have already run a check on the system and there are a few things that need attention, but these error messages make it even more confusing.
This behaviour is often caused by memory problems. Follow the advice from howard64, but also, if you have more than one stick of memory, try with just one of them. You Haven't told us much about the computer or what operating system you are using, but if the computer as it's original build and only has 128M of memory, then if you are running Windows XP it will be running out of memory and that would almost certainly give the problems you have described. Another possibility is that the hard drive might be getting full, and this would cause the same type of problem.
