I have heard that some older operating systems had the ability to dump the system memory while still running as an alternative to restarting the computer. Someone I know told me that where he used to work, he had computers there that would literally stay on for years on end and never have to be restarted. I believe he said that the os he used was os/2 perhaps. Does anyone know if there is anyway to do this now on Windows 7, or Ubuntu 10.10? PS. I don't really need to use this in fact, I usually shut down my computer when I'm not using it. I just thought that this would be a way to speed up my computer a bit after using it for a while.
