Hello, I know this Dell is rather old but it is all I have for use until I have saved for a new laptop. My problem with it is that it is very slow. It has a 1.8GHz Intel Celeron CPU and 512MB of RAM and it runs Windows XP Home Edition, but when I attempt to browse the web via Google Chrome or Firefox or any browser, it's really slow. Trying to load a video on YouTube on this thing is pretty much impossible. I assumed this was just normal behaviour for a machine this old but I was told by a friend that 512MB should be more than enough to run Windows XP without it being this slow. I constantly get the "virtual memory minimum too low" message while trying to visit Twitter or Facebook or even when checking my mail. I've just tried increasing the virtual memory and I will check if that has made any difference but I'd just like to know if there's anything else that can be done to improve this machine's performance. Thanks in advance for any help.
