I do not like Dells. : I They always cause problems. : / HP is just as bad, they both give me a bad taste in my mouth. I worked on a computer once for a friend of my Dad's, it was a Dell, and the power supply was some no-name 160 watt Chinese power supply! Which promptly died, since it was trying to supply over 250 watts of parts...
Anyway, do you have any problems like this with other software? I'd assume not, but it's always a good idea to ask. The non-standard amount of RAM that you have (2.5GB) has me interested, since that's a rare setup.
