Make up your mind.. if you do not stop, you will be banned. Please consider yourself warned.
If you want to know if your computer will run XP, I would suggest starting with the minimum requirements on Microsoft's site.
In the mean time, please don't ask for free things while at the same time talk about buying or building a new higher-end computer. Those are mutually exclusive things - if you have money to buy/build a new higher end computer, then use that money to buy a machine to do both, or buy two new ones that will do the job.
EP, glad to see you come back and tidy up...did want to ask a one day favor, I want to enhance my resume , was hoping you could make me administrator for a day, if so, take me right off since I won't be here to do anything, and don't know the slightest about the board, but it would be nice putting "served administrator osnn", if can do, THANKS
