sorry for the late reply dude.. I slept last night and have'nt seen your follow-up question..
1st, you have to back-up all of your files to an external harddrive or if you have a D partition or more, save it there (unless you save your window files in drive D save it on E instead).. do this on your current hardwares (not upgraded yet).. this is to safeguard all your data..
2nd, if all of your upgrades are ready for installation, install it for yourself, or perhaps it's better to ask the technician or sales person where you're buying the upgrades if they can install the hardwares for you.
3rd, switch on the unit. as to my experience, no problem will be encountered, but, theoritically, since there is changes, a system crash may occur. At this time, you have to reinstall your winXP. Boot from the disc. upon completion of loading the files needed for installation, press enter, f8, and then the system will search an existing windows and then press "r" to repair the system. the installer will repair the system for you, no need to identify what specific system file you need to replace. the installer will replace all the system files to adopt and configure it, based on the new environment. with your new specs, repairing would take 30mins - 1 hr.
as you can see, you have to gamble, you have 50-50 chance of zero headache or go to the repairing process. unfortunately, there is no precise or easier method than this.
