I think I paid all of $20 for the additional memory .. Dangerous Dan's hourly charge was the "big" ticket item, and it would have been the same regardless of how much memory he put in, as he was also evaluating/updating all the software drivers, and verifying that there were no residual Trojans or keyloggers or backdoors in the mix .... so I basically got a brand-new CLEAN computer for under $100 ... and I think he put in a dual-boot system so it's possible I have a 64 bit processor also though I don't think XP supports such
dual-boot systems have nothing to do with 64bit. Dual-boot means that when you boot up you choose from a list of two or more operation systems to boot the computer into.
goes to show you that I know just enough about computers to be dangerous, so instead I simply tell Dangerous Dan what I want to do with the computer, and he, who speaketh computer as his first language, (and is nearly impossible to understand when he talks what he THINKS is standard English), puts in or modifies what he knows will do the job I want to do
