nontroppo,I'm sorry if what I'm about to say will confuse you,and goes against what people have just told you....but here goes.. Windows9x(which is Win95,98,98SE,and WinME)DOES NOT manage or handel installed memory over about 256mb(what you now have).Adding more memory is not going to do a thing for you,right now. If your looking to do upgrades on your present computer,I would say to upgrade to Win2000 or XP(that is a full version installe...not the upgrade you put on top of Win98). The new OS will make a big difference,as it takes full advantage of your memory and your chip(the AMD that you have is very good). Your hard drive is small by todays standards...40 or 60 gigs would be much better. After that, if you then need more memory,then go for it. But the truth is you should be able to run Poser without crashes on what you have right now(as I have in the past on Win98SE with ALOT less computer than you have). The thing that I see right off is where you listed your memory...9mg free...thats probably your problem.You've got to much running in the background.Find out what all is running and close them down...when was the last time you defraged your HD(been awhile huh)....DL the little progy called "Rambooster"(cnet or zdnet)as it really helps out Win98 with it's lack of memory management. But one thing to consider after you look at the prices for XP,new HD,etc.....499.00 buys you alot of computer nowdays..plus a monitor..plus XP already installed. SWAMP
