|Your system is a dead-end for many reasons. For starters, the motherboard is BTX.|
FYI, BTX is a form factor design that Intel came up with several years ago that completely changed the motherboard & case layout. It never caught on & was basically over before it even started. Since you have a BTX case, you would have no choice but to get another BTX board. And just to give you an idea what they're worth, here's a brand new BTX motherboard for $6.50:
"I can only keep 2 IE pages open at a time with this ram"
RAM has nothing to do with it. XP performs decently with 1GB RAM as long as you don't have a bunch of garbage software installed & you practice regular "housekeeping". Or are you saying you only have 512MB with a portion of it being used by the crappy onboard video?
Are you running SP3 & IE8? Do you have IE tweaked for best performance or did you just accept the defaults? For instance, how many days are kept in History & how much disk space is used for History? Do you still have indexing enabled? Do you regularly defrag? Which anti-virus program do you have - McAfee? Norton? They're both resource hogs & will slow the system. Do you have a bunch of programs loading at startup - AIM, iTunes, Yahoo, Google, Microsoft Office, Windows Live, QuickTime, Realplayer, camera/scanner/printer software, etc? None of them need to pre-load, all will slow the system.
