Yes, I know I'm probably throwing away the bucks and a new eMachines I can get for four bills, but I guess I'm just stubborn! 
eMachines is actually Compaq now, isn't it? I was warned off those by a guy who has a closet full of Compaq junque.
Well, if you think it won't do much harm to install the PCI card, I guess I could try it. Only thing is, when I put the second of the 17 inch monitors on, there wasn't a driver in Win98 for it (Envison), and it made a squealing noise while it was operating--likely on the wrong refresh rate--with a 15 inch monitor driver that Win98 loaded. I guess the newer OS's don't have that quirk any more.
I'm just wondering about the proceedure--I know it's all plug n' play, but I'm thinking I'd still have to disable the old card somehow, perhaps in the BIOS.
See, I'd like to keep this computer to do minimal internet stuff with, and when I get a new one, I'd use that mainly for creativity. No sense spending all that loot if I'm gonna make it vulnerable to internet attacks, blah blah. (Yes, I've got full protection on the old one, Firewall, Anti-virus, Anti-spyware,etc.)
Are we having fun yet? Well, I get your point, and yeah, this thing has been a headache big time, but i'm willing to tough it out untill I get it stabilized.
