Yes, Kate, it sounds like you need someone to look at your computer or motherboard. I'm sure you checked to see if the motherboard can handle all the memory you gave it? I recently had a problem with my motherboard or memory. My old 64MB SDRAM died.. I kept getting beep beep beep when I booted up. I removed the SDRAM, and the beep went away. That was a good excuse to replace that stick with another 256 MB SDRAM. That brought my old Intel Celeron board to the max. I've been inspired to backup my entire Poser Folder.. everything. I'm doing that because some stuff gets installed outside the Runtime folder. I have about 10GB of stuff, and it will take 12 CD's to backup. I've had 30GB installations before. This is an older CD writer, so we're looking at the better part of the day off my computer while the job is done. I'm suffering badly from a cold so it's a good excuse to go downstairs and watch the Lara Croft Tomb Raiders movie I bought. Wooo.
