I powered it down, and I opened it back up, took out one stick, and put in the original 256MB stick. It booted. Somewhat faster than before, I could tell. I looked at CPUZ and it was able to recognize the extra ram.
After that, I powered down again, opened, replaced the 256MB stick with the 512MB. It did that black screen and three long beeps.... OKAY, I'm mad now... Lol. I did switch the sticks (512MB) to check if it was one of them was broken or something... they were not. So after pulling out one of the new sticks and replacing it with the old one. I went into the BIOS, and I looked around at the Advanced Settings. I changed some of the SDRAM settings from "100MHz" to "Auto".
It still did the black screen with three beeps..........
EDIT: Further inspections...
I took out the 256MB stick, and just left the 512MB Stick, and it looks like it won't turn on with out the PC2100.
I'm guessing that the new PC3200 Sticks will not work without the PC2100 stick to copy it's speed from, so in that case, I believe I must return the two sticks for 1GB of 2100-3200 and input that with the 256MB.
Am I right? or is there some other possibility?
