Why can't I install both sticks of RAM?

I apologize in advance if this is supposed to go in the computer thread, but I was afraid it might get lost in there and this is semi-urgent.
My neighbor has asked me to do a few things to his computer, one of which is installing a 1gb stick of RAM. His computer is fairly new (Acer T180 AST180-UD400B), he said he purchased it last may. The stick of RAM he purchased is a Super Talent 1GB DDR2-800 PC6400 with a blue casing around it.
The problem is when I insert the RAM, one of two things happens depending on which slot I place the stick in. Either the computer beeps at me (one beep) OR the computer starts up but the screen is fuzzy.
The mother board has four slots. The two closest to the heatsink (on the left side if computer is topside up) are purple and the two furthest (on the right) are orange. The users guide is worthless for what it means or what order it's supposed to go in.
I can get it to work with the new stick of RAM (although when I checked the system profile said it had only ~700mb of memory) or the old one (the stock memory a GDDR2-567 512MB 64MX8). Does the G make a difference and make them incompatible? My neighbor says this RAM was the RAM suggested for his machine.
Thanks!

I guess I'm just guessing at this point, but it doesn't sound all too compatible to me. What is the speed of the stock RAM?
This all sounds strange in general.

the orange and the purple are different channels. If you put RAM of different speeds in the same channel it fucks your shit up.
I have no idea why the screen would be fuzzy due to anything RAM related. That doesn't make sense to me. Make sure you didn't break his video card.
I'm not sure if DDR3 and DDR2 get along well or regular DDR and DDR2... I haven't built a computer in ages. Sorry.
Edit: Oh, and the beep probably just means that the system memory has changed. Specific beeps mean different things for different Mobo manufacturers (afaik) but generally a lot of beeping on start up is bad. If you boot it up and it beeps and says No System Memory or something like that then you might have a dead stick or something incompatible with your mobo/paired RAM
The monitor works fine with one or the other stick in.
But it could also be the RAM is not the same speed.... Looks like you've got PC800 and PC533 (Though for some reason is says 567 which doesn't seem right) Normally the Acer cheap out on the intenral parts so who kows..... Its possible the board is down clocking the RAM properly, or the RAM itself doesn't downclock to the slower speed either....
Beyond that, without trying the same two sticks in antoher machine, I dunno what to say...

Maybe the individual sticks of RAM have good karma, yet together plot only destruction. I still can't wrap my head around it...
How can the RAM be bad if they both work individually though?
Also, good call on the try the same two sticks in another machine, I'll give that a try later.
I'm still having trouble getting both sticks in... trying to install the new video card drivers now... maybe that will work.
