HELP

I am running a system on XP and have to issues, more or less on hardware.

I have SD-Ram in my computer and i want to know if i can replace it with DDR or if i have to get SD Ram for it. I want to upgrade it from the 512 SD i have now. What should I do?

Secondly, I have a playstation 2, video card with an S.Video connection and my computer monitor and I want to play my PS2 on the comp. monitor. I have limited room in my dorm and need a way to do this. I have been told it is possible but HOW!?

thanks

Motherboard = Intel 845WN

If im not mistaken, SDRam is the same thing as DDR but I could be wrong, find out if your motherboard memory slot support what memory stick your about to by, size, latency ect. [edit] your mobo can support up to 1.5 gb so 512 mb is ok

im not sure if you can play ur ps2 on the comp because if i remember that svideo slot on ur videocard is output only..
