Additional 256MB RAM plugged in.

My brother gave me a 256MB RAM today. I just finished installing it. At first I thought that there's a problem with the card because the system did not detect the additional memory. It was still reading the old RAM size when i went to the "My Computer>>Properties". I then opened the CPU again and unplugged the card. I used a bond paper to clean the pins just in any case there's corrosion already. When I tried to install it the second time, I realized I wasn't doing it right. I did not plug it all the way in the slot the last time that's why it was not detected. I had difficulty pushing the card in the slot and locking it, but I managed to do it. Now the system is reading the additional memory.

I know a little about computers, maybe enough to manage adding software and hardware and a little troubleshooting when something's not working. But, I was used to not doing it myself because my hubby does this sorts of stuff for me. Now I have to do it on my own. I miss my husband a lot but having to do these sorts of things by myself encourages me that there's a lot more things to learn.

P.S. I hope I don't have to do this a lot because of problems though... but, upgrades. :-)
