Well, I went to Future Shop to find the RAM I need. I gave them the receipt for the computer I bought. They gave me the RAM they said that should work with the computer I'm using. I tried it but it wouldn't fit. I returned it and they said that they don't know which RAM to give us then.
Operating System: Microsoft XP Home Edition (5.1, Build 2600)
System Manufacturer: HP Pavilion 061
System Model: PS583AA-ABA-a1020n
Processor: Intel(R) Pentium(R) 4 CPU 3.06GHz
Memory: 504MB RAM
Thanks for any help you can give me.
