Hi Harriet, It looks like your memory transplant was successful, based on the fact that it boots and reports the proper amount of memory. The first time you booted and got the 'F1'/'F2' message is normal, the BIOS detected a change in configuration and wanted you to enter setup so it could record the change. It doesn't seem likely that the change in memory would have anything to do with firefox not working properly. It is more likely that there is an issue with your network connection (how do you connect to the network? Did you send this email using the same computer?). Is it possible the network connection was disturbed when you installed the memory? Also, I am not sure about firefox (I don't really use it), but in IE, it can be set to work "offline", if set this way, you would probably get the symptoms you describe. Have you tried starting IE to see if it works?

I got out of it - shut down - then thinking it would let me start that over again so I could click on F1..... not so... it took me to my desktop. Now, my Firefox is not working right like it did before I did this. I uninstalled it and reinstalled it. But it's still not the same. Could this be cause I bought 2 GB of memory instead of what originally came in here which I had this Processor.......................Pentium 4 CPU 3.00GHz Processor Speed..............2.92 GHz Memory (RAM)..............2048 MB Operating System............MS Win XP Home Edition Operating System Version...5.1.2600 Not sure if that Ram is right with what I had.... but this is what shows now. What I'm trying to ask is, since I did not put the exact same thing in here as I had, would this make my Firefox mess up - what I mean by messing up is... when I put a link in the address bar, it will either say 'can't be found' or something like that. It does this quite frequently. Harriet **************Start the year off right.
