I do think you should get a new computer..... both of you You can really pick up a simple laptop for less the 300 even.... I'm guessing you don't need it for anything other then emails and looking on the web....
You should put the recovery disc into your copmuter, which wipes everything off... then reset everything from scratch..... and make sure you have Norton antivirus or something on your computer too!!! Or maybe your internet is too slow too!!!!
The voice recording would be great for you I think!!!! You could manage in chat with a faster computer....
