Hi Linda!
A QUAD core? Like in a core 2 quad?
THAT is more than enough processor. Sounds like you may be hung up with RAM if you have only one GB.
Can your system expand to at least 2 GB?
That would be a huge help for you and RAM is fairly cheap.
I can help you with that or tell you how to put it in and show you the best prices for it.
All I need to know is WHAT computer model and make you have.
Thanks,
micro...
