The OP has disappeared so we're not able to discern what is problem
without him posting more info.
I note you are a virginmedia poster, the easiest and most reliable way
to ensure one buys the right modules for one's PC is to use crucial's
online scanner:
http://www.crucial.com/uk/?gclid=CNT...FRpgMAod6BywsQ
Crucial are also the cheapest (in UK at least) for memory upgrades.
Alternatively, if anyone is relunctant to buy online or knows of cheaper
elsewhere, they could download Belarc Advisor:

This will perform a full audit of a computer, it will tell you type and
capacity etc, but also tell you everything about a PC, from OS key,
hardware, software, drivers, versions, hotfixes, patches, etc etc.
