Lol, don't worry.
Firstly, the memory you showed me is a single stick of 2gb, this won't fit because your motherboard doesn't support it. You need two chips of 1GB each. Also, that memory is 800MHz, your PC supports a maximum of 533. That wouldn't be a problem buying memory thats too fast, but its a bit over-kill... theres just no point spending more money buying faster stuff because you wont get any more out of it. (Something like this:
Computer hardware and software at amazing prices, available online from Scan Computers UK would be good, but i'm, gueissing you already have 1gb or ram in there... if thats at 533MHz though, its just a waste of money buying two sticks of it, since you already have one)
I typed in your computer model number into the Packard Bell website, it told me all about your hardware. I did originally search for your motherboard but this didn't come up with much.
I have never heard of Belarc Advisor to be honest with you.
I know your PC supports that RAM because the Packard Bell website told me
In the future just remember you can get 2 X 1GB @ 533MHz tops, or if you have a new PC, find the motherboard make and model, go onto the motherboard manufacuters website, find the page for your model, and see what the specs are under memeory, it should tell you what it supports.
I'm unsure what memeory you are running.... By right cliking on "Computer" in Vista it should tell you the amount of RAM, but probably not the speed... But its kinda midnight and I've had a few beers so I can't think of a way to know the speed of RAM you have at the moment... I'll post back tommorow.
Don't buy that RAM just yet... I'll help you find out what memory you have
and see what you need tommorow when im a bit more sober... I might save you a tenner.
night...
