No. All motherboards that I know of with more than one memory slot can cater for different size modules to be used at the same time. For best results though, I recommend that identical modules are used, particularly when utilising dual/triple/quad channel memory.

Out of interest, why don't you replace both sticks at the same time?

I am going to build a gaming rig in the next 6 - 12 months so i dont want major upgrades ( i will buy an adapter for some 4 gb laptop ram and install that on a later date. i had this 1gb stored on a non functioning computer so i decided to have a temporary memory boost.

Not a bad card, but I might consider upgrading it when I next upgrade the rest of my system - although this is probably going to be next year.

It's been a while since I've worked with DDR2, but I thought the voltages varied greatly with DDR2, and that could easily cause the issues you are seeing.

What speed is the DDR2 512mb stick? Is it the same as the 1gb stick you have put in (in theory i believe they should still work but they would just run at the slower speed of the 2 if they were different but i have known motherboards to be fussy :( )

DDR2 Speeds Example:
DDR2-400
DDR2-533
DDR2-667
DDR2-800
DDR2-1066

You could also go to Use the Crucial System Scanner software to find out what type of memory is in your computer and run the scanner, it will tell you what memory you would require:

Example:

Run the scanner:
1.png

It will then give you an overview and advise what is compatible on the left:
2.png

It will also give you upgrade options if you click the link on the right that says 'View Quick Configurations'
3.png

This may help determine if the memory you have is compatible or help upgrade in the future.

I hate to rain on the picnic but another 512mb of ram will give you no see-able difference.
