I've tried the memory and it doesn't work, I think you have to install the memory in pairs so I'm replacing the

• Corsair 1GB DDR2 533 MHz 128mx64 Non-ecc 240 Dimm Unbuffered Cl4

for

• Kingston ValueRAM's KVR533D2N4K2/1G is a kit of two 64M x 64-bit (512MB) DDR533 CL4 SDRAM (Synchronous DRAM) memory modules. Total kit capacity is 1GB. The components on each module include eight 64M x 8-bit (16M x 8-bit x 4 Bank) DDR533 SDRAM in FBGA packages. Each 240-pin DIMM uses gold contact fingers and requires +1.8V.

Or something like that anyway, I'll you know how I get on. Still having trouble installing visual studio 5 on Vista platform, I've tried a number of patches and nothing seemed to have worked. I've going to uninstall VS5 and try again.
