While I'm in the computer room...
My server packed up last week... the thing was full of cat hair and overheated... I took it apart and cleaned all the shite out but it never werked again.

However, I bought a cheap new motherboard to replace it and stuffed 4Gbytes of RAM in it. I'm running XP Professional 64-bit on the board so it can use all the memory.
Anyhoo... using the same Pentium D processor, discs, etc. the new system is significantly faster than the old one which had only 2Gbytes of RAM.
Ipso facto, I suspect that my proposal to upgrade from XP to Windows 7 64-bit with oodles of (cheap) RAM is sound.
My case rests.
