I was talking in general terms. Your machine is 4 years old, but 4 years ago the common amount of memory used was 256/512 MB. of RAM and your machine have 1,5 GB. of RAM right now.
Maybe you have upgraded your RAM, but that helps Windows 7 a lot. Also, a K8 motherboard with an oldie 64 bits processor is not something that we can call an OLD computer.
Also, all we know that new Windows editions needs more RAM than processor or motherboard chipset's power. So, you can have a great motherboard with a dual-core processor, but if you doesn't have enough RAM, then the HDD will start to scratch just after every double-click you do.
