If you put the old drive back in do things speed up again? It is possible that you moved soemthing during the HDD install.

Mobo make & model:
Proc model & speed:
Ram Speed & amount:
HDD Brand & RPM:
PSU Wattage:

Is the computer slow at boot? Slow at loading programs? Just generally sucking? And what kind of difference are we talking about? Just lagging a bit? Or literally taking seconds longer to do similar tasks as the old drive?

we need system specs to help further. This is not a normal problem, please let us know the hardware you are running so that we can help you.

It could be a 5400RPM disk which would make it noticeably slower IMO.

5400 would be notably slower, but not so much that you would think something is wrong. It is more likely a bad HDD, a slow/bad controller, something formatted with the wrong sector size, a jumper setting, a bad cable, or any number of things. But knowing what their hardware config is could point us in the right direction at least.

1GB ram and Win 7 (other than starter edition) is probably your problem!
