Installing 11.2 very slow on my desktop

I’m busy installing 11.2 on my desktop PC which is a Asus M3N78 motherboard with AMD 2 core 5400 processor, 2GB ram and 2 SATA HHDs with 2 USB external drives.

I’ve run a check on the installation media and found no errors. I start the installation and it all goes fine until it gets to the timezone part and then sits there for 10mins with the cursor twirling away. Then each setting and prompt after that takes 5-10mins to proceed to the next step.

Any ideas on what’s going on?

EDIT: It seems to be the hardware probing parts or something because when it actually reads from the DVD it seems to read at normal speed.
