7.04 acer aspire graphic install fails

4 tries at a 7.04 install on the Acer Aspire 5315 failed under the graphic installation procedure.
On a whim, I chose text installation and it was successful. Once 7.04 was up and running with a LAN connection to my DSL, I added upgrades, and was able to download to 8.04 which is working ok. It looks as if some machines are more friendly to the text installer than the graphic one
