not sure if I can help but did you check the MD5SUM (https://help.ubuntu.com/community/HowToMD5SUM) ?

Or has this been a number of downloads already ? Is this only happening on install or is this happening on the boot of the live cd/usb? I know nothing about wubi So I wont try and touch that.

on firts glance your ocmputer seems to be compatible. if download is ok and you checked the md5sunm as suggested then you migth want to try another boot from usb or CD/DVD but this time use one of the boot options. https://help.ubuntu.com/community/BootOptions

particulary the nomodeset option.

post back if you managed to boot.
