You could also try using Blind write suite from VSO. CDRWin is usually pretty reliable but some games have sub channel data and CDRWin doesn't read the entire sub channel. Blind read ( part of blind write suite) reads whole sub channel and can also make a CDRWIN compatible image incase you need to patch the image. Then use blind write to burn the image onto CD
As for why your computer hangs, this could be a million and one reasons. two common ones are having the CD reader and writer on the same IDE bus. Try having reader on IDE 0 and writer on IDE 1. Another is two copy programs clashing with each other. Try removing all other cd burning software temporarily and seeing if CDRWin works then. You didn't mention if a simulated burn works or not. If simulated burn works then it could be the brand of CDR you are using. Could also be that the version of CDRWIN is not 100% compatible with your writer. Hope this helps.
