Using build 6801, within 10 to 15 minutes of browsing the web, the system would freeze and needs a hard reset. In addition to the IE8 that came with win 7, I've tried Firefox 3 and the latest Google Chrome all with the same freezing result. And it doesn't happen on the same website. System is a 1GHz Athlon with 1Gb ram. Anyone else come across this and found a solution? Thanks.
