lockups + boot problems :/

Great biased statement. That really helped him to figure out his problem considering it worked great until 1-2 weeks ago.

My ati is rock solid and is excellent in all the games that I have played. So I would seriously have to say that if the system is setup right then there should not be any problems at all. Mental you did say it worked great. Maybe there is a setting in the bios or maybe just a good o'l reformat would clear it up.

Mental you mentioned it work great until 1-2 wks ago. Have you did any upgrade on the drivers. If so you might want to try to reinstall all the ati drivers you got and reboot and then install again. But keep digging it will come around
