My Fedora 7 system is running well, except for the nasty habit of freezing two or three times per day when I am working. First: all windows stop responding to the mouse and key board, then soon after, the mouse freezes as well.
Have you successfully run other Linux disties on this hardware? Try, e.g. Ubunutu 7.04, from a live CD.
A few more things to try....
Try using different applications. Use Konqueror instead of Firefox, etc.
Run memtest86 overnight. If that locks up, you probably have a motherboard or RAM problem.
Set up an SSH log-in for the system, and have that running. Then when the display locks up, if the system is still active, it's probably a video driver issue. top, ps, /var/log/messages and other tools may give you some hints. Then, can you gracefully shut X down?
From what I see here, I think filing a bug is premature. You don't yet know the component to file against, and without a definite cause a bug report is not very useful.
