Greetings all, hopefully I can find an answer to my problem here.

I am fairly new to this, but I did have a fully working 10.4.8 install going for a couple weeks with no issues, and decided to try 10.5.2

The install went through with no problems at all on a fresh partition. Everything seems to work fine once I boot up, but I am constantly getting the multi-language "You must restart your computer" screen of death. The computer will be running fine for anywhere from 5-30 minutes before the crash happens, but it happens every time.

Specs:
eVGA 133-K8-NF41-AX (Nforce4)
Athlon 3700+
eVGA GeForce 7800 GT
1.5GB PC3200
Onboard LAN
Not sure what other specs would be necessary to know...

I tried with the 9.2.0 kernel first, then formatted, reinstalled with the 9.1.0 kernel and am having the same issues.

If anyone has any ideas I would appreciate it!

turn off your nforce lan in bios and see what happens then.

Do as lanxxx says, I had a similar problem with nvidia lan, and system would restart, do indeed disable that and try to use a dedicated ethernet/wireless card.

I'll give that a shot, thanks guys.

Hmm...I have been having the same problem too. I guess I will try a different network card too. But is there no fix for this at all? Rather than buying a new card?

I just got same problem with new 10.5.2 Rev.2
Boot on dvd and after some minutes trying to load shows up this screen.
Rev.1 works well, i have installed many versions before and never had problems like that. :(

If you are running more than one harddrive, you might wanna try to disable Spotlight on all drives except the OS X one.
I never had this problem myself but I read somewhere (on the insanleymac forums) that this might help.

Worth a shot maybe.

No, i disable the power of other drive and same problem.
