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.
