System always freezes after few hours that is on

[raylock]

Hello, I've successfully install snow leopard 10.6.2 on my system:
Gygabyte GA-P55M-UD2
Intel i750 + 4Gb DDR3 1333 7-7-7 OCZ
Nvidia 8800GTS 512Mb

but my pc after 3-4 (sometimes 5-6) hours that is on always freezes no matter what it do (listen music with itunes, download with amule or nothing)

I've tried to disable screen saver, monitor sleep, pc sleep but it always freezes.

I don't know what i can do....

Have you updated the bios to F5?

 

[raylock]

Yes I do, what are your best bios settings?
thanks

Check your console for any suspicious messages right before the freeze happens...

repair permission with kext utility.

Check System Profiler- do your SATA and USB ports show up as Built-In? Like this picture:

If you don't, the DSDT isn't being recognized correctly. Otherwise, I'd download and run Onyx- you may have some permissions/disk issues that need repairing. Run the full Automation process. Good luck!

Hello, thanks to all, good news, I run the onyx system maintenance and now the pc is up for about 12 hours and no freezes at all.
