So I have ASUS RAMPAGE II GENE MOBO on my computer. This MOBO has on board RAID. I have a RAID 5 setup on three of my HDD drives and a RAID 0 setup on my two SSD's which I use as my boot. Recently I have noticed a problem: If I leave the computer idle for an extended period of time(I haven't been able to narrow down the time period) the computer freezes up and I need to reboot the computer to get it working again. I think I've narrowed down the problem to the RAID setup as I have noticed that if I am verifying the RAID integrity of the RAID 5 setup the computer will not freeze up so long as the verification is in progress. This work around suits me at this present time so its not a huge problem.Also, It never freezes up while in game. I'm would like to know what causes this though. Is it just that an on-MOBO RAID setup always sucks? Is it likely that there is something wrong with my setup? If anyone has any insight as to why this would happen I would very much appreciate it.
