Computer Crashes

My Computer decides to reboot itself zero warning just mid game. Ive checked and its not a heating problem. I get a error report from windows that it says its caused by a device driver. My motherboard is A8N-SLi Deluxe, and I have 4 yellow questionmarks under device manager.
1. Other PCI Bridge Device
2. PCI Memory Controller
3. RAID Controller
4. SM Bus Controller
Im sure one of these is causing the problems and I dont exactly know where I can enable these so hopefully it solves my problem. I could be wrong though...

try the cd that came with your motherboard.

you could also just disable the RAID controller, since you aren't using it.

other 3 should be part of the chipset driver for your nvidia. You can get the latest from nvidia.com. would be considered a Platform driver.

Would anyone have a direct link? Make sure i get the right thing... and i disabled my RAID. TY

A8N-SLI drivers from ASUS:
