I am trying to diagnose a random shutdown issue on my HTPC. It will randomly shutdown as if someone pulled the plug on it. It is 100% stable otherwise.

I did have an EVGA Nforce4 SLI board in it which I upgraded from a 3500+ Winchester to a 3800x2 Toledo. That's when the issue started. It also uses Bluetooth wireless for a Microsoft keyboard and mouse through a Microsoft USB Bluetooth dongle (hehe). There is a wireless G card in it, which was a DLink, but now is a Buffalo. It also has one of those super USB reader things in the front for memory cards, etc.

I thought the motherboard was croaking, so I got a new one from Carl. It is the Epox Nforce4 Ultra. I did a basic swap and still had the same exact issue. I started looking deeper into what it could be and tried disabling USB 2.0 and running just 1.1 instead and so far it hasn't had any random shutdowns.

The thing is, I ran the exact system before with the EVGA SLI board and a Manchester 3800x2 with USB 2.0 enabled and had no issues at all. I did not have USB Bluetooth or Wireless G on the board at that time though. I also read about a lot of USB 2.0 issues on Nforce4s, which leads me to believe it is a USB issue more than a compatibility issue.

Right now, it is 100% stable and not randomly shutting down, but I have only USB 1.1 running. I would really like to use 2.0 for the memory card reader. Any help resolving this would be greatly appreciated.

I will try to test it without the Bluetooth dongle (hehe) and without the Wireless G when I find the time.

is the HDD a WD?

my nforce board did that with WD HDD, replaced it for seagate and problem stopped.

The hard drives are 2-WD 160s in RAID0 on Highpoint RocketRAID PCI card. The only onboard drive controller in use is for 1 DVDROM. The RAID card was used in my previous build, but with 2-Maxtor 40s.
