Help Needed - New Hard Drive Causing Problems

[double-t]

My aging system is listed below. The OS is installed on the Raid0.
I recently added a new 500gb hard drive to replace an 80gb that was running out of space. The 80gb was (correctly) listed as a master and was working fine, but for some reason the new 500gb is listed as a slave. The problem is that the system is now regularly rebooting.

Nothing else changed. I have plenty of power. The only issue I can thing of could be heat, but that wouldn't change the master/slave setting. There was a little dust kicked up when I changed out the drive, but all appears to be clean now.
I am using round IDE cables, but again, there was no issue with the old hard drive.
The other thing is that I believe the Raid array used to be listed as Ultra DMA mode 6. It's now listed as Mode 5. They are 133 drives.

The new drive is listed as Ultra DMA mode 2. Shouldn't it be Mode 5?

Maybe I should just replace the cables? Sorry for the rambling but I'm not really sure where to turn.

1 maxtor 500gb IDE, 7200rpm (the new drive)

It is getting "overloaded". You may need a new processor, MB, and RAM.

Can I ask what part(s) in particular do you think are getting overloaded?

It is getting "overloaded".

I'm not even quite sure what that means.

Do some basic troubleshooting to try and track down the source of the problem. Try: manually setting master on the new drive, replacing the cable, unplugging all drives and moving to a different channel, plugging the hd into a different system if possible, see if there is a bios update for your mobo (all of these should be tried as seperate steps).
