Spontaneous Reboots... pls help

[JackDaniels]

Hey, just bought a new rig

P4 Northwood 3.0GHz
MSI 865PE Neo2-PFIS2R
ASUS A9800PRO (Radeon 9800PRO)
Corsair Mem CL2

But for some reason the damn thing keep resetting spontaneously and without reason, in the middle of games and other load intensive applications. The PSU is a brand new 400W SeaSonic Super Tornado 400 that delivers 22A on the +12V line...

I Can't figure this one out

Help me Obi-Wan [H]ard-obi
You're my only Hope!

Cheers

I been having a similar problem and I found that my Radeon HATES sharing power with anything else...if possible give it it's own power on 1 channel and if you have more than 2 channels use them for other devices...if you only have 2 better off running cd drives and HD on 1 and radeon on 1.....just a suggestion, worked for me.

Check the voltages on the PSU, and make sure automatic reboots are disabled, assuming your using XP. You didn't bother to tell us the OS your using, so that leaves out some detail we can give.
