Computer Lockups

I am getting random lockup's,
i ran memtest and got no errors so it cant be the ram

-AMD Opteron UP 165 Dual Core San Diego 1.8GHz 2MB Cache (Socket 939) - Retail (CP-151-AM)
-DFI LanParty UT NF4 Ultra-D (Socket 939) PCI-Express Motherboard (MB-014-DF)
-HIS Excalibur ATI Radeon X1900 XT 512MB GDDR3 AVIVO TV-Out/Dual DVI (PCI-Express) - Retail (GX-048-HT)
-Western Digital Raptor 74GB WD740GD 10,000RPM SATA 8MB Cache - OEM (HD-015-WD)

-Zalman CNPS9500-LED Aero Flower

i have the cpu at 2.3Ghz and it doesnt go over 45oC even at full load
I am running the newest Omega drivers


any suggestions of what it could be?
are there any tools to test all the components seperately/together to see what is the culprit

ummm....
Double check all your temps including motherboard, CPU, Graphics GPU EVERYTHING and make sure nothing is getting too hot !
It COULD also be a software problem, try a system restore to earliest date possible.
